How can I delete the Backups.backupdb folder?
When I try to upgrade my MacOS it says "this drive is being used for a Time Machine backup". My Time Machine is backing up to an external drive but somehow there is a Backups.backupdb folder on my main internal drive. I cannot find a way to delete or remove this folder from my internal HD. There is no "Move to Trash" option and when I try to change permissions to read & write it says I don't have the necessary permissions.
