Apple Releases macOS Sierra 10.12.6 With Security and Stability Improvements
Jul 19, 2017 11:05 am PDT by Juli Clover
Apple today released macOS Sierra 10.12.6, the sixth update to the macOS Sierra operating system that launched in September of 2016. macOS Sierra 10.12.6 comes two months after the release of macOS Sierra 10.12.5, an update that introduced a headphones audio fix, enhanced Mac App Store compatibility, and more.

macOS Sierra 10.12.6 is a free update for all customers who have a compatible machine. The update can be downloaded using the Software Update function in the Mac App Store.


There were no bug fixes, feature additions, or other changes found in macOS Sierra 10.12.6 during the beta testing process, suggesting the update focuses on security improvements and other small enhancements.

macOS Sierra 10.12.6 is likely to be one of the last updates to the macOS Sierra operating system, as Apple is preparing to shift focus to macOS High Sierra, the next version of macOS. Apple introduced macOS High Sierra at the Worldwide Developers Conference on June 5.

One thing life taught me, if your machine is working just as you like, don't update it. Why risk losing functionality on features and enhancement you probably don't need or sometimes might be annoying.

This is especially true when you use a machine with specific software combination for business or any kind of work. I remember when OS X was out, many people stayed on OS 9 because it did what they wanted and no reason to upgrade to a system you just don't know how it works.

It's quite the opposite: Some users find it exciting to upgrade to High Sierra. But most people who you're reading to in this thread won't update to High Sierra soon, as we typically update on summer, to get the most stable version of each MacOS release. This wasn't necessary back in the years of Tiger or Snow Leopard, but it is today, if you want the level of stability you were used to (and still... you won't match it).

I might even skip High Sierra completely, and wait til summer 2019, as HS brings a new filesystem, and I'm not sure a year will be enough to consider it fail safe in production machines.


The problem is that Apple will keep nagging you for a good 10 months on daily basis and remind you to update. I wish there was a way to stop that.

They actually never cared. That's why bugs have been allowed to persist since Yosemite and Craig Federighi has been busy making funny videos for keynotes and giving himself a gold medal for taking the macOS to a "higher level".

Craig is clueless. The type of clueless person who spends 200 bucks on a magical healing pyramid. macOS sank like a piece of lead after Jobs died.

For some reason it isn’t showing up in the App Store for me…

Never mind! I’ve got it. If I could delete this post, I would.


Wasn't showing up for me at first either! It was slowly rolling out for folks. Cheers.

I know y'all are exciting to update to 10.12.6. IMO, why don't just wait till High Sierra, which few months down the road. I doubt 12.6 would be significant.

Probably because its a rather bad idea to remain vulnerable to CVE-2017-9417 and CVE-2017-700.

CVE-2017-700 allows any audio file to perform code execution (HTML5 adverts, YouTube videos), while CVE-2017-9417 allows any wifi device within range to take control of Mac WiFi chips and run code.

Looks like the update gave my laptop a seizure. The internal display as well as the two external LG5K displays are all just flickering various colors. Wonder if I should power cycle it or wait it out.

EDIT: Unplugged both 5Ks and the update continued. Once it completed, I plugged them back in and everything is back to normal. Been mostly bug free otherwise. Hoping this update fixes an issue where one of my 5Ks would be completely dimmed down when they're both plugged in. Other then that, I've been having great performance with my 2016MBP. The only caveat being that some USB-C devices can cause my machine to hang (specifically a TrippLite USB dongle that has HDMI/Ethernet/USBA and power pass-thru).
