"Cleaning up" an IMac
Are there ways to "clean" an IMac. I have had mine for a couple years now. Not a big computer guy. Just seems that it takes awhile for some things to open (Excel, Word, Internet sites, etc.). I get the colored wheel a lot. Wondering if I can do something to get it to run faster. I think I keep updated in things (at least what the computer prompts me to update).
IMac, Mac OS X (10.4.11)
