I just updated to the new release of macOS Catalina (19A512f), but I'm having nothing but problems. I noticed I couldn't play any music (it would play a second and then beachball for 5 seconds), then realised that any videos in a browser would beachball the browser, then I tried to QuickLook a video in Finder and it beachballed Finder.
Also, my external drives keep being ejected every 5 minutes, and I get the "You shouldn't force-eject drives!" notification. I'm leaving them unplugged for now as I don't want to damage them. (They were plugged in via my LG UltraFine display, so I'm now trying a drive plugged directly into my Mac, and it hasn't ejected so far.)
As it is, my Mac is pretty unusable, and I'm considering downgrading. But I wondered if anyone else is having these issues too? Thanks!
