Not sure if it is specifically California because it does seems majority of US Tech sector, especially those doing Web Development uses MacOS.

But your comment does echo the some point many have repeatedly posted on HN, in Europe most of their colleagues are on Windows. ( Although some people mention UK having higher Mac concentration ) And Mac is an absolute minority, even within the tech sector.

But I have been saying for some time, at the current rate things are going I would not be surprised if Microsoft start to open source a portion of Windows. And the pendulum may swing to their favour once they have captured more of the Cloud and Enterprise revenue.
