Mac market share cratered around the turn of the century as result of a stagnating operating system (MacOS 9) and then use of uncompetitive PowerPC processors. Since OS X and the switch to x64 processors they've been slowly crawling their way back, but they still don't even have the market share they did in the mid 90s. And the OEM licensing never much affected Apple to begin with since they make their own hardware.
