Q: I am fairly new to MAC products and I just purchased a new iMac, which I love. I am doing well with it but am looking for some more detailed guidance and tips and tricks. Can anyone recommend any literature etc...

I should have added that David Pogue's 'Missing Manual' series is probably the best. I think he has already produced one for Mountain Lion.

Available from Amazon.
