Windows 10 is installed on 24.5% of devices
-- but that's only half the story. "Apple's Mac share of personal computers worldwide fell to a five-year low in December," reports Computerworld, adding that Linux and Windows "both benefited, with increases of around a half percentage point during 2016."
An anonymous reader quotes their report:
According to web analytics vendor Net Applications, Apple's desktop and notebook operating system -- formerly OS X, now macOS -- powered just 6.1% of all personal computers last month, down from 7% a year ago and a peak of 9.6% as recently as April 2016... The Mac's 6.1% user share in December was the lowest mark recorded by Net Applications since August 2011, more than five years ago... In October, the company reported sales of 4.9 million Macs for the September quarter, a 14% year-over-year decline and the fourth straight quarterly downturn. Apple's sales slide during the past 12 months has been steeper than for the personal computer industry as a whole, according to industry researchers from IDC and Gartner, a 180-degree shift from the prior 30 or so quarters, when the Mac's growth rate repeatedly beat the business average.
Apple's success through 2016 was "fueled by Microsoft's stumbles with Windows 8 and a race-to-the-bottom mentality among rival OEMs," according to the article, which also notes that the user share for Linux exceeded 2% in June, and reached 2.3% by November.
