I recently bought a hybrid seagate HDD/SSD for my Macbook Pro. I have read that I will need to put a fresh copy of OSX on there and then use migration assistant to transfer my files. As I already have OSX Mountain Lion 10.8 on my current harddrive, how would I transfer the OSX to the new drive? My Macbook Pro originally came with 10.6 Snow Leopard. My new drive is in an enclosure, ready to transfer. I have been using this information to guide me through the steps:http://eshop.macsales.com/articles/how-to-transfer-your-data-from-your-old-drive-to-a-new-drive But I am concerned as to how I will go about this, as to whether I will need to instal Snow Leopard before hand or instal Mountain Lion externally before it even goes in my Mac.
