Apple Seeds Fourth macOS Sierra 10.12.4 Beta to Developers and Public Beta Testers

Apple today seeded the fourth beta of an upcoming macOS Sierra 10.12.4 update to developers, one week after seeding the third macOS Sierra 10.12.4 beta and over a month after releasing macOS Sierra 10.12.3.

The fourth 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 on iOS devices 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, improved PDFKit APIs, and iCloud Analytics options.

Update: Apple has seeded the fourth macOS Sierra 10.12.4 beta to public beta testers.

I hate night shift on my phone, never mind the computer. imo, it seems like a solution in search of a problem.
I love it, really great at night when checking work e-mail before bed. Luckily, it's defaulted to no and is easy to keep off. Super glad they added it.

Me too, I don't get f.lux nor nightshift, colours are all off, don't want to surf the web with less than natural colours.

Think I got new firmware on my 2012 MBP, it just restarted when installing.

Edit: Yup, both my 2012 MBP and Mac Mini got a firmware update.
It's something that helps some to a noticeable degree, while just making things a bit easier for the eyes when it comes to to others. And of course there are others still that don't really get much from it one way or another or don't even want/like it. The good thing is that things of this nature are purely optional, so it kind of works out that way.

Isn't this video and the one for iOS ones that MR has posted before? I could have sworn these are repeats.
I think they include the video for those who might not really have read up much about the previous betas and just come across a particular beta article so that way they can see what's new when it comes to betas/release for that particular iOS version.
