Apple - How do I remove crashplan from my Mac
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
I had this same exact problem and no amount of "uninstalling" would get this pesky application file to DELETE. I even connected this Mac in Thunderbolt Target Mode to another Mac and tried to delete it that way. No go. I was at my wit's end, almost ready for a complete system backup, wipe and re-install.
Fortunately before getting that far, I was able to fix it by removing the "system immutable flag" via Terminal.app, using the "chflags noschg" command.
In the terminal:
cd ~/.Trash/
chflags -R noschg *
rm -fR * # or empty via Finder
Um. I just went to the folder Library/Applicationsupport/CrashPlan and clicked on the uninstaller icon. It uninstalled and it is gone now.
