Apple Seeds Third Beta of macOS Sierra 10.12.6 to Developers [Update: Public Beta Available]

Tuesday June 13, 2017 10:06 am PDT by Juli Clover

Apple today seeded the third beta of an upcoming macOS Sierra 10.12.6 update to developers, two weeks after seeding the second 10.12.6 beta and a month after introducing macOS Sierra 10.12.5.

macOS Sierra 10.12.6 can be downloaded through the Apple Developer Center or through the Software Update mechanism in the Mac App Store.

No significant features or notable bug fixes were found in the first two macOS Sierra 10.12.6 betas, and because Apple does not provide beta release notes, we may not know what's included in the update until it sees a public release.

macOS Sierra 10.12.6 is likely to be one of the final updates to the Sierra operating system as Apple transitions to macOS High Sierra, which was introduced at the Worldwide Developers Conference in June.

Update: The third beta of macOS Sierra 10.12.6 is also available for public beta testers.

Apple today sent out invites for an experience in Los Angeles on Wednesday, October 28, and the "Pro and tell" tagline on the invitation likely means that the rumored MacBook models with touch-enabled OLED displays will stick with MacBook Pro branding instead of the once-rumored "MacBook Ultra" name. The long-rumored "iPhone Ultra" ended up being named iPhone Duo, so speculation that Apple...

So many betas nowadays :)
Waiting for 10.13 DP 2

I guess there’s no middle ground. Some are always screaming, “Doesn’t Apple test this stuff before they release it.” “Apple’s QA is in the toilet these days” “Steve would never have allowed this.” Now we’re starting hear, “Too many betas.” “Too confusing.” “Take my hand and show me ,step by step, how to back out of this POS beta.” Apple can’t win.

Seems like a cheap way to crowd source bug spotting. The only problem I fear is that internal QC/QA has been cut in response. Some things like security really need to be done right the first time.

See what I mean?

When this goes final, I wonder if this will be the time to upgrade from El Capitan on my daily driver? I don't usually wait so long, but almost all of the new features in Sierra don't apply to me.

After bad experiences from updating soon these last years, I decided to update only once per year, in summer, when they release the last update for the current MacOS. It's somewhat drastic, but it works great for me, as it lets me work with the same level of stability I was used to in the 10.4.x - 10.6.x years. So, yes, I'm updating to Sierra when 10.12.6 gets final.

I'm still waiting to hear that PDFKit has been fixed before upgrading to Sierra. Why the total radio silence on this issue from all directions?

Agree. Biggest hurdle right now for upgrading clients from 10.9.5 (yeah, that's right… it is the last "stable" OS without significant issues with productivity apps like Mail and Calendar) to 10.12 is PDFKit, because my business clients rely on PDF and being able to sign/form fill too much. It can't NOT WORK, because many of them are in the legal profession or use PDFs for legal compliance. 10.12 has remedied just about EVERY other issue I had with macOS otherwise… which makes it a shame, then, that I can't push the upgrade.
