How do I remove crashplan from my Mac I recently tried out CrashPlan on my Macbook, but I decided not to go through with that.  However, now that I'm not going to be using CrashPlan after all, I can't figure out how to remove their app from my Mac.

I've tried simply opening up Finder and moving it to Trash but I get the following error when I try that:



I've also tried deleting it from the command-line using rm -rf CrashPlan.app; even when I run this as root, I still get:

rm: CrashPlan.app/Contents: Operation not permitted
rm: CrashPlan.app: Operation not permitted


I also tried doing this with the GNU version of rm, but I still get an error:

grm: cannot remove ‘CrashPlan.app/Contents’: Operation not permitted


I ran, get info on the CrashPlan app in Finder, and I noticed this:



However, when I uncheck the locked field and then try to move it to Trash, I still get the same error that I got the first time.

Any ideas?
Since Crashplan runs with elevated / non-standard permissions for an ordinary app, you will want to:


Reinstall the same or newer version of the software to correct whatever changes non-standard or half-removed. (Free download from http://www.code42.com/store/)
Run the uninstaller that is inside the package contents of the app. (Documented https://support.code42.com/CrashPlan/Latest/Getting_Started/Uninstalling_The_CrashPlan_App)
Optionally delete these two folders if they exist:


~/Library/Application Support/CrashPlan
/Library/Application Support/CrashPlan
