Apple Releases Second Beta of macOS Mojave to Public Beta Testers

by

Apple today seeded the second beta of an upcoming macOS Mojave update to its public beta testing group, one week after seeding the first macOS Mojave public beta. Today's second public beta is the same as the third developer beta, released earlier this week.

Beta testers who have signed up for Apple's beta testing program will be able to download the macOS Mojave beta through the Software Update mechanism in the Mac App Store. Subsequent betas are installed in a different way, using the Software Update icon in System Preferences.


Those who want to be a part of Apple's beta testing program can sign up to participate through the beta testing website, which gives users access to iOS, macOS, and tvOS betas.

Potential beta testers should make a full Time Machine backup before installing macOS Mojave, and it should not be installed on a primary machine because betas are unstable and often have many bugs.

macOS Mojave's main new feature is a systemwide Dark Mode, which gives Mac users a new way to view the operating system. A revamped Mac App Store makes it easier than ever to discover great apps, while Dynamic Desktops give you wallpapers that subtly change throughout the day.

An improved Finder window with Gallery View, Sidebar, Quick Look, and Quick Actions makes it easier to manipulate, edit, and organize your files, while Desktop Stacks organizes all of the files on your desktop.

The Apple News, Stocks, Home, and Voice Memos apps have made their way to the Mac in Mojave, and for the first time, you can use Siri on Mac to control HomeKit products. Group FaceTime, an iOS 12 feature, is also available in Mojave and lets you chat with up to 32 people at one time.

Apple is keeping your data safer than ever with new security and privacy improvements, and Safari in macOS Mojave makes it much harder to track you through share/like buttons and via your system configuration.

macOS Mojave is compatible with 2015 and newer MacBooks, 2012 and newer MacBook Air, MacBook Pro, Mac mini, and iMac models, the 2017 iMac Pro, and Mac Pro models from late 2013 and mid-2010 and mid-2012 models with Metal-capable GPUs.

Mojave will be available in a beta capacity for the next several months so Apple can work out bugs ahead of a fall release.

Not a word in this article about what has changed from last beta and what to focus on on this release. Macrumors seems to just copy/paste the apple pressreleases every time there is an update on betas and other updates.

I like the macrumors forum, but the articles are too often sparse and without much substance, especially the mac news. (In my opinion)

More indepths articles, like in the good old mac days, please!

Today, Apple shared the latest update to macOS [name, version, build number]. This update largely focusses on bug fixes, stability, and under-the-hood improvements. It also introduces 12 new emojis.

Dark Mode is a return to the old displays when the Mac was first released. It is much easy to read black text on white background than the other way round.

On the other hand, what Apple should do is to support APFS on any disk, including Time Machine, external booting disks, etc. And release final APFS specifications, so that Alsoft can also release DiskWarrior 6 to rebuild directory of such disks.

New, faster, more powerful MacOS but the Mac hardware is becoming “vintage.”
[doublepost=1531001090][/doublepost]I agree. Apple should be embarrassed at the current state of mac desktop hardware.
