Typically, the set of browsers to be agreed with the client, but I then decided to stir up your own project. And I would like to fit the widest range of potential visitors. Win browsers, I understand everything, but on other platforms as it is not really. One and a half hour run on the ratings gave only partial clarity, for example, on macOS. There is a constant "four" - safari, chrome, opera, firefox. But still flashed in different combinations a large number of other browsers. And to find the prevalence of browsers in percentage (for macOS) failed. Test on dozens of browsers as you do not want, so my question is: which browsers should be considered when the layout, and what you can score? Interested in platform macOS, iOS, Andriod, Linux.
