Apple Seeds First macOS Sierra 10.12.1 Beta to Developers

Wednesday September 21, 2016 11:02 am PDT by Juli Clover
Apple today seeded the first beta of an upcoming macOS Sierra update to developers, just a day after releasing the new operating system to the public.

macOS Sierra Beta 10.12.1 is available for download through the Apple Developer Center and through the Software update mechanism in the Mac App Store.

It is not clear what improvements the first update to macOS Sierra will bring, but it's likely to include bug fixes and performance improvements for issues that have been encountered between the time between the beta testing period and release.

We'll update this post with any new features that are found in macOS Sierra 10.12.1.

I never install a .0 release, including 10.12.1.0 ...


I install them all. Somehow I survive.

Siri is non-functional on my 2014 5k iMac. (It can't find the iMac's internal microphone.) So I hope Apple gets that straightened out. After all, it's Sierra's most-touted feature.


First the headphone jack on the iPhone, now the microphone on iMacs ..... Apple are in a courage overdrive.

I am running the official retail version of Sierra (I was part of the developer beta programme). I since changed my SYSTEM PREFERENCES -> APP STORE -> and changed "your system is set to receive pre-release..." to NO.

Since then that option no longer appears in the APP store.

However, in my updates the BETA for 10.12.1 is showing which is exactly what I do NOT want.

How can I disable this given I've already done the above.

For some reason disabling the "pre-release updates" setting in the App Store system preference isn't working. You can solve this by opening terminal and entering:
sudo defaults delete /Library/Preferences/com.apple.SoftwareUpdate CatalogURL
Enter your password when prompted.
This will set Software Update back to using the standard non-beta catalog.

Interesting, only a day after release, curious to see what this will bring to the table...

They will have been working on 10.12.1 for at least a month, probably much longer, so it is not that surprising. There comes a time when it become too risky to add certain fixes to the 10.12.0 build and you're better off saving them for the first major update.

I'd love it if my watch would actually open my iMac as promised (yes it's a late 2015 and I have all the latest devices with the latest software updates).

I just want to put out a very real "thank you" to all of you early adopters.

Keep the bug reports coming, guys.

Makes it easy for me to resist the "upgrade NOW" urge.

Nope. I went into System Preferences > Siri and set it to use the internal microphone (which is also set as the default input for my system). Other apps have no trouble accessing the mic, but Siri doesn't seem to know it exists.


Siri blows, and probably always will. Lets just clear the air of all the nonsense and get that out of the way. It's a gimmick, and likely always will be.

(bring on the "doncha know Apple's software numbering scheme" clamor...)
(It's sarcasm, folks... there's always a .0 ot there somewhere. Programmers are rational, after all, and don't number their software like pi or e)

10.12.0. The first release had a deadline. It had to get out the door by a certain date. It is not perfect and will require tweaking and fixes over time, hence 10.12.1 is in the works, then 10.12.2 etc etc etc

Yep!
With the SDLC, 10.13 is already being coded, and 10.14 is on the board for what's coming down the pike...

Mind posting the version of Photos that's included with this BETA? The MacOS X Sierra GM build's version is "2.0 (445.1.15)" and I'd like to know whether I'd have to upgrade my external Photos libraries if I upgrade. Thanks.
