The steps here were simple, but unexpected:
- download a file
- in finder, rename the file using Keyboard:
Enterto start rename
- Start typing a new name (but not pressing
- Try to open the file by pressing
Now this dialog appears and won't go away (it only reacts on moving with the mouse, but clicking on it fails, just as pressing
Both Finder and Spotlight now refuse to open any other file.
killall -KILL Dock killall -KILL Finder killall -KILL NotificationCenter killall -KILL SystemUIServer
Note the file is not damaged, just renamed.
