I have a 2009 Mac Mini with a duo core intel (2Gz) 1GB memory. I am not a very technical person so not sure if that is all of the info that maybe needed for my question but it is what I got off the computer itself. Anyway in the last few weeks the "spinning wheel" is popping up more and more and it is very slow at times to respond to a mouse click. It was suggested to me that over the 4 years that I have owned it that I have about "over loaded" it with accumulated data that really isn't needed. Not sure how I go about finding out how much data is stored or if there is someother sort of problem causing these symtoms? Also is there anyway of clearing unneeded data? Like I said maybe a foolish questions but would appreciate any input.
