How can I get carbonite completely off my computer

It took a while, but I finally realized you have to look at the root Library - the one found directly on your Hard Disk usually named Macintosh HD -- not the Library found in your user home or through the Go menu. You can get to the Macintosh HD through the Path button on the top row of the finder window.

The following article was helpful in identifying all the places Carbonite hides its Daemon parts: https://support.carbonite.com/articles/Personal-Pro-Mac-Manually-Uninstalling

Interestingly, the carbonite .plist file kept reappearing for around 6 times after being sent to trash repeatedly -- just a second or two after moving it to trash it would miraculously reappear in Preferences -- it finally gave up when I managed to empty the Trash before it could reappear -- amazing tenacity...

It took help from MacKeeper Smart Uninstaller to finally get all of Carbonite files off my MacBook Pro late 2010 running Sierra OS v. 10.12.6.

Good luck getting rid of this vampire app...persevere -- it's a good feeling to be free of it...

What have you done?

If so, what is still left that you need help removing?

I don't know where carbonite puts its launchdaemon, but it would likely be in /Library/LaunchDaemons, but it might be in LaunchAgents or StartupItems.

Delete the plist file in the LaunchDaemon folder, then Force Quit the process in Activity Monitor. If it restarts itself, restart your Mac and it should not return.
