Soon I will be having a 500GB SSD drive put in to my 2011 iMac. I will be keeping the original 1 TB HD in there for media storage and using the SSD for my apps. I will NOT be making a fusion drive at this time (maybe later) since I have not used Terminal before. I know to make a recent Time Machine back up to my external drive right before I take my iMac in. My question is what are the steps to restore my system onto the SSD from TM when I get it back? I am running most current version of Yosemite. Will I have to also nuke and pave the original HD also to use purely as media storage?
