I'm new to mac, so I'm still learning my way around here. I just got a mid 2012 13" macbook pro (base model). I'm going to upgrade the ram (4gb to 8), install a 128gb SSD for the OS and apps, and install a bigger HDD for storage (moving the optical drive to an external enclosure). Parts have all been ordered and are on the way. My question is... what is the best way order to do all of this? I was thinking of doing them RAM first... then installing the SSD in the optical bay and copying the OS to that... then replacing the original HDD with the new one. Is that the best way to do it? Is ok to have the SSD for the OS in the optical bay? Any advice is appreciated.
