The initial version of macOS High Sierra released this morning limits the new Apple File System (APFS) to Macs that have all-flash built-in storage, excluding iMacs and Mac mini machines that feature Fusion Drives.
Apple announced the limitation last week in a support document that said the initial release would not allow Fusion Drives to be converted to APFS, implying future support, and now Apple software engineering chief Craig Federighi has confirmed APFS will indeed be coming to Fusion Drives in a later update.
Federighi shared the info in an email sent to MacRumors reader Michiel, who asked if APFS would be added later.
"Yes, we plan to add support in a future update," replied Federighi.
Fusion Drives, available as a storage option for Apple's iMac and Mac mini desktop machines, combine a hard drive with flash storage to provide the speed of an SSD with the affordability of a standard hard drive. Frequently accessed files are stored using flash storage, while less frequently used files are moved to the hard drive.
The first macOS High Sierra beta released in June did include support for Fusion Drives and converted iMacs and Mac minis to APFS, but support was removed in subsequent betas and was not reimplemented, presumably due to stability problems and bugs with the feature.
Apple File System is a more modern file system than HFS+ and is optimized for solid state drives. It is safe and secure, offering crash protection, safe document saves, stable snapshots, simplified backups, and strong native encryption.
Developers who happened to install APFS on their machines have been provided with instructions for how to convert back to HFS+ for the time being.
Apple's macOS High Sierra press release also confirms the company's plans to introduce APFS support for Fusion Drives and standard HDDs, but Apple has not offered a timeline on when we can expect the APFS update to be released.
The iPhone 8 and the iPhone 8 Plus include support for the Enhanced Voice Services (EVS) audio codec that offers improved voice quality and better call reliability, KDDI president Takashi Tanaka told Engadget Japan in a recent interview.
EVS is the first codec that offers up to 20 kHz audio bandwidth for higher quality audio, higher frame/packet error resilience, and higher compression efficiency than other speech codecs for a better user experience.
In the United States, T-Mobile supports Enhanced Voice Services and has offered EVS since early 2016. According to T-Mobile, EVS on its network offers improved voice call reliability in areas of weaker signal for fewer dropped calls and higher-fidelity calls for more realistic voice audio.
AT&T, Sprint, and Verizon have not yet announced support for EVS.
Apple does not mention support for the feature in its iPhone 8 documentation, but UK carrier EE also recently confirmed that the iPhone 8 and 8 Plus work with EVS in a press release announcing EVS support on its network.
Along with T-Mobile and EE, several other carriers in Europe and Asia also support EVS, including Vodafone Germany and NTT DoCoMo.
Snapchat is gaining a new feature called "Sky Filters," which are able to detect the sky in an image and then layer different effects on top, much like Snapchat's existing face-based filters.
Snapchat told TechCrunch that the new filters are rolling out starting today on iOS an Android. Available filters will rotate on a daily basis and will include virtual weather, sunsets, stars, rainbows, storm clouds, and more.
The new filters will be accessible with a swipe upwards on a photo like other filters so long as Snapchat recognizes the presence of a sky in the image.
In the future, Snapchat's filters will be able to take advantage of advanced face tracking capabilities using the TrueDepth Camera in the iPhone X. While this won't affect Snapchat's environment-based filters, it will make the company's face-related features far more realistic-looking.
Snapchat can be downloaded from the App Store for free. [Direct Link]
iOS 11 and macOS High Sierra bring new features to several apps, and some of the biggest changes have been made to the Notes app. Along with a new Document Scanning feature outlined in a prior how to (iOS only), the Notes app also includes support for pinning and tables.
How to Pin a Note in iOS 11
Open the Notes app.
Open an existing note or created a new one.
In the list of note titles, swipe to the right on the note that you want to pin.
The swipe will bring up an orange push pin. Tap it to pin the note to the top of the list of notes.
How to Pin a Note in macOS High Sierra
Open the Notes app.
On the left of the app, there's a bar that lists all of the notes in a particular folder.
With the trackpad, swipe right on one of the notes to bring up an orange push pin icon.
To pin the note, click on the push pin.
The note will now be listed at the top of the app in a new "Pinned" section.
How to Add a Table to a Note in iOS 11
Open the Notes app.
Open an existing note or create a new one.
On the keyboard in the Notes app, tap the icon on the left side of the app that looks like a set of boxes.
This adds a table to the note.
To add more columns or rows, tap on the little gray bar next to an active row or column. The same method deletes them.
To rearrange columns and and rows, tap the same little gray bar to highlight a row or column and then drag it into a new position.
To copy a table, share a table, covert a table to text or delete a table, hold a finger down on the table icon in the Notes app to bring up additional options.
How to Add a Table to a Note in macOS High Sierra
Open the Notes app.
Open an existing note or create a new one.
At the top of the Notes app, click on the menu icon that looks like a table.
Clicking that icon automatically inserts a table into the Note.
To add, delete, or rearrange rows and columns, click on the little gray handles that are located at the top and side of the table.
Compatibility
All of the new features in Notes are available on the iPhone, the iPad, and Macs, so long as the devices are running iOS 11 or macOS High Sierra.
Apple's iPhone SE, introduced in March of 2016, is the sole device that the company continues to sell in a smaller 4-inch form factor.
The iPhone SE wasn't updated in September alongside the iPhone 8, iPhone 8 Plus, and iPhone X, and there are no real rumors hinting at an imminent refresh, but that hasn't stopped designers from Curved.de from imagining what an iPhone SE with an iPhone X makeover might look like.
Curved.de has mocked up an iPhone SE with the same general form factor as the existing iPhone SE, but with the elimination of the bezels, it has a larger 4.7-inch display.
Like the iPhone X, the imaginary iPhone SE features an OLED display and a TrueDepth front-facing camera with accompanying notch. The iPhone X only features a black front-facing panel, but Curved.de's iPhone SE is depicted in multiple colors, some with a white front panel. Curved.de also imagines aluminum back, a dual rear camera, and rounder edges.
While it's fun to imagine these changes in the iPhone SE, in reality, it's not clear what Apple's plans are for its 4-inch device.
There's been a questionable rumor suggesting Apple supplier Wistron is gearing up to manufacture a next-generation iPhone SE set to begin shipping in the first quarter of 2018 and an entirely unverified rumor that suggests the next model will have an A10 chip, 2GB RAM, a 12-megapixel rear camera and a 5-megapixel front-facing camera, but we have not heard any information about a new iPhone SE from a reliable source at this point.
Whether or not Apple plans to introduce another version of the 4-inch phone or stick to larger sizes going forward remains to be seen.
With the public release of macOS High Sierra, Apple introduced some additional features to its native Safari web browser. Here we'll cover just what they are and how you can customize them to make your web browsing experience a more enjoyable one.
Individual Website Settings
One of the most welcome new changes in Safari 11 is the ability to customize a range of settings for individual websites. Once these options are set up for a site, Safari applies them automatically so you don't have to bother with them again. Here's how.
Navigate to a site you frequently visit.
Right-click on the URL or website name that appears in the address bar, and select "Settings for This Website". Alternatively, click Safari in the menu bar and you'll see the same option under Preferences.
Select your preferences from the drop-down pane that appears below the address bar to control how the website behaves, either by checking the boxes or selecting a setting from the available options.
Safari's built-in Reader mode strips online articles of extraneous web page furniture to make them more readable. Reader is usually enabled by clicking an icon that sometimes appears in the far left of the address bar, but you can check "Use Reader when available" to switch to this by default.
The box next to "Enable content blockers" lets you set whether to activate any ad-blocking extensions you may have installed, while the Page Zoom setting lets you adjust the size that website fonts and images display, allowing you to make them easier to read and navigate.
With the Auto-Play setting, you can prevent websites from playing video the moment you visit a page, which should make browsing a lot less infuriating. The options are Allow All Auto-Play, Stop Media with Sound, and Never Auto-Play.
The last three options in the preferences pane let you choose whether to allow or deny the site access to your Mac's camera and microphone, and whether to enable location detection. If your preference is likely to change from time to time for these, set them to "Ask", and Safari will query you whenever access is requested by the site.
Safari Website Preferences Tab
Helpfully, Apple has added a new tab to Safari preferences for you to keep track of your individual website settings. You can access it at any time by clicking "Preferences" In the Safari menu bar and selecting the Websites tab.
Here you'll find lists of websites that are currently open as well as ones you've customized in the past, categorized by individual settings, where you easily can adjust them. You'll also see an additional setting in the General column listing your preference for websites you've visited that have prompted you about receiving Notifications.
Intelligent Tracking Prevention
Another new feature Apple has added in the latest Safari is Intelligent Tracking Prevention (ITP). Apple's own testing has found that popular websites can harbor more than 70 cross-site tracking and third-party cookie trackers that all silently collect data on users while making the browsing experience increasingly sluggish.
To solve this, ITP uses local machine learning to identify cookie types and partition them or purge the cross-site scripting data of suspect ad trackers, without affecting the functioning of helpful cookies like those containing localized data or login details, for example. The feature should increase user privacy as well as boost overall browsing speed. You don't need to do anything to enjoy the benefits of ITP – it's on by default.
Following this morning's public release of macOS High Sierra, Apple has updated its iMovie for Mac app with support for High Efficiency Video Coding, aka HEVC or H.265.
As outlined in our in-depth post on HEVC, HEVC is a next-generation video compression standard that's been introduced in both macOS High Sierra and iOS 11. HEVC brings high-quality video with better compression rates, for files that are approximately half the size of H.264, the previous standard.
With support for HEVC, iMovie is now able to import videos in the HEVC format on macOS High Sierra. Today's update also improves compatibility when sharing to YouTube, a feature introduced in iMovie for iOS a couple of weeks ago.
Though iMovie has been updated with HEVC support, Final Cut Pro X, Apple's professional video editing software, has yet to gain support. iMovie can be downloaded from the Mac App Store for free. [Direct Link]
All iOS devices and Macs on High Sierra will support HEVC playback, with encoding/decoding hardware acceleration available on newer iOS devices and the latest 2017 Macs for faster performance and less battery drain.
In other Mac-app related news, iBooks Author, Apple's free app for creating iBooks, has also been updated following the release of macOS High Sierra. iBooks Author, includes support for wide color gamut images and the ability to add images and video from the Photos app using the Media Browser or drag and drop.
According to Apple, the glass used for its new iPhone 8 and iPhone 8 devices is the most durable glass ever used in a smartphone, but that hasn't helped the device resist shattering in a series of drop tests.
SquareTrade, a company that provides extended warranties for electronic devices, conducted drop tests on the iPhone 8, iPhone 8 Plus, and, for comparative purposes, the Galaxy Note 8, which also has a glass body.
Both of the iPhone 8 models and the Galaxy Note 8 shattered on all sides in every single drop test, including front and back drops at a distance of six feet, a 22-foot shot drop test, and a tumble test. Each test was conducted using the same equipment.
Ultimately, Square Trade gave the iPhone 8 a breakability score of 67, the iPhone 8 Plus a breakability score of 74, and the Galaxy Note 8 a breakability score of 80. At 67 and 74, iPhone 8 and 8 Plus are at "medium risk" of breakage from a drop, while the Galaxy Note 8 is at "high risk." The Galaxy Note 8 fared worse because it was non-functional after some of the tests, while the iPhone 8 and 8 Plus remained usable despite the broken glass.
YouTuber JerryRigEverything also did a drop test on the iPhone 8 in a case and without a case. It survived a drop from knee height and was okay after one fall from waist height because it landed on the aluminum frame, but the glass broke after a second waist-high drop. The iPhone 8 in a case unsurprisingly fared better.
Another YouTube drop test that compared the iPhone 8 Plus to the iPhone 7 Plus, and the iPhone 8 Plus shattered on the first drop. The iPhone 7 Plus survived a drop on its back, of course, as it has an aluminum body.
Drop tests are never scientific and are not a reliable measure of durability because of the many variables involved when a device is dropped, but it's clear that even with the most durable glass used in a smartphone, the iPhone 8 and iPhone 8 Plus are more prone to catastrophic breakage than previous-generation iPhones.
While both sides of the iPhone 8 and iPhone 8 Plus are now made of glass, the display and the body don't appear to share the same repair costs, so if you drop it on the wrong side, it's going to be an expensive fix.
With AppleCare+, Apple charges $29 for replacement for a broken display, but a broken glass body is subject to the $99 "other damage" repair fee rather than the screen replacement fee. Sans AppleCare+, a display repair for the iPhone 8 costs $149 and an "other damage" repair costs $349. iPhone 8 Plus repairs are even more expensive at $169 for the display and $399 for the body.
Apple is also charging more for its AppleCare+ plans this year, with AppleCare+ for iPhone 8 priced at $129 and AppleCare+ for iPhone 8 Plus priced at $149. AppleCare+ covers two incidents of accidental damage.
iOS 11 and macOS High Sierra bring Live Photos to FaceTime, allowing you to preserve a special memory while video chatting with friends and family. Whenever you use the new Camera button that's at the bottom of the screen on a FaceTime call, it captures a photo, but don't worry - this can't be done in secret and the other party is always notified when an image is captured.
How to Take a Live Photo in FaceTime
Initiate a FaceTime video call.
While in the call, press on the camera button that's located at the bottom of the display to the left of the red button for ending a call.
Pressing the camera button captures a photo from the camera of the person you're chatting with, so if they have the front-facing camera on, you'll get a full image of their face as if they had taken the photo themselves.
The Live Photo taken from the FaceTime call can then be found in the Photos app along with the rest of your photos.
Every time you take a Live Photo in FaceTime, the person on the other end of the video call receives a message letting them know that a Live Photo was taken, so capturing an image during FaceTime isn't something that can be done in secret. FaceTime Live Photos also don't capture audio.
Disable Live Photos in FaceTime
If you don't want people to be able to take a Live Photo when FaceTiming with you, it's easy to disable. Here's how:
Open the Settings app.
Scroll down to the "FaceTime" option and tap it.
Toggle off "FaceTime Live Photos."
With this setting toggled off, people you chat with will not be able to use the Live Photo in FaceTime feature. You can still take Live Photos of others, however, as long as their setting isn't toggled off.
FaceTime Live Photos only works when both FaceTime participants are running iOS 11 and have the option to enable/disable the feature. If someone isn't using iOS 11 and you attempt to capture a photo, you'll get a warning that all parties need to be running the new software.
FaceTime Live Photos on the Mac
FaceTime Live Photos are also available on Macs running macOS High Sierra. Capturing an image is done by clicking on the camera button, and toggling off Live Photos can be done on a Mac by opening the FaceTime app, choosing Preferences from the menu bar, and deselecting "Allow Live Photos to be captured during Video calls."
Following the release of a new version of iOS, there are typically complaints about battery problems, issues with apps, and minor bugs, and the launch of iOS 11 has proven to be no exception.
On reddit, numerous users who have installed iOS 11 claim to be experiencing much slower app performance, app crashes, and other similar issues. The initial reddit post calls launching apps "an absolute chore," a sentiment echoed by dozens of additional comments.
Ever since I upgraded, launching apps is an absolute chore. Safari, Reddit, ESPN, Yahoo, texts, etc all have a terrible time opening. They either crash back to home, freeze and require closing the app or take well over a minute to load. I never had a single issue with my 7+ before last night and now suddenly it's like this phone is stuck in quicksand. I've never had to hard reset this phone before but I've had to do it twice in the past two days.
Users are complaining that their phones "just get stuck on apps" and that a hard reset is the only way to fix the problem. Reddit, Snapchat, Twitter, Facebook, Messenger, Safari, and more are all affected apps. Sometimes, apps refuse to open just launching from the Home screen, while at other times, apps launched from Notifications won't work, and there are issues with Bluetooth.
I've been using the beta and it's been super fine for me. But now on the GM I get all the same issues. Apps don't launch, or if they finally do they crash. Things are freezing and crashing. Sometimes just bringing up CC stalls my phone and makes it unresponsive. Something in the update broke the Bluetooth controls connection and now I can't use the skip button from my transmitter (which worked in the beta) to change songs.
The Now Playing widget in the Control Center is also a chief complaint, with multiple users unable to control songs on Spotify and Apple Music using the widget, and some users say their battery life has taken a serious hit since updating.
Not all customers who upgraded to iOS 11 are seeing these issues but based on the reddit thread, it seems a fair number of people are having problems. App updates and subsequent iOS 11 updates are likely to resolve these issues over time, but customers who want an immediate fix can try some of the methods reported to work on reddit
Some reddit users claim that resetting their settings (Settings --> General ---> Reset --> Reset All Settings) fixed all of the app issues, while others have restored their devices and set it up as new to solve the problem. Others have backed up and restored and had better results. From one reddit user on backup and restore:
Exactly. I think people think this is a placebo effect but it really does work. Brought my 6S from a sluggish beast to more or less the same performance I had in iOS 10.
Multiple iPhone models appear to be affected, with redditors reporting issues on the iPhone 6s, iPhone 7, iPhone 7 Plus, and other earlier models. The iPhone 8 and 8 Plus do not appear to be affected, and there are few complaints about iPad Pro models.
With the release of macOS High Sierra, Apple is now collecting data from the Safari browser using differential privacy technology, reports TechCrunch. Apple is aiming to gain information about browsing habits to help identify problematic websites that use excessive power or too much memory.
This form of data collection is the first of its kind for Safari, aimed at identifying sites that use excessive power and crash the browser by monopolizing too much memory. Apple is also documenting the popularity of these problematic domains, in order to prioritize which sites it addresses first.
Apple first announced its adoption of differential privacy in 2016 alongside the debut of iOS 10. Differential privacy is a technique that allows Apple to collect user information while keeping user data entirely private. It uses hashing, subsampling, and noise injection to enable crowd-sourced learning without compromising user privacy.
Differential privacy is already in use on Mac and iOS devices for emoji use, search predictions, predictive text, and other small features that use machine learning for improvement.
Because of this, Apple does not have a specific message about the new Safari data collection when macOS High Sierra is installed, and it is lumped in with the general Mac analytics data notice that is presented when setting up a new Mac. From Apple's Privacy notice regarding analytics:
If you agree to send Mac Analytics information to Apple, it may include the following: - Details about app or system crashes, freezes or kernel panics. - Information about events on your Mac (for example whether a certain function such as waking your Mac was successful or not). - Usage information (for example, data about how you use Apple and third-party software, hardware, and services).
Analytics data contains your computer's hardware and software specifications, including information about devices connected to your Mac and the versions of the operating system and apps you're using on your Mac. Personal data is either not logged at all in the reports generated by your Mac, is subject to privacy preserving techniques such as differential privacy, or is removed from any reports before they're sent to Apple.
While users are given the option to turn off analytics when setting up a Mac, there's also a Security and Privacy setting that can be accessed to turn it off any time. To get to the feature, click on the Apple at the top of the menu bar, and choose "System Preferences." From there, open up Security and Privacy, select the "Privacy" tab and then choose Analytics to choose whether or not to share data with Apple.
With the release of the Apple TV 4K, Apple has started offering 4K content in its iTunes Store at HD prices, meaning the cost of a 4K movie maxes out at $19.99. Apple has also upgraded previously-purchased HD content to 4K at no additional cost to consumers.
In response, Amazon has started lowering the prices on 4K titles on its Amazon Video service in the UK. As Pocket-lint noticed, While prices could previously reach upwards of £24, 4K titles now range in price from £3.99 to £13.99. Amazon's 4K library isn't as large as Apple's, but with 4K streaming becoming more prevalent, it should continue to grow.
It's not yet clear if the price drops will expand to additional countries, but to remain competitive with Apple, Amazon will need to lower prices across the board. Many 4K movies in the U.S. continue to be priced at $29.99.
Amazon's video content will be available to watch on the Apple TV when Amazon releases its Amazon Prime Video app later this year. There's currently no word on when the app might be released, but a rumor earlier today suggested it could launch this Thursday alongside NFL's Thursday Night Football games.
Amazon is also rumored to be planning to release its own upgraded Fire TV set-top box with support for 4K and HDR in the near future.
Update: It appears the price drop on 4K titles is limited to the UK at the current time, and this article has been updated accordingly.
Apple's native Photos application got an update with the release of macOS High Sierra, including new library browsing features, a reorganized editing window, enhanced image recognition, and some additional tools to help make your photos look even better. Keep reading to find out what's new in the Photos app.
Browsing the Photos Library
Apple has tweaked the main Library interface in Photos. Whereas previous versions of Photos let you use tabs along the top of the screen in place of an optional sidebar, Apple has now fully embraced the latter as the main navigation area, and has also added a draggable selection counter to the browser that you use to move or export batches of photos.
The new sidebar is divided into five sections: Library, Devices, Shared, Albums, and Projects. The Library section is where you can select from different browsing options, including Memories, Favorites, People, Places, and a useful new option called Imports, which organizes your photos based on when they were imported into your library.
The Shared section contains links to any shared albums you've created, while likes and comments appear in the Activity feed. The Albums section meanwhile contains two collapsible sub-sections called Media Types and My Albums. Media Types contains auto-generated views of your photos filtered by Selfies, Panoramas, Live Photos, and the like, while My Albums contains all the albums you have manually created. Lastly, Projects is where any books, cards, calendars, prints, or slideshows you're working on appear.
The Editing Window
The Photos app also got a reorganized editing window in High Sierra. In addition to the sidebar, there's now a toolbar along the top of the screen with three tabs that let you toggle through three different editing sidebars, making for a less cluttered interface all around. Notice too that the One-click Enhance option is now an icon at the top right of the screen, next to the Done button.
The Crop tab corrals the traditional crop functions in the sidebar, while the Filters tab is home to an enhanced selection of image filter presets, each with three variations to choose from – Vivid, Dramatic, and Black and White.
Selecting the Adjust tab switches the sidebar to all the usual advanced editing tools, including two new ones, Curves and Selective Color. The triangle beside each tool allows you to expand it for more options, or collapse it to make room for others.
Live Photos
Apple has introduced additional tools for editing Live Photos, including the ability to manually select the static image that represents the clip. This is achieved by adjusting the slider at the bottom of the editing window and selecting Make Key Photo.
You can also now trim Live Photos, and even apply effects such as a Boomerang-like back-and-forth effect and an ethereal Long Exposure style, similar to when a shutter has been left open for a long time. The icons at the bottom left of the editing window let you mute the clip or turn off Live Photo entirely.
Third-Party Photo Editor Support
Lastly, Apple has enhanced the integration of its native Photos app with third-party apps, which should come as good news to those looking to broaden their editing options.
For example, it's now possible to open a photo in a third-party app right from within your Photos Library. Not only that, any edits that you make within that third-party app are automatically saved back to your Photos library.
A number of popular third-party apps have already announced their support for Apple Photos, including Pixelmator Pro, Aurora HDR, Luminar, and Creative Kit. Several photo printers have also signed up, including Whitewall and Shutterfly. You can find more apps that support Photos by checking out the new dedicated section in the Mac App Store, which can also be accessed from within the Photos app.
A recent support document on Apple's website confirms that you don't need one of Apple's USB-C power adapters to fast charge the latest iPhones.
Apple says the iPhone 8 and iPhone 8 Plus, and presumably the iPhone X, can be fast charged with any comparable third-party USB-C power adapter that supports the USB Power Delivery specification.
An official Lightning to USB-C cable is still needed, and it's not included with any iPhone. Apple charges $25 for a one meter cable, and $35 for a two meter cable, in the United States. There aren't any MFi-certified alternatives yet.
Apple's own USB-C power adapters that support USB-C Power Delivery include:

A major new version of iStat Menus, a popular Mac system monitor for power users, has been released today for macOS High Sierra.
One of the biggest new features in iStat Menus 6 is configurable notifications for a wide range of events, based on CPU, GPU, memory, storage disks, networking, sensors, battery, power, and weather.
iStat Menus now has a Notification Center widget for CPU usage, memory, top CPU and memory processes, load averages, disk space, and uptime.
You can be notified, for instance, when your public IP has changed, if your internet connection is down, if CPU usage is above 60 percent for more than 10 seconds, or even of daylight saving time changes.
iStat Menus 6 features an all-new weather menu with the current temperature and conditions, hourly and weekly forecasts, notifications, and more. Weather-related notifications can be configured.
The update also introduces new ways to color and style the menu bar icons, dropdown menus, and graphs, including light and dark backgrounds.
Another key feature is hotkeys support for opening and closing dropdown menus using your keyboard, including time, CPU, GPU, memory, storage disks, networking, sensors, battery, power, and more.
Other changes include improved accessibility, localization, AirPods battery level support, dropdown menu reordering, automatic fan set switching based on events, and many other new features outlined in the version history.
iStat Menus is built into the macOS menu bar, providing power users with convenient access to system information, such as CPU and GPU usage, memory stats, fan speeds, temperatures, disk usage, and battery life.
iStat Menus 6 is available now for $18 on developer Bjango's website. Existing users with version 3.0 or later can upgrade for $9.99.
macOS High Sierra, released to the public today, could be impacted by a major security flaw that could allow a hacker to steal the usernames and passwords of accounts stored in Keychain.
As it turns out, unsigned apps on macOS High Sierra (and potentially earlier versions of macOS) can allegedly access the Keychain info and display plaintext usernames and passwords without a user's master password.
Security researcher and ex-NSA analyst Patrick Wardle tweeted about the vulnerability early this morning and shared a video of the exploit in action.
For this vulnerability to work, a user needs to download malicious third-party code from an unknown source, something Apple actively discourages with warnings about apps downloaded outside of the Mac App Store or from non-trusted developers. In fact, Apple does not even allow apps from non-trusted developers to be downloaded without explicitly overriding security settings.
As demonstrated in the video above, Wardle created a proof-of-concept app called "keychainStealer" that was able to access plaintext passwords stored in Keychain for Twitter, Facebook, and Bank of America. Wardle spoke to Forbes about the vulnerability and said it's actually not hard to get malicious code running on a Mac even with Apple's protections in place.
"Without root priveleges, if the user is logged in, I can dump and exfiltrate the keychain, including plaintext passwords," Wardle told Forbes. "Normally you are not supposed to be able do that programmatically."
"Most attacks we see today involve social engineering and seem to be successful targeting Mac users," he added. "I'm not going to say the [keychain] exploit is elegant - but it does the job, doesn't require root and is 100% successful."
Wardle has not provided the full exploit code for malicious entities to take advantage of, and he believes Apple will patch the problem in a future update.
As Wardle has not released the full exploit code, it has not been double-checked by MacRumors or another source, so full details on the vulnerability are not known just yet.
Apple has not yet responded to requests for comment about the potential vulnerability.
With the official release of iOS 11 and macOS High Sierra, Apple introduced support for a new image format called HEIF, which uses the file extension HEIC. Apple sees HEIF as a worthy successor to the JPEG format. So what makes it so good that it can replace an industry standard that's been in use for almost 25 years?
What is HEIF?
HEIF stands for High Efficiency Image Format and can be considered the still-image version of the HEVC video codec that Apple's ecosystem now officially supports. (You can learn more about HEVC here.) The HEIF standard wasn't made by Apple – it was developed in 2015 by the MPEG group, which also invented the AAC audio format used in iTunes.
Benefits of HEIF Over JPEG
As the name implies, HEIF is a more streamlined method of storing image data and offers better quality than the traditional JPEG format. For example, HEIF supports image transparency and can capture a more extended color range than JPEG (16-bit versus 8-bit), which should increase the accuracy of photos taken on Apple's latest iPhones. At the same time, a HEIF-encoded image should be around half the file size of an equivalent-quality JPEG, so users will be able to keep twice the number of shots on their Apple devices (or in iCloud) before they max out their storage capacity.
In addition, HEIF files include a 320x240 embedded thumbnail that's four times the resolution but only twice the file size of a standard JPEG thumbnail. HEIF images can also be rotated and cropped without altering the image or re-saving them, all of which makes working with HEIF files that much faster than JPEG on both Mac and iOS devices.
HEIF also brings other benefits that JPEG doesn't offer because it's unlike your typical image format. That's because it's also capable of acting as a container for multiple files. This should be a boon for anyone who takes bursts of photos or lots of Live Photos – which can be edited in multiple new ways in iOS 11 – but it also means HEIF could become a wholesale replacement for GIF.
HEIF Compatibility and Image Sharing
Currently, Apple only supports HEIF image encoding on iOS devices with a minimum A10 Fusion processor, so that includes the 2017 10.5-inch and 12.9-inch iPad Pro, the iPhone 7 and iPhone 7 Plus, and of course Apple's new 2017 range of iPhones. Owners of these devices can check their camera is encoding photos in HEIF by going to Settings -> Camera -> Formats, and ensuring the "High Efficiency" option is selected. The "Most Compatible" option means photos will be encoded in JPEG format.
HEIF is supported on all Macs capable of running macOS High Sierra, and many macOS applications work natively with HEIF, including Photos, Preview, and Quick Look. This means macOS users might consider converting their JPEG image files to HEIF for greater storage or network benefits.
The transition to HEIF within the Apple ecosystem should be mostly transparent, but if users need to move HEIF content outside of that ecosystem, it's worth looking into transcoding options (JPEG, for example) to provide the best backwards compatibility for other users. Happily, iOS 11 will auto-convert HEIF images to JPEG when they are shared to devices running earlier versions of iOS, non-Apple devices, and popular social media sites, or when they are passed over to apps that don't yet support the standard.
With the arrival of iOS 11 and macOS High Sierra, Apple is supporting a new video format called HEVC, which replaces the previous standard most commonly used on Mac and iOS devices, namely H.264 / AVC. So why has Apple adopted the HEVC format, and what difference will it make to the end user?
What is HEVC?
High Efficiency Video Coding (HEVC), also known as H.265, is a next-generation video compression standard developed by a group of encoding experts called the Joint Collaborative Team on Video Coding. The HEVC video format has been in existence since around 2013, and HEIF is the still-image version of the standard that both iOS 11 and macOS High Sierra also support. (You can learn more about HEIF here.)
Benefits of HEVC
Apple's decision to adopt HEVC basically means two things - higher quality video and better compression rates. The HEVC standard enables a video to be compressed into a file that is about half the size (or half the bit rate) of H.264 / AVC. To put that another way, a HEVC video file offers significantly better visual quality than an AVC file of equivalent size or bit rate. While results vary depending on the type of content and the encoder settings, videos encoded in HEVC typically exhibit fewer compression artifacts and offer smoother playback than videos encoded using AVC.
According to Apple, HEVC can compress 4K video files to up to 40 percent smaller file sizes than AVC without losing quality, which means users who upgrade their devices to iOS 11 and macOS High Sierra will be able to take the same high-quality videos without using up as much storage space. At the same time, transferring high-resolution video files between devices and over networks will require significantly less bandwidth, a key advance considering new 4K iTunes content launched for the new Apple TV 4K.
Compatibility and Support
To capture and encode video in the HEVC format, iOS devices need to have at least an A10 Fusion processor, so owners of iPhone 7 or later and 2017 iPad Pro are fully able to take advantage of the standard. To check if your device's camera is capturing video in HEVC, go to Settings -> Camera -> Formats, and ensure the "High Efficiency" option is selected.
All iOS devices running iOS 11 and all Macs on High Sierra will support HEVC playback, with encoding/decoding hardware acceleration on newer iOS devices and the latest 2017 Macs offering faster performance combined with less battery drain.
