Why can't I delete Chess.app
Why is Chess.app "required by OS X"?
I don't use it, and I can't delete it. Is it really required by the operating system?
Solution 1:
It is a crucial component in OS X's anti-boredom technology.
Non-troll answer: Yes, you can delete it.
run this command in Terminal:
sudo rm -rf /Applications/Chess.app
enter your password and push return
Solution 2:
No, it is not required as such, but Chess is, like any other preinstalled application, protected from deletion. There are ways around it, but it's probably not worth the hassle for a meager 5 MB in disk space.
