OK, so I am completely new to mac. The last time I used a mac computer was when my family had one around 1994/1995. So, I don't know how to do completely basic things like this. I got my macbook on Saturday, less than a week ago. Last night I bought the Sims 2 at the apple store and I asked the guy if it would run good on it. He went through all of the requirements and said that my computer surpassed all of them. So I go to run it and it won't run and says I need to free up local disk space. Basically I'm wicked pissed right now and am worrying that something is wrong with my computer or he was lying and I can't return it. Someone help? How do I free this up? Is it a big deal that I need to do this after having the computer for less than 5 days? This is the only big program I've installed so far. I've only installed basic stuff like office and my printer so I don't know how it could be out of space already.
