I'm wanting to upgrade my current macbook unibody 4.1's hard disk from its 160GB sata to a 128GB SSD. I have 2 questions, 1) im not a noob with hardware so is the swapover processes literally plug and play swapping the hdd for the ssd? or does it require firmware/drive locks like an xbox in order to work in a macbook (you know how apple hardware is a ****** to swap around) 2) i upgraded to snow leopard recently, i also have all the relevent leopard and snow leopard installation discs, now do i just re-install the OS and it's done with? or do apple have a 1 machine per OS installation policy like windows and it requires some tinkering, if so what needs to be done? Sorry for the noob way i asked the questions but up until a few months ago all i ever knew was DOS and windows ever since i was a kid lol Thanks guys.
