I know, I may be stepping into murky waters here... I own several PC's and a MAC. Despite the claims of Apple folks, MAC's get clogged up with gunk just like PC's. I have successfully used Ray's programs and guidance found here, to maintain my PC's and those of my family. Oh, and my 10 year old PC, running XP is humming along quite nicely, by the way - thank you very much! Does anybody here know of a site similar to this that offers unbiased, good information for fixing and maintaining a MAC?
