Have you tried to delete CrashPlan from your Applications folder and gotten the message that the “CrashPlan app is locked” in a popup?

Here’s the solution:

  1. Shut down the CrashPlan app in the system tray.
  2. You may need to elevate permissions or use ‘sudo’ to perform some of these commands.
  3. Open a Terminal window. You can find Terminal under Utilities in the Applications folder.
  4. Enter this: cd ~/Library/Application\ Support/
  5. Enter this: rm -R CrashPlan
  6. Enter this: cd /Applications/CrashPlan.app
  7. Enter this: cd ..
  8. Enter this: ls -lhdO /Applications/CrashPlan.app
  9. Enter these two commands: chflags noschg CrashPlan.app and chflags nouchg CrashPlan.app
  10. You should now be able to go to the Applications folder and delete CrashPlan.app.
