Hi there. I have 2 MacBooks. One is the late 2008 unibody MacBook (2.0Ghz, 2GB Ram). The other is brand new, just got it today (2.53Ghz, 4GB Ram). The new MacBook came with a Mac OS X Snow Leopard 'CPU Drop-in DVD'. Is it possible to use that disk on my late 2008 MacBook? Or is the disk going to install drivers that are specifically designed for the new MacBook? They both run Leopard at the moment, but I want SL on my 2008. Thanks.
