WOAH not a reply here but I read this post and I too am new to Mac's . My first one was this past Christmas 2011 gift . Please inform me of what type of maintenance I should do and how often .
I am a 54 year old guy with graying hair and yet I am like a 17 year old blonde getting her first car. I just open the Mac and start going. Never thinking of any maintenance I may need.

Thank you all;
