10.8 booting a 10.6.8 drive in cMBP

[Craigy]

OK. So, I've just got a new 2012 cMBP, put an SSD in the optical bay and all is good. However, I then connected my old 17" via FW800 in target mode and used CCC to clone the 10.6.8 drive to the 2nd 750gb internal HD on my new cMBP.

When I startup on 10.6.8 I get to the grey loading screen with the apple logo, but that's where it stays. I've left if for 10-15 mins and no joy.

Tried the PRAM, starting in safe-mode - still nothing.

Booted back onto the 10.8 SSD and ran disk utility. Verified the disk - looks fine and checked it was a GUID partition.

Anyone got any ideas how I can get the 10.6.8 drive to boot?

Cheers
Craig

You cannot boot 10.6.8 on a 2012 Macbook Pro. It simply will not ever boot.

Thanks, Jeez what a pain. OK. So, if up upgrade from 10.6.8 to 10.8 or 10.7 on my 17" and then CCC that drive to the cMBP - that should work right?

Yes, but only if Lion is 10.7.4 or newer.

Yes, but only if Lion is 10.7.4 or newer.

The 2012s required a specific 10.7.4 build, so 10.7.5 or later, really.

OK -thanks. I think I might as well upgrade the 17" to 10.8.2 and then CCC that drive onto the new cMBP.

I'd use the free version of SuperDuper to make the clone. CCC no longer has a free version that supports ML. Disregard if you have the paid version of CCC.

OK - thanks didn't realise that. I'll use SuperDuper instead. Thanks.
