I tried to remove Chess.app from my Mac:

  • Moving to Trash: “Chess.app” can’t be modified or deleted because it’s required by macOS.
  • Trying to change permissions for everyone in Get Info: The operation can’t be completed because you don’t have the necessary permission.
  • chmod 755 Chess.app/ in Terminal works, but then doing sudo rm -rf Chess.app/: long list including rm: Chess.app/: Operation not permitted

So how can I remove it?


Chess.app is, as everything else installed by default, protected by SIP and can't be removed. If you absolutely want to reclaim the 5mb used by the application you can

  • Reboot into Recovery Mode to disable SIP
  • Reboot normally, log in and remove Chess.app
  • Reboot into Recovery Mode to enable SIP
  • Reboot normally
  • (and then repeat this with every macOS upgrade)

See How do I disable System Integrity Protection (SIP) AKA "rootless" on OS X 10.11, El Capitan? for details about disabling/enabling SIP.

  • +1 for pointing out that it's only 5MB in size (although it's 8.8MB on High Sierra) :) – Scott Earle Oct 27 '17 at 6:35
  • I always found it interesting that people want to get rid these pre-installed apps. If it's that they take up too much space or that they get in your way... well, either way I'm not sure I get it. I believe all pre-installed apps together take up ~2GB of your disk space. And you don't really need to ever see those apps depending on how you launch apps in general. I guess that is like 400 more songs you could stuff in... or one movie. – Joonas Oct 27 '17 at 6:50
  • @ScottEarle du says 4952 here (High Sierra 10.13.1 Beta), Finder says "7’885’411 Byte (5.1 MB on Volume)". Whatever that means :-) – nohillside Oct 27 '17 at 7:16
  • @patrix The bundle is compressed transparently and occupies 5.1 MB of disk space. The (real) uncompressed bundle size is 7.9 MB. – klanomath Oct 27 '17 at 7:28
  • Yeah I don't understand why so many sizes, either. My machine (also 10.13.1 beta 5) says 8,776,171 bytes (7.3MB on disk). I give up :) – Scott Earle Oct 27 '17 at 8:09
