Hi, I'm trying to install Snow Leopard on my Macbook (13" 2009). Before I can even agree to the terms and conditions, the installer throws up a message saying "Mac OS X Snow Leopard cannot be installed on this computer.". As far as I know my computer meets the requirements (intel processor, dvd drive, 1gb ram, apple supplied video card etc). I called the Mac helpline and they had no idea and advised me to take it to the nearest "Genius" store (using the term loosely). Before I give those jokers ago I thought I'd see if anyone here could help me. Thanks a heap for your time.
