So, my iMac had to go to the Apple Store for a bunch of days to have The Mechanism repaired/replaced. Before sending it, I made a complete back up of the drive, then erased it. I should be getting it back in the next day or so. My request for opinions is this: Should I just clone the backup back to the iMac drive, or should I just do a fresh image, and rebuild from scratch..maybe clearing up random minor glitches I may have been encountering. (none I could point to, just a general scrubbing though).
