Net Applications: Apple’s Mac ‘market share’ declines slightly to 6.08% in March 2007

“Although up 39 Percent from March 2006, Mac OS market share as measured by market research firm Net Applications (Market Share) shows that Mac OS market share declined by 4.7 percent in March 2007. The total Mac OS X market share percentage for March 2007 comes in at 6.08 percent [vs. 6.38% in February]. The decline is the first monthly drop since June 2006,” Switch To A Mac reports.

Percent Increases
• 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)

Switch To A Mac reports, “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… 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… 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).”

“Note that Vista jumped to 2.04 percent in March 2007, up from February’s 0.93 percent,” Switch To A Mac reports.

MacDailyNews Note: Last year showed very slight increase (basically flat) in Mac “market share” from February (4.31%) to March (4.37%) 2006. In 2005, February clocked in at 3.37% vs. March’s 3.41%. This is likely a seasonal occurrence. One month does not a trend make.

  1. Probably more likely due to anticipation of product line refresh within the next few months. Anyone holding back for the quad core? Multitouch monitor possibilities? Thinner iMac?

  2. Maybe what Apple should do is start selling Macs with technology from 3 years ago and call them “Leopard Capable,” then offer us vouchers to get Leopard once it comes out.

    Funny thing would be is that Leopard would run without a hiccup on 3 year old hardware!

  3. Many of us are waiting for Leopard. I am waiting to buy a new server as well as a new notebook. Perhaps this is true across the board – certainly among existing Mac users.

    Q: When an existing Mac user upgrades to a new Mac, what happens to his or her old Mac? Does it end up on eBay? Will it be bought by a switcher looking for a low-risk way to learn about Apple? The high resale value for Macs suggest that there is quite a demand for used ones.

    So would it be true to say that significant sales of Intel/Leopard Macs to the Mac community can be expected to create lots more new mac users via the used mac market?

  4. Yeah. I totally agree with the guys above. I know a few people waiting for leopard.

    If Apple put a voucher in their current stock of Macs for a free Leopard upgrade then the market share figures would have risen. It makes sense.

  5. This is the percentage of people browsing websites, so small increases in anticipation of Leopard don’t make sense. If people are waiting to upgrade, this will not impact these stats at all. These are cumulative measures of the amount of time people are using Macs to surf the web. Upgrading a machine wouldn’t increase this number unless a new Mac person bought your old one. This number correlates with how many Macs are being used right now.

    On a similar note of small market share, currently, a small percentage of distributed computing is done by Macs – somewhere on the order of 2.6%. I know the number of Macs out there is higher than that (this article mentions 6 percent), so let’s show them that we are not as stingy as we currently appear to be.

    Presumably people put off buying PCs until Vista was released. When they bought new PCs their old ones presumably got handed down to someone else, increasing market share for Windows, and decreasing share for Mac…
