NetApplications shows Mac, Firefox gains
More than a sixth of all Macs are already running Mac OS X Snow Leopard in just over a month of use, new findings from NetApplications show. On September 29th, the one month anniversary of the release, about 18 percent of all Macs tracked by the stats firm were using some version of Snow Leopard, or 0.91 percent of all computers.
The data also represented a new high for Macs as a whole following NetApplications' revamped approach to calculating web stats, which it has said in the past more accurately reflect real-world market share and not just its website. Its share was 4.93 percent on the 29th but jumped to 5.12 percent for all of September, marking a new record for Apple's platform. The gain came largely at Microsoft's expense and dropped Windows' combined share to 92.77 percent, its lowest point in the past two years.
If relevant to reality, the figures would directly contradict assertions by Microsoft chief Steve Ballmer, who insisted that Windows was regaining share or at least remaining flat. The climate for PC buying is nonetheless expected to change when Windows 7 ships next month and much of the active resistance that stalled Vista sales is likely to clear.
Other platforms made little to no gain during the same month. Linux occupies third place with 0.95 percent, while iPhone OS grew slightly to 0.35 percent.
Web browser share was also a symbolic milestone and again hurt Microsoft the most. Internet Explorer's control fell below the two-thirds mark for the first time and lost nearly a percentage point to reach 65.97 percent of the market, most of which went to Firefox. The Mozilla browser gained almost as much as Microsoft lost and climbed the majority of a percentage point to an all-time best of 23.75 percent. Most of this is attributed to momentum for Firefox 3.5, whose share of all Firefox installs shot up 42 percent in a single month.
Apple also gained on the web in September as Safari reached a new peak of 4.24 percent of all web traffic. Google's Chrome (3.17 percent) and Opera (2.19 percent) also made advances.
