I got a Time Capsule, set up the Time Machine Backups with it then returned it a week later. I decided to get a WD Passport USB connected External HDD instead. I have that set up with the Time Machine Backups now. For the life of me I cannot get rid of these HUGE chunks of backup files on my Macbook HDD. Below is what my storage situation is. I have read that these "backup" files are the scheduled Time Machine snapshots when the Passport isn't plugged in? And I have also read that you need to go in to terminal to deactivate the Time Machine's ability to save on the local HDD? Is this right & how do I go about cleaning out these Backups from the MBPro and keep them updating only on the Passport.
