I have a 2010 macbook pro. I installed new memory 4gb and 4gb. It works fine. I switched out the hard drive with a SSD. I did CCC the old hard drive but want to start fresh OS and then migrate assistant my data over. Every time I try to install snow leopard on the SSD, it either gives me an error of restarting the computer or saying it cannot be installed on this computer. The hard drive has been formatted to journaled and guid partition. Any ideas?
