Snow Leopard in Macbook Pro 9.2 (mid 2012)

Hi!!! I need to install Snow Leopard in my macbook pro 9.2.

I Have made the instalation in any kind of macbook pro (versions 5,6,7,8) but I can´t do it in my 9.2.


What I get in Verbose mode is:


Loading system library caches com.apple.kext.caches startup extensions.mkext........


and then it stops.

I´m doing the installation with a Snow Leopard 10.6.7, because it´s the version that runs with Ivi Bridge.

I have tried with differents Hard Disks and even with 1333Mhz RAM (the 9.2 have 1600Mhz).

What can I do?? because I need to run the Snow Leopard at all cost


Thanks

MacBook Pro, Mac OS X (10.6.8), macbook pro 9.2, snow leopard

You should never try running other than the exact memory specification for your mac.

As Sig said: You can not install a lower OS version than what the hardware was delivered with.

Your MBP 9,2 was delivered with Lion 10.7.4, so there is no way that you downgrade to SL.

It has to do with the embedded hardware drivers for the hardware.

Maybe you can run it in a virtualizer as VM, the best chance with Parallels Desktop 8 (but I am not 100% sure), most probably with an install DvD. The Virtualizer app will do the "translation".
