“Mountain Lion, also known as OS X 10.8, accounted for 25.8% of all Mac operating systems during October, according to statistics from metrics company Net Applications.

Since Mountain Lion’s debut, Snow Leopard has lost 6.6 percentage points, a drop of 17%. Meanwhile, Lion has lost more than double that — 15.6 percentage points — falling 33% since July.”
