I have installed today the ram and memory by myself.
First you need to connect the SSD with your mac and make a 1:1 clone of your hdd on the sad, then you can exchange it nd it will boot normal.
To connect the sad you need a kit where where u can afterwards put the hdd in as and external hard drive.
BTW its SATA 3 Speed for both now 6gbits))
So does this mean I can buy an optibay and put in a SATA 3 SSD and it will work without problems? This sounds excellent!
