Disable CrashPlanService on OSX

Since I run CrashPlan on my QNAP to back up my personal data, yet I still want to use the CrashPlan GUI on my Mac, I don’t need the CrashPlanService running in the background on my Mac all the time.

To disable the always-running CrashPlan service on OSX (verified with the latest CrashPlan app, version 3.7):

1. See if the service is running:

   ps aux | grep CrashPlanService
   

2. Disable service:

   sudo launchctl unload /Library/LaunchDaemons/com.crashplan.engine.plist
   

3. Verify the service is not running anymore:

   ps aux | grep CrashPlanService
   

4. Delete the launch control plist so the CrashPlanService doesn’t reload the next time OSX is restarted:

   sudo rm /Library/LaunchDaemons/com.crashplan.engine.plist
   

That’s it!
