No real problems of note here. I’ve recently finished upgrading all of my primary use machines at home and in my classroom to High Sierra, and they’re all working beautifully.
2010 Mac Pro
2016 MacBook
2010 MacBook
2009 iMac
2009 Mac mini
2008 iMac
I believe that HS has reached "maturity" and is stable.
However, I would STILL choose to install it as HFS+, and NOT APFS -- not yet.
But that's just me.
The verdict in my case is that I'm going to go back to Sierra for the second time. I wanted to try HS again now that it's *cough* more "mature". And I'll stay there unless Mojave offers more than a dark mode. High Sierra is slower than Sierra, some apps crash or hang when quitting. I don't care what the people with "no issue with HS" will say, HS is still a worthless upgrade. ...This is on mid-2012 cMP 5,1, SSDs and 40GB or ram.
I haven't had too many problems other than MS 2011 which I expected.
Late 2013 MbP and 2011 MBA. My 2010 MP runs Sierra server and will not be updated in it's lifetime.
When High Sierra came out it was not stable... till the last update.
.6 version works finaly great on my mac mini 2012 i7.
Running cubase and protools.
For me it looks like its stable like Low Sierra 10.12.6.
