sizes?
I'm a little confused. My hard disk (iMac 10.11.6) shows, in the Finder - GetInfo, that the size "used" is 88.4 GB. I do a SD clone, and the size of that clone looks to be 76.1 GB. Given that discrepancy, how do I assess how large a backup disk I need for my clone? What happened to the 12.3 GB? Does SD do some kind of compression?
