I have an Intel iMac with a 2 ghz processor, 250 gb hard drive, 1 gig of ram and a 20 inch screen. It is not runny nearly as fast as it did when I first got it and I think it's because of things taking up space on my hard drive which has only 87 gigs free
. The problem is i don't know what is taking up all that space
and i was wondering if there is a program that can show me. Thanks.
