mine is macbook2,1; i will take a look at the EFI firmware update.

As for the ram, i bought a pair and upgraded it myself, no issue there. Permission repair and all that stuff seem to be useless in my situation because it is really slow no matter what. So thats why i got a faster hdd to see if the speed improves.

I will wait until tomorrow to see if theres any input about my method.
