Is there any way to delete apps that were added by Apple in the Mavericks 10.9 update? In particular, I'm talking about iBooks.app. When I try to delete it, OS X tells me that it can't be because it's required by OS X.
sudo killall bookstoreagent sudo tar -czf /Applications/iBooks.tar.gz /Applications/iBooks.app sudo rm -fr /Applications/iBooks.app
keeps you a working backup, just in case you need it back:
cd /Applications sudo tar -xzf /Applications/iBooks.tar.gz
there is no need to alter any other files, nor to play with LaunchAgents or Daemons. Once the App is gone, iTunes gains back the books functionality. I read some evil suggestions on the interwebs.
