Where to find a statistics on different Mac OS X version distribution [duplicate]

Question

I found this post having statistics for the different OS X version distribution from April 2013: http://chitika.com/os-x-version-distribution

Does anyone knows a newer statistic on this topic? I was not able to find anything using Google.

Answer 1

Some of the larger OS X software vendors generate statistics from their update mechanisms.
E.g. the Omni Group provides this web page: http://update.omnigroup.com

You can switch to "Overall, major" to see a graph describing the adoption rate of major OS X versions.
