I've got a 1TB SSD on a retina 13" running 10.11.1. I've used DaisyDisk, and GrandPerspective, and can't figure out what is taking up so much space; the numbers in DaisyDisk don't add up. My boot drive (the 1TB SSD) says it has 651.1GB worth of data on it. A bootable clone of the drive (created using carboncopycloner) only takes 362.9GB worth of data. DaisyDisk shows both have roughly the same size Users, Applications etc. folders. Am I missing some GIGANTIC cache somewhere? I've run disk utility first aid and everything says its fine. Any ideas?
