xattr -cr
and a space (don’t press return yet!) - Drag the game icon onto the Terminal window, to
- Press return to run the command
Something went wonky with the “extended attributes” in the game files and they’re just getting in our way, so this command just clears them (-c
is for clear, and -r
applies it to the entire game’s files).
Not sure if you needed such a detailed explanation, but hope at least someone learns something!
