Everything had on my finder sidebar today gone. Vanished. Poof... Big Sur 11.4 I did upgrade of Super Duper yesterday and used the app, only thing I can think of, but would have no idea on culprit.
Did test and things wont drag info side bar either.
Joe thanks oh yeah, reboot and also proper shut down, cause had lot of super duper upgrading to do to get that right. Just noticed I upgraded SD to laptop too, and laptop side bar is ok/ normal, just desktop.
I don't know why I didn't think of this yesterday, but Option+Command+S (⌥⌘S) should restore the hidden Finder sidebar. That will work in any Apple app that has a sidebar.
If we knew what it was we were doing, it wouldn't be called research, would it?
Acutally ok now JOe thanks, I think issue was the Facorites (which is what I use most) triangle got collapsed, and since that is to tiny and small, maybe did not see that.
