Is there any way to speed up a MAC without having to hire a tech whiz and pay top dollar for hard ware and a service call? This is what my dad called to ask me a couple days ago. He uses his MAC a lot but reported that it keeps running slower and slower, even freezing up at times, and not displaying all his program materials like graphics OK as normal. He said my mac is running slow! So I took pity and asked a college tech professor for help nearby (he's my neighbor). He sent the link above.
