Apple’s latest desktop operating system, OS X 10.8 Mountain Lion, launched just over a month ago, but its usage is spreading like a raging forest fire. 48 hours after its release the OS was already running on 3.2% of all Macs, but new data is showing that 10% of all Mac users are now running Mountain Lion on their machines.
Chitika has been tracking the adoption of Mountain Lion via their ad network, and says that the usage of Mountain Lion has been increasing steadily with no sign of letting up. The new OS is on track to outpace OS X Lion, which took three months to gain 14% use on all Macs.
Based on current trending, OS X Mountain Lion should hit the 14% mark within the next three weeks, unless something crazy happens that causes it to plateau. The faster adoption may be attributed to the generally more positive reviews that Mountain Lion received over Lion.
Chitika also released statistics for the current usage of all versions of OS X. As of August 2012, Snow Leopard commands a 43.28% share, while Lion comes in at second with 31.48%. With a 13.09%, Leopard is still used more than Mountain Lion, and 2.5% of Mac users are stuck in a sad place where they still have to use OS X 10.4 Tiger.
