So, I am on my sisters new computer (I'll have to wipe the history after this), and I noticed how slow it was, and I thought that was weird because this one is newer then my one downstairs and that she barely has anything on it so why would it go more slowly? I looked at About This Mac and it said its maximum is only 4 Gigabytes (I have had my iMac for years now and I still got 50 Gigabytes left). So I went to my room, pulled out my camera and laughed at the fact that the little SD card I help in my hand could hold 2X more then this massive computer. I am downloading a REALLY big update on my one downstairs so it's gonna be a few hours so I'm using this one. But this one is going REALLY slow because she has a lot of games on it. So it there a way to use my SD to let the computer "spread out" at all?!?!!!!!!!
