The steps here were simple, but unexpected:
- download a file
- in finder, rename the file using Keyboard:
- Press
Enter
to start rename - Start typing a new name (but not pressing
Enter
again)
- Press
- Try to open the file by pressing
Command
-O
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 Spacebar
, Enter
or Esc
).
Both Finder and Spotlight now refuse to open any other file.
I tried:
killall -KILL Dock
killall -KILL Finder
killall -KILL NotificationCenter
killall -KILL SystemUIServer
Help (:
Note the file is not damaged, just renamed.
