Recently got a MBPr 15", used the migration tool to migrate pretty much everything from my old volume, which was a ext. HDD (fw400) connected to my Mac Mini Intel Core Duo (circa Mar 2006 IIRC). My mini was upgraded to the latest possible version of OSX that Mac's of that era are allowed to be updated to, not 100% sure of version, 10.6.8 IIRC? When I did the migration, it created a 2nd login acct rather migrate everything to the existing acct, apparently this was necessary because the existing login acct name used, was exactly the same as the one I'd used for the old acct on my Mac Mini. BUT..... Thinking it might be best to totally reformat, do a fresh install, and than just manually move across stuff from my old volume that I want in the new env. Thoughts on this, is it absolutely unnecessary or are there some inherently good things about taking that approach, please can you elaborate? Also, why are we not given a DVD or USB flash drive of Mountain Lion for free with our purchase? In Macs I've bought in the past, I've always been given a physical copy of the entire GM build of the OS. Can we claim a free copy or a discounted version from Apple somewhere? Also, recommendations of excellent backup/imaging sw (beyond the stock offerings) is appreciated, once upon a time I heavily researched that sort of stuff, two that still come to mind are CCC* & SuperDuper. Thank-you. *I see it's now no longer free, bummer, oh well.
