this just started about a month or two ago where my imac will run like crap. I cant open more then three things without it running super slow it crashes safari and firefox all the time. cant watch a youtube video, it always seems like its buffering. cant look at my pics on this thing because it just runs and runs and runs when it stops ill move the mouse a little and it starts running again. ( the little time icon come on) anyway if this is something that someone knows about please let me know the fix. thanks in advance.
