OS X 10.9 Mavericks Adoption Continues to Grow Steadily
OS X 10.9 Mavericks continues to gain popularity, overtaking previous versions of OS X like Mountain Lion and Lion in November of 2013 according to the newest market share data from Net Applications (via The Next Web). First introduced on October 22, Mavericks is Apple's newest operating system and the first version of OS X to be released free to consumers.
During the month of November, Mavericks gained 1.58 percentage points, growing from 0.84 percent of total operating system market share to 2.42 percent, while other versions of OS X lost share. OS X 10.8 Mountain Lion dropped 1.48 percentage points to 1.85 percent, while OS X 10.7 Lion dropped 0.22 percentage points to 1.34 percentage points. OS X 10.6 Snow Leopard dropped 0.07 percentage points to 1.53 percent and OS X 10.5 dropped 0.01 percentage points to 0.32 percent.

Though Mavericks market share has continued to grow steadily since its release, overall OS X market share, at 7.56 percent, remains dwarfed by Windows market share, which is at 90.88 percent with Windows 7 being the most popular Windows operating system.
While Net Applications data shows Mavericks gaining ground over its predecessors, data from GoSquared suggests that though Mavericks usage has continued to rise over the course of the last month, it is still lagging behind OS X 10.8 and OS X 10.7. According to the data, Mavericks usage is at nearly 21 percent, compared to 31 percent for 10.8 and 24 percent for 10.7.
The difference between the two measurements is likely due to the number of visitors tracked and the different sites being monitored, but both data points suggest that Apple's strategy of delivering the update free to all users has worked favorably for the company, encouraging users to upgrade to the latest software.
