i just bought an open box mac mini base model from Best Buy (2.3GHz I5)... i bought it from best buy while it was use by someone else before, so i didn't have the login name. I had to rest the login, cause i don't' have the previous user's password. I followed a youtube video on resetting the login user information. After that I started using it. The computer has been slow since the day one i've turned it on, it is extremely slow. I thought it was the ram problem, so i went and upgraded the ram to 8GBs, it does seem a little bit faster. But I'd expect an i5 processor be a lot better than this. Right now the mac mini is a lot slower than my old asus laptop with first gen i5 chip & only 4gb of ram. I also have a 13" macbook air ultimate, this machine's speed is at least 5 times as fast as my mac mini. Is there something that much be reset like the Macbook Air SMS resets (click on option function shift and power while the computer is plugged in and power off) Please HELP~~!!!
