I'm still leaving Mac desktops and was viewing the Activity Monitor/System memory a little while ago. i7 has the stock 4GB. The monitor shows - Free - 362 MB Wired - 1.09 GB Active 1.49 GB Inactive 1.03 GB Used 3.62 GB I'm thinking that this shows that I'm currently using most of the ram available but could be wrong. So what does this mean? Thanks!
