macOS Sierra: Stable Release
UPDATE: MPG now recommends waiting six (6) months to go to macOS Sierra. Key functionality has been destroyed, like Apple Mail and Copy/Paste. And some of it might not be fixed any time soon. And bottom line is that there is ZERO benefit to macOS Sierra.
MPG is contemplating downgrading back to El Crapitan, but this is difficult because at the least, AppleMail destroys (updates) mailboxes to some new format that is irreversible.
Unlike the past 3 or 4 releases, macOS Sierra is probably safe to go ahead with right away. Finally, relief from the Apple quality failure onslaught.
The macOS Sierra install has been running on the late 2015 iMac 5K and 2013 MacBook Pro with no issues for 12 days now. Today I installed on the 2013 Mac Pro, based on stable results with those two machines.
There are at least some compatiblity issues with macOS Sierra; as usual MPG recommends WAITING AT LEAST 3-4 weeks for working professionals to make a major OS upgrade, with 3-4 months advised for production shops, testing the waters with just one machine to start. Those with “special needs” like printing should probably never upgrade the OS once a machine dedicated to that task is operating wel.
- There was an install glitch and it happened on BOTH the late 2015 iMac 5K and 2013 Mac Pro: the install hangs with a dark screen, and the computer has to be forcibly powered off. Installation resumes after powering on and is was successful after that one glitch.
- The usual issues crop up: Apple removes certain software such as the version of Java required for Adobe DreamWeaver to work, which requires reinstalling the legacy Java package.
- diglloydTools works fine, with no obvious issues.
- My daily tools including Photoshop, DreamWeaver, TextWrangler, RawDigger, Safari and so on, and all seem to be OK. Exception: Adobe software update window has drawing problems on one computer, and so does RawDigger. So there are some glitches.
- Apple Mail has severe performance problems and other bugs.
