When CrashPlan uninstall fails, one solution is to reinstall CrashPlan and follow the steps in this support article.
Because uninstall has already failed, the problem may be that the "system immutable flag" is set for /Applications/CrashPlan.app or its contents. In Terminal, try ls -ldO /Applications/CrashPlan.app
and ls -ldO /Applications/CrashPlan.app/Contents
. The ls
command may show something like this:
drwxrwxr-x@ 3 root 102 schg 13 Jul 14 20:36 CrashPlan.app
If you see the schg flag, run these commands.
sudo chflags -R noschg /Applications/CrashPlan.app
sudo rm -fR /Applications/CrashPlan.app
If chflags
fails, the flag may be unset only when the system is in single-user mode.
If rm
still causes the "Operation not permitted" error, CrashPlan.app may be locked in Finder. If it is locked, trash /Applications/CrashPlan.app. If Finder asks about moving locked items to the trash, click continue
. Empty trash and when Finder asks about removing locked items, click Remove All Items
.
To completely remove CrashPlan, remove these folders if they exist.
- /Library/Application Support/CrashPlan
- ~/Library/Application Support/CrashPlan
There may also be com.code42
files in these folders that were not removed.
- /Library/LaunchAgents
- /Library/LaunchDaemons
- ~/Library/LaunchAgents
