I updated yesterday with the Combo Updater and had some problems with the instructions to -x boot into safe mode after the video booted in a garbled state. That was a lot of sweat for nothing, there are others ways to boot into safe mode that I had forgotten about . . . and the help on the forum was awesome.
Everything is working fine, and I agree with another post that my Mini seems faster, perhaps considerably faster. I did have a little problem with "About This Mac" at the apple drop-down menu (left side of the menu bar) giving a "Unknown" name for Atom, but I ran "aboutthismac.pkg" and that fixed it all up.
I think Bluetooth is actually working better. It has always been tedious to get this thing to lock on to my BT
keyboard, but somehow that seems better now, too. Log out, reboot, and restart are all better, so I'm good, I'm happy.
Good luck to everyone with their updates . . .
