Help, Guides, and News on making the Switch To Apple Macintosh Computers
March 2007 - Apple Mac OS Market Share at 6.08 Percent - Declines 4.7 percent since Feb 2007
Based on the data, the following observations can be made:
- Up 39.1 percent since March 2006
- Up 78.3 percent since March 2005
- Up 72.7 percent since April 2005 (Mac OS X Tiger launched April 29, 2005)
The 39 percent year-over-year increase for March 2007 has slowed coming in below the 48 percent growth observed in the first two months of 2007. The following is a view of Apple's Mac OS market share month by month for calender year 2007. Note that Net Applications splits Mac operating system data into two groups, Mac OS and MacIntel. MacIntel represents Intel builds of the Mac OS X operating system. The March 2007 data can be found here.
Observe that Mac OS comes in at 3.94 percent operating system share (down from Feb 2007's 4.29 percent) while MacIntel is reported to have 2.14 percent market share (up from Feb 2007's 2.09 percent). You can click on each image to get a larger view:
The March 2007 Mac OS data, representing PowerPC builds of Mac OS X continue to follow the declines first seen in the February 2007 data. The March data fell by 8.2 percent whereas the Febuary 2007 data fell by 1.2 percent. The reasons for the decline are unknown. Perhaps existing PowerPC-based Mac users are moving to new Intel-based Macs.
Mac OS X Intel Posts 2.4 Percent Increase from February 2007
The data shows that Mac OS X Intel experienced a 2.4 percent increase as it's share rose from 2.09 percent in February 2007 to 2.14 percent in March 2007. The increase was well below the 11.2 percent and 23.7 percent increases from the prior two months, February 2007 and January 2007 respectively.
The first two months of calendar 2007 showed strength in the overall Mac OS market share numbers but March 2007 put a halt to the increase. The drop in Mac OS market share is the first since June 2006 and comes at a time where many Mac users are waiting for the next release of Mac OS X, version 10.5 Leopard. The growth of Mac OS X Intel also slowed to the low single digits. The March 2007 numbers demonstrate that growth in the Mac user base has slowed. I expect this slowdown to be represented in Apple's second quarter 2007 earnings report.
What role if any is Microsoft Vista having on the Mac operating system market share? We'd like to see your comments. Note that Vista jumped to 2.04 percent in March 2007, up from February's 0.93 percent.
