OS X Yosemite - the missing manual (by David Pogue)
- The book that should have been in the box.
It takes me more than a week to complete this 800+ pages English book in my spare time but it is all worthy because now I have a comprehensive understanding on Mac OS. And this will make my life easy and beautiful since my career is computer related and I use computer 8+ hours a day in average.
The general comment after reading this book is: OS X is an amazing mature operation system and I even regret not to have my first Macbook before my thirty.
