Removing Time Machine Backups
I used to backup my iMac to an external drive. I have now sold the iMac but how do I remove the no longer needed backups to give much-wanted space on my Hardrive. I tried changing permissions but still unable to delete the Backup files. Is there a simple solution? Maybe I should just reformat the Hardrive but this is a last resort as I have many other files stored on it.
