So I've been all over the place (internet, youtube, etc.) trying everything I can find to remove the 140GB of "other" taking up space on my HD. I've upgraded to El Capitan, removed iMessage attachments, verify and repair permissions, run Clean My Mac, deleted any iPhone apps, removed any iPhone backups and many other attempts to figure out just what is causing this? anyone have any suggestions? my head is starting to bruise from beating it against the desk.
