Apple Seeds First Beta of macOS Mojave 10.14.3 Update to Developers

Apple today seeded the first beta of an upcoming macOS Mojave 10.14.3 update to developers, five days after releasing macOS Mojave 10.14.2, which addressed an issue with external displays and included other bug fixes.

The new macOS Mojave 10.14.3 beta can be downloaded through the Software Update mechanism in System Preferences after the proper profile has been installed from Apple's Developer Center.


We don't yet know what improvements the second update to macOS Mojave will bring, but it is likely to include bug fixes and performance improvements for issues that weren't able to be addressed in the macOS 10.14.2 update.

If and when we discover what's new in the 10.14.3 beta, we'll update this post.

How to Use Your iPad as a Second Screen for Your Mac

Duet Display is an app made by former Apple engineers that allows you to use your iPad as a second screen for your Mac. In this article, we'll explain how it works and the steps you need to follow to get things up and running.


Duet Display is a great way to extend your Mac's desktop and can come in especially handy when you're working away from home and want to broaden your productivity space, but don't have the luxury of a dedicated external monitor.

In earlier versions of macOS, the app was hampered by changes to Apple's operating system that caused its developers no end of problems, but the latest Duet update (v2.0.3.8+) released on December 5 appears to have resolved those issues thanks to the introduction of full hardware acceleration support.


Duet Display is actually one of two apps best known for letting users leverage their iPad as a second screen for their Mac. The other is Luna Display ($79.99), but that app uses another implementation that requires two small dongles to ensure a consistent low-latency connection.

Duet Display on the other hand is a pure software solution and a lot more affordable at $9.99, which is why we've chosen to cover it here.

How to Use Your iPad as a Second Screen for Your Mac

  1. Launch the App Store on your iPhone or iPad and download Duet Display ($9.99).

  2. Open a browser on your Mac, navigate to www.duetdisplay.com and click the Download Mac button at the top of the webpage to download the free Mac client.

  3. Once the Duet client app is downloaded to your Mac, drag it from the Downloads folder to the Applications folder.

  4. Double-click the Duet Mac client to launch it.

  5. Connect your iPhone or iPad to a free USB-A port on your Mac using a Lightning cable. (If you're using a Mac that has the newer USB-C ports, you'll need to use a Lightning to USB-C cable, which Apple sells in 1-meter and 2-meter lengths.)

  6. Launch the Duet app on your iPhone or iPad and wait a moment while it communicates with the Duet Mac client. You should see your Mac's desktop mirrored or extended on your iPad screen once a successful connection is made.
Once you've got things working, it's worth checking out Duet's display options: click the Duet applet in your Mac's menu bar and if you have an iPad connected you'll see a button to enable a touch-sensitive MacBook Pro-style Touch Bar along the bottom of your iPad's screen.


If you click Advanced Settings, you can choose from a number of Display options to scale the output to your iOS device. The pre-defined resolutions allow you to see either larger text or more desktop space, and Duet helpfully recommends which scale to pick based on device model.


Check the box next to Mirror Display if you want to duplicate your Mac's desktop on your iPad rather than extend it. There are also options to enable Retina display mode, increase the framerate from 30 to 60fps, and switch the image quality from Regular to High, all of which require more device energy.

If you click the cog wheel in the Duet menu bar applet, you'll also find some additional settings worth attending to. If your Mac has a dedicated graphics card then you can set Duet to use it exclusively for faster performance, alternatively you can limit it to the integrated graphics for energy efficiency.

There are also menus to enable or reduce transparency on your iOS device display, an option to start Duet at login, and a link to change the Display Arrangement of your screens in System Preferences.

If you get on with Duet Display, there are Air ($19.99 annually) and Pro ($24.99) versions that offer additional features like wireless connectivity and Apple Pencil support, respectively. For more information and support, check out the Duet Display website.

Pixelmator Pro Gains Redesigned Color Balance Adjustment, New Automator Actions, and More

Popular Mac-based photo and image editing software Pixelmator Pro received a significant update today, introducing several new features.

The update includes a wheel-like redesigned Color Balance adjustment option designed to offer a more "fluid and intuitive" way to adjust the color balance of photos. According to the Pixelmator team, the feature was inspired by professional video grading and editing tools.


With the new color adjustment tool, users can add color tint to shadows, midtones, and highlights while also adjusting the brightness and saturation of the colors. Color Balance can also be improved automatically using a new Core ML-powered algorithm.

Today's update also allows users to resize images using scaling algorithms. The Lanczos algorithm, for example, better preserves small details when cutting down on the size of an image, while Nearest Neighbor allows for the resizing of pixel art while keeping the blocky design.

Two new Pixelmator Pro actions for Automator are included as well, as is a new Grain adjustment tool that adds frame-style grain in a "more natural and realistic way."

Pixelmator Pro recently won Apple's Mac App of the Year award for its range of professional level editing tools available at an affordable price.

Pixelmator Pro can be downloaded from the Mac App Store at a $29.99 price until Friday, at which point the cost of the app will go back up to $39.99. [Direct Link]

Hands-On With LG's $1,500 34WK95U UltraWide 5K Display

At CES in January, LG debuted a new UltraWide 5K display, the 34WK95U, which just recently launched. We managed to get our hands on one of the new super huge monitors, and we checked it out in our latest YouTube video.

Subscribe to the MacRumors YouTube channel for more videos.

LG's UltraWide 5K display is far from cheap, priced at $1,499, which makes it more expensive than many of Apple's notebooks and the new Mac mini. For that price, it includes a 34-inch Ultrawide 21:9 Nano IPS display, a 5120 x 2160 resolution with a 60Hz refresh date, HDR support, and Thunderbolt 3 connectivity.


Design wise, the display features a curved base with height and tilt adjustment features, with several ports available on the back. There's a Thunderbolt 3 port, two USB-A ports, a DisplayPort, 2 HDMI ports, a USB Type B port, and a 3.5mm headphone jack. It supports up to 85W of power delivery, enough to power Apple's 15-inch MacBook Pro, and there are a set of 5W speakers at the bottom.


There's a single control button on the display that you'll need to use if you want to adjust features like brightness or speaker volume, with controls not available in macOS.

You can connect LG's UltraWide display to any of Apple's Thunderbolt 3-compatible Macs, including the new MacBook Air, the new Mac mini, and recent MacBook Pro models.

At 34 inches, the UltraWide monitor offers up a huge amount of screen real estate to work with, ideal for photographers, designers, and videographers. The 5K display of the monitor looks great, and while we didn't think it quite matched the crispness of the iMac Pro, we appreciated the extra space.


It's worth noting, however, that at its full 5120 x 2160 resolution spread over 34 inches, everything ends up looking quite tiny, but running at 2560 x 1080 as a Retina display results in content appearing too large. As a result, the best solution is to run at a scaled sweet spot resolution of 3360 x 1417, which gives you ton of screen real estate, and despite the scaling, content still looks good.

Some customers who have purchased the UltraWide 5K Display have run into compatibility issues with the 2018 MacBook Pro models equipped with 560X graphics cards, with an update in the works to fix it. We tested the UltraWide 5K Display with a MacBook Pro model equipped with a 555X graphics card and found similar issues, although Apple has just released macOS 10.14.2 and the release notes mention a fix for what sounds like a similar but not identical issue, so we'll be checking to see if performance improves for us.

The LG 34WK95U UltraWide 5K Display is undoubtedly a gorgeous display, but its high $1,500 price tag means that it's firmly aimed at creative professionals and not for the average consumer. Combine that price tag with the compatibility issues we and others have run into, and it's hard to recommend this display, at least until we're confident Apple and/or LG have the kinks worked out.

What do you think of LG's UltraWide 5K Display? Let us know in the comments.

Note: LG provided MacRumors with 34WK95U UltraWide 5K Display for the purpose of this video, and it was returned following the conclusion of filming. No other compensation was received.

macOS Mojave 10.14.2 release notes:
  • Adds RTT (real-time text) support for Wi-Fi calling.
  • Adds a menu item to News for opening a story in Safari.
  • Resolves an issue that may prevent iTunes from playing media to third-party AirPlay speakers.
Enterprise-related:
  • Allows administrators to enable FileVault via MDM for mobile accounts and users created by MDM.
  • Allows users to reset their login password at the login window when that password has expired via a password policy.
  • Resolves an issue that prevents displays from working when connected to MacBook Pro models introduced in 2018, if certain third-party USB graphics devices are also connected.
Additional details on the macOS Mojave operating system can be found in our dedicated Mojave roundup.

Apple Releases Safari Technology Preview 71 With Dark Mode Enhancements, Bug Fixes, and Other Improvements

safaripreviewiconApple today released a new update for Safari Technology Preview, the experimental browser Apple first introduced over two years ago in March of 2016. Apple designed the Safari Technology Preview to test features that may be introduced into future release versions of Safari.

Safari Technology Preview release 71 includes bug fixes and feature improvements in a number of areas, including the most substantial tweaks to Dark Mode in several months.

The new Safari Technology Preview update is available for both macOS High Sierra and macOS Mojave, the newest version of the Mac operating system that was released to the public in September.

The Safari Technology Preview update is available through the Software Update mechanism in the Mac App Store to anyone who has downloaded the browser. Full release notes for the update are available on the Safari Technology Preview website.

Apple’s aim with Safari Technology Preview is to gather feedback from developers and users on its browser development process. Safari Technology Preview can run side-by-side with the existing Safari browser and while designed for developers, it does not require a developer account to download.

Mac Developers Reminded to Have Their Apps Notarized as Apple Tightens Security

Apple today reminded Mac developers that it is encouraging them to have their apps notarized, meaning that the apps have been scanned by Apple and checked for malware and other security issues.


Notarization is not currently a requirement for apps distributed outside of the Mac App Store, but Apple says it will "more prominently highlight notarization status" starting in the spring of 2019. And in an unspecified "upcoming macOS release," Apple will require any Developer ID-signed apps to be notarized.
When users on macOS Mojave first open a notarized app, installer package, or disk image, they'll see a more streamlined Gatekeeper dialog and trust that it does not contain known malware. Starting spring of 2019, macOS Mojave will more prominently highlight notarization status. In an upcoming macOS release, Gatekeeper will require Developer ID–signed software to be notarized by Apple.
Apple introduced the notarization process for macOS Mojave back in June at WWDC, providing an extra level of confidence for users that apps are free of malware while also giving Apple finer-grained controls to shut down specific problematic releases instead of having to revoke an entire Developer ID.

Apple has stressed that notarization is not a full app review process and is only intended to analyze apps for security purposes.

iFixit Begins Selling 2018 Mac Mini RAM Upgrade Kit, Save Up to $275 Versus Apple

Unlike the previous 2014 model, the 2018 Mac mini has user-upgradeable RAM. The repair experts at iFixit are now selling a do-it-yourself RAM upgrade kit for the 2018 Mac mini that can save you hundreds of dollars.


The upgrade kit includes 16GB or 32GB of 2,666MHz DDR4 RAM, the same type of memory Apple uses in the 2018 Mac mini, along with all of the tools and bits needed to complete the upgrade: an iFixit opening tool, a spudger, angled tweezers, a precision bit driver, and three types of 4mm Torx precision bits.

2018 Mac mini models are equipped with 8GB of RAM by default, but they can be configured with 16GB or 32GB of RAM on Apple's online store for an extra $200 or $600 respectively. By comparison, iFixit charges $164.99 for its 16GB kit and $324.99 for its 32GB kit, reflecting savings of $35 and $275 respectively.

Three things to keep in mind:
  • This is iFixit-branded RAM that matches Apple's specifications.
  • If you ever need in-warranty service on your 2018 Mac mini, and Apple detects that you opened up the computer, the Genius Bar may deny service. However, iFixit says this is illegal in the United States under the Magnuson-Moss Warranty Act.
  • There is a risk of damaging the Mac mini if the upgrade is not completed carefully.
Those interested in proceeding can follow iFixit's 2018 Mac mini RAM replacement guide.

iFixit also sells the 16GB RAM modules individually for $159.99 each.

How to Get Unique Alerts for VIP Emails Received on Your Mac

In the last installment of our regular how-to series, we showed how you can set up an iOS device to get unique alerts when emails are received from your VIP contacts. In this article, we're going to show you how to do the same thing on your Mac.

In the native Mail application in macOS, the standard way of ensuring you receive new message notifications from VIPs is to go into Mail's Preferences and select VIPs in the New message notifications dropdown list.

Setting up VIP alerts this way is all well and good, but it prevents you from receiving notifications for all other messages coming into your inbox.


A better solution would be to set up a rule in Mail that plays a specific sound or bounces the Dock icon when a message is received and the sender is in your VIP list. Here's how to do it.

How to Get a Unique Alert for VIP Emails


  1. Launch the Mail app on your Mac.

  2. Select Preferences... from the Mail menu bar.

  3. Select the Rules tab.

  4. Click Add Rule.

  5. Give your rule a name in the Description field.

  6. For If, select Any.

  7. For the first condition, select Sender is VIP from the first dropdown list.

  8. Under Perform the following actions: select Play Sound from the first dropdown list. (Another option available here is Bounce Icon in Dock.)

  9. Under Perform the following actions: choose a sound to play from the second dropdown list.

  10. Click OK.

  11. Click Apply.
With the rule set up, you'll now get a unique alert for every VIP mail you receive that you'll be able to distinguish from regular new message notifications as they come through.

Apple Seeds Fourth Beta of macOS Mojave 10.14.2 to Developers [Update: Public Beta Available]

Apple today seeded the fourth beta of an upcoming macOS Mojave 10.14.2 update to developers, two weeks after seeding the third beta and a month after releasing the macOS Mojave 10.14.1 update.

The new macOS High Sierra 10.14.2 beta can be downloaded through the Software Update mechanism in System Preferences after the proper profile has been installed from Apple's Developer Center.


We don't yet know what improvements the second update to macOS Mojave will bring, but it is likely to include bug fixes and performance improvements for issues that weren't able to be addressed in the macOS 10.14.1 update.

No new features were discovered in the first three 10.14.2 betas, but we'll update this post if anything new is found in the fourth beta.

macOS Mojave 10.14.2 comes shortly after the release of macOS 10.14.1, an update that brought support for Group FaceTime on the Mac and introduced new emoji characters.

Update: Apple has also made a new public beta of macOS 10.14.2 available to its public beta testers.

How to Manage File Associations in macOS

In macOS, the Open With contextual menu that appears when you right-click (or Ctrl-click) on a file provides links to all the applications installed on your Mac that are associated with that file type.


At the top of the list is the default app that macOS launches whenever you double-click on files that share the same suffix or extension, with other apps associated with the file type below that, and an Other... option at the bottom which lets you choose an alternative app in case the one you want to use isn't listed.

You can easily change the default app associated with a particular file to something else. To do so, click Get Info in the contextual menu and select another app from the Open With: dropdown list in the file's Info pane. To use that app to open all files sharing the same extension, click the Change All... button and select Continue.

Clearing the Open With Menu


If you've installed a lot of applications on your Mac through the years, you may find that some apps appear in the Open With menu that really have no business being there given the kind of file you've selected.

As well as unrelated apps, you may even see references to "ghost" apps that you removed from your Mac long ago. All of which results in a long and cluttered list of launch service links you won't use.

Unfortunately the list isn't directly editable, but there are a couple of ways that you can clear the cruft from it. One option is to grab Titanium Software's free Onyx system utility and run a task to rebuild the Launch Services database.


Alternatively, if you're comfortable with a command prompt you can open a Terminal window and run the following command, which does the same thing:

/System/Library/Frameworks/CoreServices.framework/Frameworks/
LaunchServices.framework/Support/lsregister -kill -r -domain local -domain system -domain user



Leave the command to run for a few minutes while the LaunchServices database rebuilds, and when the prompt reappears type killall Finder and press Enter to see the changes take effect.
