How do I clear up backups space on Mac Book Pro hard drive
I recently deleted some large photo files from Aperature that were backed up and stored offsite to free up space. My space did not free up even after removing and deleting from Aperature (That file reflects the delete) and emptying the trash - I then rebooted to see it if cleared up. It appears all these files are still taking space as Backups - see below - how do I clear that out? FYI - I also backup my Macbook on a portable external drive so I dont need this backup.
iMac (21.5-inch Mid 2010), Mac OS X (10.7.5)
