"My MacBook," is a good book for reference after your telephone support is gone and you need to read about "how to's" and have the computer in front of you. My husband has a very hard time reading from the Apple support page and then coming back to his machine to actually do what it said. With this book he can have the instructions right there.  This book is designed for basic Mac skills. I would have liked to se a few more intermediate skills in it.
