Bought a used MBP (latest version AFAIK, #a1278) with no box, no disc. Ordered Snow Leopard from apple. Bought Agility 3 SSD. I put in the SSD with the brand new snow leopard DVD and attempted to boot holding "C" to boot from the DVD. The optical drive spins up then spins down less than a minute later and the screen sticks on the grey apple logo. From all the googling I did I take it this might be an issue with compatibility between the dsic version and the MBP version, yet I don't understand how this can be it when they are both current? Can it be that the SSD is not formatted for apple out of the box? I feel that if this was the case it would give me a problem AFTER it gets past the grey apple screen? Any ideas?
