    Apple today seeded the third beta of an upcoming macOS Sierra 10.12.3 update to developers, three weeks after seeding the second 10.12.3 beta and almost a month after releasing macOS Sierra 10.12.2, the second update to the macOS Sierra operating system.

    The macOS Sierra 10.12.3 update is available for download through the Apple Developer Center or through the software update mechanism in the Mac App Store.


    According to Apple's release notes, the 10.12.3 update "improves the stability, compatibility, and security of your Mac." No specific changes, bug fixes, or feature additions were discovered in the first two betas, but we'll update this post should any new features be found in the third beta.

    Oftentimes, with bug fixes, it's hard to tell what's included until Apple supplies detailed release notes with a release. The previous update, macOS 10.12.2, introduced several important bug fixes to resolve battery life issues, fix graphics problems, and more.

    Available since September, macOS Sierra is the latest Mac operating system. It includes Siri support, Apple Pay for the web, Universal Clipboard, Apple Watch auto unlocking, improved iCloud Drive integration, Picture-in-Picture multitasking, and dozens of smaller features that can be found in our macOS Sierra roundup.

    Update: The third public beta is also available.

    Beta train! Chugga-chugga-chugga-chugga, woot! Woot!

    (I can't install the beta anymore after reinstalling macOS from scratch last week. The beta enablement tool on doesn't appear to work for some reason.)

    I hope there is a fix with manually adding songs to iOS devices with iTunes and oh yes the side bar that is now invisible and bright :(

    Bring back the estimated time left on the battery.. the removal of that was such a troll move by Apple.

    That's why Sierra itself feels like it's a beta.

    Edit: Seems like all AMD drivers have been updated, Modification Date on all is 06-01-2017.

    Edit 2: Dug a bit deeper, all Graphic Drivers are updated, including AMD, Intel and Geforce.

    Allow Siri to control my Philips Hue lights via my Mac. Also hurry up and come out with a device to compete with Amazon Alexa and Google Home

    What about your iPhone? On iPhone 6s and 7 you can talk to Siri every time.
    What about an Apple Watch?

    Phil Schiller is right, if he says, the best personal assistant ist the one you have with you.

    Despite of that, Siri still needs lots of improvements to compete to other assistants. Especially if you don't talk english to her.

    WTH? macOS 10.12.3 Dev Beta 3 just popped up in my available updates.

    So, why didn't beta 2 appear last week when I reinstalled?

    Just in case ... hey, Apple peeps that might be monitoring this thread:

    - New (and better) mac Mini, please. Bring back a quad core option.

    I second this. Until then, I found a workaround that adds the time remaining back to the menu bar.

    [pasted from OS X Daily]

    Restore from a Prior MacOS Release
    This one is a bit more advanced and involves mucking around in the system folder. It’s also trickier because you must have the file from MacOS 10.12.1 or earlier after you have updated to 10.12.2. If you plan ahead of time, you can simply copy the file yourself from the following location:

    /System/Library/CoreServices/Menu Extras/

    Locate the “” file from 10.12.1 or earlier and make a copy of it to your desktop or elsewhere easy to find.

    After updating to MacOS 10.12.2, you will then restore your just backed up version of “” back into the /Menu Extras/ directory.


    You might need to disable SIP to accomplish this process successfully (be sure you enable it again afterwards), or boot into Recovery mode and move/copy the earlier version of after updating. I went with the latter approach, and it works fine.

    When is the so called AppleFS coming out? I thought that was one of the new features of Sierra...

    Cue the normal whining regarding stability. Those who signed up to the Beta programme only have themselves to blame if their system is unstable.

    Me I don't run a new release of OS X (macOS) until the .4 release hence the reason I am still running OS X 10.11.6 El Capitan.

    Stability is no trade off for new features.

    FAKE, Photoshopped.

    Just kidding, would you mind sharing this workaround.

    If it was inaccurate in many instances, is it somehow useful and better to have something that doesn't really provide any useful information (and can even provide misleading incorrect information)?

    @justperry, haha, I'd use a more realistic time remaining if I Photoshopped it! I updated my OP with the workaround. It probably isn't viable for most.

    If any of you use Better Touch Tool (which is amazing), a new update just added a time remaining (and clock) widget for the touch bar. Super useful.

    AppleFS (APFS) has been in macOS Sierra since the beginning, but with several limitations that makes it impractical for most end users:
    • APFS volume cannot be a startup disk
    • You must use Terminal command to format a volume to APFS (not Disk Utility)
    • Filenames are case sensitive only (e.g., "iPhone.jpg" and "Iphone.jpg" are two different files), which causes compatibility issues with some apps
    • Missing Time Machine and FileVault support
    I suspect macOS Sierra successor (as in 10.13, not 10.12.x) will remedy most, if not all, of these issues. I have been using APFS on external disk (which holds iTunes library) and I haven't run into any issues.

    Ohh my god!! Hell just froze!!!! This is unbelievable! New AMD drivers.... insane, never thought to see this happen *cries* :)
    Hopefully they give some performance improvements and I wonder which driver version they have implemented with this new beta release.
