Here's what I have: MacBook Pro (13-inch, Early 2011) Processor: 2.3 GHz Intel Core i5 Memory 4 GB 1333 MHz DDR3 Here's what I want to do: Put in two 8's (16 GB) of RAM Put in a SSD Here's why: Computer is running very slow on Yosemite. When running multiple programs (Garage Band + iMovie or Premiere + iTunes + Chrome + iPhoto, etc.), it crashes/freezes a lot. The manufacturer's specs say my model only takes 8GB RAM. Can I put in 16, or will bad things happen? I did some searches and I couldn't find a thread specifically about this topic in relation to my particular model, but if it's out there, feel free to point me to the correct thread.
