In addition, 50 percent of the 3.9 million Web visits to Forrester.com from May 2012 to Jan. 2013 came from machines running Windows 7. Windows XP was a distant second at 22.3 percent.
More Macs Emerge With BYOD
It's worth noting that the aforementioned 7.2 percent Mac OS number tells merely part of the Apple enterprise story. Why? Because that percentage includes only company-issued Macs and doesn't take BYOD into account.
To verify a bring-your-own Mac presence in the enterprise, Forrester noted in its report that Mac OS traffic on Forrester.com has increased from 8.7 percent of web visits in May 2010 to 14.6 percent today. In a separate Forrester survey that examines the technology and behaviors of employees, 14.3 percent of information workers globally say they are using a personally owned Mac for their work in a typical week.
"The gap between IT support on one hand and employee web traffic and self-reported ownership on the other indicates a strong Mac BYO presence," writes Gownder.
Mobile OSes on the Verge
PC operating systems are a still a majority, but a shrinking one, as mobile devices take on a legitimate role in the enterprise.
While 92.9 percent of Forrester's web visitors are coming from PC operating systems, the remaining 7 percent of web traffic is coming from mobile devices. Of that 7 percent, 5.6 percent is from iOS devices (iPhone and iPad), 1.2 percent is from Android devices, 0.2 percent is from BlackBerry and 0.1 percent is from Windows 8/Windows Phone devices.
Forrester reports that more than 400 million iOS devices sold worldwide by mid-2012 and at least 100 million of those were iPads.
"The reach of these devices is vast and growing," writes Gownder. "Global information workers have eagerly adopted iOS devices, as 25 percent report using personally owned iPhones and 18 percent report using personally owned iPads for their work."
