Information:

Macbbok Pro 3,1

2.4 Ghz Intel Core 2 Duo

Mac OS X 10.6.8

Going to Get Info for Chess the "Open in 32 bit mode" is not checked which from what I've seen on the internet means the computer is running in 64 bit.

Graphis card is NVIDIA GeForce 8600M GT

Install Error Message:

We could not complete your purchase. OS X Mountain Lion is bnot compatible with this computer.

Will this computer run MT? If so, how do I get it installed?

Made an Install DVD and booted with it. Got through the language choice and then chose reinstall OS X. The screen that came up had the same message as in the first post.

According to everything I can find, this Macbook Pro IS compatible with Mountain Lion but it won't install.

Macbbok Pro 3,1

2.4 Ghz Intel Core 2 Duo

Mac OS X 10.6.8 (with latest updates)

6 GB Ram

EFI64 verified

I'd really like to get this installed.
