Oof. Since updating, QuickLook has become useless. Whether in the Finder or in an open dialogue from another app, previews don't load. If you work with a gazillion video and graphic docs a day, that makes the Finder next to useless.
The only solution I've found is to force quit Finder. But then, after a few successful previews, it's back. Anyone else have this problem – or find a real solution?
I've had a Mac since 1984 and, if I don't get a solution soon, this will be the first time I have to uninstall and go backwards in systems. I really miss the days when the MacOS was pretty damn rock solid AND the UI kept to its own elegant Mac-like principles.
