And considering the distance you're moving, (10.6 50 10.10) there may be migration problems.
It's been awhile since I had to upgrade more than one version, but I've heard that recent OS X's are able to go more than one step at a time with good migration. What have others experienced going to yos from earlier-than-mav?
FWIW, I was at the Apple Store in Albany NY today, looking at a 5K Retina iMac. The salesperson claimed that migration from 10.6.8 to 10.10 should pose no problems. Maybe she was right and maybe not... I'll find out when I do it.
No, I haven't bought the iMac yet, but I must say that it looked terrific. Text is razor sharp compared to the standard iMac. I will probably take the plunge within the next month or so. If I wait until 10.11 is out, the migration may have even more problems.
