Hello everyone. - Right now I'm on the 2011 13" core i5 Macbook pro, and recently downloaded the iStat Pro widget. Sometimes I'll go ahead and take a look at it. Everytime I watch it, my free ram goes down and down. Right at the moment I have 958 mb ram free, what does that mean? I'm not too much into that kind of stuff.. I have 4 gb of ram on my Macbook, but why does it show 958 mb, when the only thing I'm doing on it is just web browsing? Thanks.
