Hello all, I would like to find out the code for terminal to tell my Macbook Pro 1st generation 2006 1.83Ghz/2GB running 10.6.7 ...that it is a Core Duo to be able to load Lion OS X. I want to try this first on an external carbon copy of HD. I know it is possible and would be fun to test out and report. Thanks for your time!! PS. I know it will be more sluggish in some apps...but just want to test out and can go back to Snow Leopard if too buggy.
