this past week i have noticed my mac has become very slow. i have a 24 imac (maxed out specs) the keyboard lags a ton when typing (i tried replacing batteries) spotlight somtimes doesnt pop up when i click on it everything seems to just be going slower. (apps that dont rely on the internet fyi)i know this is nitpicking but i maxed everything out and spent a lot of money so i wouldnt have to deal with this. i do have bootcamp but i havent used it in about a month. Furtheremore, i have a friend with the same exact computer and he doesnt have windows and he's experiencing similiar problems. is there spyware on osx that im not aware of?
