OS X 10.8 Mountain Lion Tops Lion as Most Popular Mac Operating System

According to Web analytics firm Net Applications (via Computerworld) Apple's OS X Mountain Lion is now the most popular version of OS X, just five months after its July 2012 release.

During December, 32% of all Macs that went online were running OS X 10.8 Mountain Lion. Usage of Lion, the previous iteration of OS X, dropped from 30% to 28%.


OS X 10.6 Snow Leopard, first introduced in 2009, remains widely used despite its age. As of December 31, it still represented 29% of Mac Internet usage. Snow Leopard remains for sale on the online Apple Store and has been lauded for its stability.

Easily accessible and reasonably priced upgrades have always enticed Apple users to embrace operating system updates. Apple famously boasted about selling a million copies of OS X 10.7 Lion in its first day of availability, and Mountain Lion also saw rapid adoption numbers.

Not a fan of this yearly desktop OS update. Devs are taking long to update their apps for the latest OS; by the time they do update, Apple announces a beta of the next version of OS X. (I'm not blaming Devs - I can't imagine them wanting to support multiple OSes within such a short timeframe)

I'm not saying pull a oldschool Microsoft and go 5 years between releases, but a 18-24 month schedule seems easier on consumers and Devs.

Wonder how many Lion users would have stuck with Snow Leopard if it had iCloud support.

LOL Lion is now less popular than Snow Leopard despite being newer. Kind of like the relationship between Windows Vista and XP.

Despite OS X versions becoming worse every time, people are still buying them without any exceptions. This ain't gonna make Apple work harder is it!

Okay exception is Mountain Lion: they learnt from their awful, horrible, silly, stupid mistakes in Lion and fixed most of them. But it's still not as good as Snow Leopard was at the time.

I really hope they stop releasing operating systems every year and instead concentrate on reducing the number of stupid features and making a solid, stable, reliable system with a focus on consistency, like it used to be with Leopard and Snow Leopard.

Almost a year into ML, and messages is still out of order, SMB is clunky, blah blah.

It may be the most popular (only by force) but it is FAR from their best.

SL FTW
