Running a mid-2011 27" iMac and about to throw an 512GB SSD and a 4TB HDD in. I'd like to just install OS X on the SSD before I install it in the iMac. I have a thunderbolt rig to handle this, but I'm wondering if others have done this and experienced issues. Just want to be sure that moving a drive that had OS X installed on it externally over Thunderbolt to its place over SATA internally won't create a litany of issues. And if it does, its not like its a dramatic issue; I'll just reinstall with a USB image of OS X. Any insight would be appreciated.
