Apple Seeds Third macOS Sierra 10.12.4 Beta to Developers

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

The third 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.

I know the feeling, but I'm going to assume Night Shift will be optional and default to being off (an approach I wish Apple chose for nearly all new features since about Leopard...). If anyone with the beta would like to comfirm that'd be nice.


of course this is optional - so ridiculous for people to get all up in arms about features that they don't use themselves.

Yet another 'feature' that makes me say 'thanks for that, how do I turn it off permanently?'

I can't be the only one who paid a fortune for a monitor that displays the right colours?


It's off by default.

Probably for now, but once Apple decides that its good for you, then I don't expect to be able to turn it off, that is the new Apple, who appears to have the goal to force the world to do what it thinks is correct, instead of letting the user decide.


This is what makes "MacRumors", "MacRumors", unbeilable!

Enjoy Windows 10, and ads on the start menu!

You honestly think Apple will not allow you to turn Night Shift off in the future? All features are optional. Why on earth would they make it non-optional!

Really? Tell me how to permanently turn off emoji on my iPhone then.

Remove the emoji keyboard from settings and don't use emoji.

Right...that's why it's been optional for about a year now in iOS. And that's why many other things have been optional for many many years in OS X and iOS and other Apple products.

I am sorry but you are very wrong. As a long time Mac user since OS X 10.3 Panther (still running on a PowerMac G4 through to macOS Sierra running on a Late 2009 iMac) I am qualified to criticise be it constructively or otherwise.

Granted Beta releases are what they are and shouldn't be run on production machines but there is room for criticism all the same.

What use is the TouchBar on the MacBook when it is fundamentally inferior to function keys?

What use are emojii and how does it increase productivity? It brings nothing positive to macOS.

A Previous generation Retina MacBook Pro running OS X Mavericks is infinitely superior .

No point in contacting Apple directly. The closest the Beta tester be it Developer or Public get to corresponding with Apple is via the Feedback Hub and no they don't listen as Apple have an agenda and they are sticking to it.

So which Operating systems do you work with?

Are you like myself cross platform with the advantage of bringing a balanced opinion to the table?

I work with.

macOS 10.12.3 Sierra
OS X 10.9.5 Mavericks
OS X 10.6.8 Snow Leopard
OS X 10.3.9 Panther

Apricity OS (Arch Linux)

Windows 7
Windows 10


Mate, your opinion is neither balanced nor informed. In fact, all I'm hearing is playground finger pointing and blahing.

One question I have, is do you have anything more current than a 2009 iMac or any experience of actually using a touch bar?

I work with most modern operating systems and coding platforms and have done since 1992 (yes, I remember the revolution of System 7) with a particular interest in security and solidity. So, as you can imagine I've been there for the highs and lows of them all. The progression and stability of the MacOS is unparalleled and you don't have to take my world for it, go out there and read the information for yourself.

The one thing that makes absolutely no sense to me is continuing to work with outdated software and then bemoaning the fact that the world has moved on.

Yes, there are always going to be features that one might not use in a newer release, but that's the thing with an OS, it's designed to be used by various parties for multiple uses. You will never get a special MacOS 10.x 'Guy Clark' build no matter how much you shout about hating emoji and other OPTIONAL features. No one is making you use them as you suggest.

On that subject, imagine the outcry if Apple didn't include something as basic as emoji - it would be called archaic, out of touch and pointless and you'd probably be leading the charge... Some folk are never happy, no matter what they get.

To be clear, I am overall very happy with the direction of the OS with a few minor harrumphs to features lost. There will always be 'bug bears' but being a beta tester allows me to constructively feedback and be actively involved. In the past, I've had great engagement with Apple staff both online and in person.

As for Apple hardware, I reckon it's got to be pretty hard to keep pushing the boundaries AND come up with a unique selling point MAKING SURE to include all the things that everyone wants WHILST maintaining a reputation for quality AND retaining a reputation for innovation AFTER taking an existing technology and making it fundamentally better and more user friendly.

But hey, what do I know?

Like f.lux, you'll be able to configure it to turn on and off automatically based on sunset, sunrise, or a specific time of day. If you're watching Netflix movies later at night, and you want to be able to sleep better, this really helps. It's not meant for productivity work. I'm constantly disabling f.lux when I'm doing work later at night.

Based on the Hands-On video with 10.12.4 Beta, is it possible I can get a link to the wallpaper/background that is being used in the MacBook Pro?


That wallpaper was included in macOS Sierra 10.12.3.
