So I was stupid enough to lost the recovery discs of my near one month old Core i7 iMac I phoned up AppleCare and they are kind enough to mail me back two recovery discs free of charge (they are white instead of grey, and printed as replacement discs) Today I tried to boot from the disc to see if it works, after I chose the language, there's a msg saying "Mac OS X cannot be installed on this computer" and the two options that I have is to restore from Time Machine or restart. So I checked the version of the disc in OSX, I discover that it's actually 10.6.1, instead of 10.6.2 which ships with Core i5/i7 iMacs. Then I phone up AppleCare yet again to see if they have send me the correct disc. The guy asked of my serial number and after a while of checking, he said they have sent me the right disc. They say the discs that come along with the core i5/i7 are actually 10.6.1 as he sees from his system. If I want to do a clean install of OSX I have to delete and format the volume first, he said. I am not convinced, how come a recovery disc version could differ from the one that's actually installed? Do you guys (i5/i7 iMac) have a 10.6.1 or 10.6.2 recovery disc? Anyone could check it for me please?
