Finally, A detailed history of the Mac OS

I own a great book, Apple Confidential 2.0, and it is a great resource for the whole history of Apple.

But, I have yet to see an online resource of each version of Apple’s OS, until today. History of Mac OS is a great and informative article of the versions of System and Mac OS. So, if you are interested, go to amacgenius.com and read about the history of our favorite OS.
