I have a late 2008 MacBook, Intel Core2 Duo. I recently did a clean install of Mountain Lion using a 8Gb thumbdrive as a BootDrive. I'd like to buy an SSD to replace my slow HDD. Physically swapping the drives seems pretty straight-forward. But I've never set-up a new drive before. Can I just put my usb boot drive into the usb port and go from there? Or do I need to do anything else? Do I need to format the new drive? Thanx so-much!
