What Safari version is Google Analytics referring to?

Question

Thanks to this question, I was able to find the Safari version for most of the Webkits (all the 3 digit Webkits) that Google Analytics refers to. However, there are a few that are not listed in the Wikipedia entry.

Here is a snapshot of what Analytics is showing me.

What version/OS of Safari do the 7534 and 6533 Webkits refer to?

1.  7534.48.3   45.50%  
2.  534.57.2    12.51%
3.  534.55.3    8.44%
4.  533.22.3    6.60%
5.  534.52.7    4.96%
6.  6533.18.5   4.95%

Answer 1

The first digit corresponds to the version of OSX that the webkit was built for.

6533.18.5 would be for Mac OS X v10.6 "Snow Leopard"

7534.48.3 would be for Mac OS X v10.7 "Lion"

If you have one that starts with an 8 and four digits would be Mac OS X v10.8 "Mountain Lion"

etc.

Answer 2

I think Google Analytics added an extra number in front of the version number. IMO 7534.48.3 refers to 534.48.3 and 6533.18.5 to 533.18.5.

These 2 versions are respectively Safari 5.1 and 5.0.2, which makes sense in regard to their market share.

You could try contacting them through Google Analytics Forum.
