According to the latest market share survey from NetMarketShare, the market share for both Mac OS X and iOS declined in May.
According to the report, among desktop operating systems, Mac OS X had 8.52% of the global market share in May, down from 9.2% percent in April (that’s global market share; in the US it’s over 13%). April’s 9.2% was an all-time high, according to NetMarketShare’s measurements. Windows remains dominant with 89.69% as of May.
iOS had 23.10% of the mobile operating system market share in May, down from 28.62% in April. This compares to 70.85% for Android, 2.57% for Windows Phone, and 1.50% for Java ME. The all-time high for iOS was in July 2012 with 65.94%
NetMarketShares’ monthly surveys don’t measure market share in terms of computer systems sold. Instead they sample data from visitors to some 40,000 web sites operated by their clients. And note that NetMarketShare’s numbers don’t equate to sales.
