Apple Releases Third macOS Sierra 10.12.1 Beta for Public Beta Testers

Apple today seeded the third beta of an upcoming macOS Sierra 10.12.1 update to public beta testers, one week after seeding the second public beta and one day after seeding the third beta to developers. It's been two weeks since Apple released macOS Sierra to the public.

Beta testers who have signed up for Apple's beta testing program will receive the 10.12.1 macOS Sierra beta through the Software Update mechanism in the Mac App Store.

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 both iOS and macOS Sierra betas. Betas should not be installed on a primary machine due to the potential for instability.

macOS Sierra 10.12.1 appears to focus mainly on bug fixes and performance improvements to address issues that have surfaced up since macOS Sierra was first released. It also includes album support in Photos for the new Portrait feature in iOS 10 on the iPhone 7 Plus.

macOS Sierra is a major operating system update that introduces features like Siri support, cross device copy paste, improved iCloud functionality, the ability to unlock a Mac with the Apple Watch, an Optimize Storage option, and more.

Tried Siri on Mac in Swedish. She can't even play Phil Collins on Apple Music, even if she gets the sentence right. She asks if I want to Google it.


That's because Siri doesn't support torture.

Apple's software team must be working around the clock. Say what you want about the hardware, but they've been pushing out some rock-solid operating systems recently. Certainly they hold themselves to a higher standard than I can ever remember.

Good on them.

The only thing I have not been happy about with 10.12 is that the people tags in the Photo app do not sync between my iphone, ipad, and imac. Otherwise, this seems solid to me. 10.12.1 PB1 made no difference on my imac. Will install this tonight and see if anything changes.

Same hung installation problem as in the previous betas. It took a hard reset for the installation to complete.

Nah ...... well not for me. I just waited it out and it installed fine. Even though it seems to be hung it's not, the indicating thermometer doesn't seem to be working.

Likely a good side-effect of having releases without all that many features and upgrades.

I for one would not consider the fact that Preview choked on some PDF files for an entire release a higher standard. Same goes for the software RAID tool being absent for an entire release.

Fret not, there's still that one jabroni who refuses to upgrade from Mavericks because of flat icons.

That's the thing. It doesn't hang but the progress bar wasn't moving. Looked like it was stuck so I was watching and suddenly BOOM it was the login screen. No estimated time and the bar never moved higher than about 10%.
