Had a weird Finder thing...no windows would open, was still running, dock still ok, files visible on desktop...restart cured it. But can't see my Synology. Will investigate.
Yeah I had WindowServer crap out and die on me within the first 20 minutes or so. As soon as I logged in after the update, checked a few things and was on a Reddit thread with a YouTube video. Clicked play on the YouTube video and the whole Finder froze on me. Mouse still worked for awhile but eventually the pointed disappeared. Had to manually reboot it and when it came back up, filled out my first feedback report for a WindowServer crash.
