“Mac OS X 10.8.x, known as Mountain Lion and the current release of the operating system, has accounted for a majority share of the web traffic from Macs for the first time, according to new figures from web statistics firm Net Marketshare,” MacNN reports.

“The crowning comes just five months after the release of Mountain Lion, and took about half the time it took Lion (10.7) to take the lead position away from Snow Leopard (10.6) as the most popular version of OS X,” MacNN reports. “Snow Leopard is still the second-most popular OS X version installed, with just under 30 percent of the base compared to Mountain Lion’s 32 percent; Lion is now in third with 29 percent.”

MacNN reports, “Earlier versions of OS X such as Leopard (10.5) and Tiger (10.4) have fallen to insignificant percentages, with Leopard around eight percent and Tiger around two percent.”
