And dumbass me got distracted with the small shiny objects (scan direct from iPhone, fully functioning text from my Mac with the phone also keeping text records) - that I completely forgot that I never do first release upgrades, and now I'm paying the price ... having to reboot several times a day because everything just starts locking up to a point where it won't even shut down without a hard reboot ... and my MacBook Pro was running so well before I did this .... *sigh*
I had also few problems with system freeze. Mine problem was (at least I think and didn't experience again), that I used to use caffeine app to prevent computer going to sleep in any way (hdd sleep, screen sleep, etc.), so this app didn't work after system upgrade, so every time computer screen went to sleep, or screen saver went on, computer got frozen.
So what I did: turned off screen saver (don't need them), turned off hdd sleep after X minutes, turned off screen sleep after X minutes (anyway I liked always keep my mac with caffeine on) - and didn't experience any freeze again.
Anyway, you are right, but I'm expecting some update any time soon, so the issues would be addressed. This has been true with almost all releases of macOS. The difference is, that problems disappear after some time, while on MS Windows they grow like mushrooms after the rain, and unfortunately barely somebody picks them.
