macOS Sierra LogoApple released macOS Sierra 10.12.6 on Wednesday. It’s a maintenance release that, “improves the security, stability and compatibility of your Mac.” It also includes three fixes for enterprise.

In addition to the quote above, Apple’s patch notes specify:

  • Resolves an issue that prevents making certain SMB connections from the Finder.
  • Fixes an issue that causes Xsan clients to unexpectedly restart when moving a file within a relation point on a Quantum StorNext File System.
  • Improves the stability of Terminal app.

Mac users can find the update in Software Update in the Mac App Store. I haven’t been able to update yet—if anyone has the download size for the update, drop a note in the comments. Please drop any other update notes you might have, too.

There’s also a standalone combo updater available as a 1.98GB download.

I updated my new 2017 Mac laptop and after it went ok, I went to update my wife’s iMac (a late 2009 iMac) but it doesn’t show the update to 10.12.6 (it did get the iTunes update) so I don’t know if it got pulled or there’s some reason it won’t show up on this iMac running 10.12.5.

The update showed up in the Mac App Store, and including iTunes was only 1.3GB for my MBP 2012. Ran without a hiccup.
