Hello. I got my 2010 Mac Mini like 4 days ago , And you can see the spec on my signature... Now the thing is that i got 4GB Ram, And lately it happens a lot that the computer is just using RAM For nothing. For example if i go to the Activity monitor i can see there's only 1GB Ram and 3GB Ram is used. Now i really don't understand on what. Everything open me for me is the Google Chrome browser. And even if i close it it changes only a little. and i can actually feel the Mac OSX Is being slower... I wonder what wouldn't upgrade my Mac Mini and i would stuck with 2GB Ram. Another issue i'm having is with the Magic Mouse, Lately it just becomes very very slow and i have to re-connect it to work fast as normal. Does anyone have any ideas why is it happening? Thank you very much.
