I have a mid-2012 MBP 13". It has slowed down dramatically with frequent beachballing and so I purchased new RAM and a Crucial MX100 SSD to hopefully prolong its useful life for a few years. I am trying to strategize the best way to go about replacing these components. As for the SSD, I am not doing a double HD configuration, I am just swapping out the old HD with the SSD. I have everything I want to keep backed up, and I want to do a clean install of OSX on the SSD rather than a clone just in case I have some accumulated software/third party issues causing the slowness I am experiencing. So, my first question is: how do I go about formatting the SSD and having it ready to accept an OSX boot USB? My second question is: should I replace the HD first and get the SSD up and running before replacing the RAM, or should I put the RAM into my existing configuration and do the HD swap second? Thanks for your time!
