Apple Seeds Second macOS Sierra 10.12.4 Beta to Developers

Apple today seeded the second beta of an upcoming macOS Sierra 10.12.4 update to developers, two weeks after seeding the first macOS Sierra 10.12.4 beta and just over a two weeks after releasing macOS Sierra 10.12.3.

The second macOS Sierra 10.12.4 beta is available for download through the Apple Developer Center or the software update mechanism in the Mac App Store for those who have previously installed a beta.

macos-10-12-4-beta
macOS Sierra 10.12.4 brings iOS's Night Shift mode to the Mac for the first time. First introduced with iOS 9.3, Night Shift is designed to gradually shift the display of a device from blue to yellow, cutting down on exposure to blue light. Blue light is said to disrupt the circadian rhythm and is believed to interrupt sleeping patterns.

Night Shift can be activated through the Displays section of System Preferences, where a setting to have it come on at sunset and turn off at sunrise is available. Night Shift can also be toggled on manually through the Notification Center or via Siri.


The 10.12.4 update focuses mainly on Night Shift, but also includes dictation support for Shanghainese, cricket scores for Siri, and improved PDFKit APIs. Today's beta adds an opt-in option for iCloud Analytics that pops up after installing the update.

Oh. Nice. ~~So, it still can't be used as a boot partition?~~

Edit: I realised that I was confusing this with the next (to be released) macOS version. Ignore my question. I'm fairly certain they won't do that major a change in a minor version update.
They've announced they'd do the conversion in 2017, and they announced they'd convert it in-place... i think they'll do it in MacOS11. I'm very impressed by what it's capable off and think the limitations (like not being able to boot) are made intentionally.

Night Shift STILL does not work and does not exist on my late 2011 MacBook Pro 17". :mad:

No night shift support for an early 2011 MBP
Would have been good if Apple documented somewhere that there was no Night Shift support for a 2011 MBP!!! Otherwise I would have skipped this beta!!!

Back to f.lux!

My macbook md101 after updating sierra 10.12.3 cannot zoom in or zoom out on the quick look on finder. Is it just another bug or something?
Download the next file from : http://support.apple.com/downloads/DL1905/en_US/macosupdcombo10.12.3.dmg
Next apply the update, it might very well fix your issue.
It's the combo update so fairly big.

One note, this is normally not the place to ask for help, there are other threads for this but since you are new I think I just help you out here.
