I used to provide yearly stats on this site that showed Browsers, Operating System and Screen Resolution. Somewhere along the way, about 2006, I lost interest or got too busy to publish them. Over the last year or so I have noticed a big increase in Mac usage, every man and his dog has one, or so it seems. So I had a quick look at the stats for last month and compared it with the old stats. In 2006 mac users accounted for just 2.1% of visitors. Currently November 2009 they account for 12.49% that's over 10% increase, a significant amount of market share going to Mac.
