Mountain Lion Finally Becomes The Most Used Version of OS X

5 January 2013

Computerworld:

According to California-based Net Applications, OS X 10.8, better known as Mountain Lion, accounted for 32%, or nearly a third, of all Macs that went online during December. That was an increase of nearly three percentage points from November, when Mountain Lion powered just over 29% of all Macs.

Eventually, Apple will sell OS X upgrades for free and eliminate this problem entirely.
