MAC is layer two and does not transition layer 3 boundaries ( routers ) steam may be able to use Mac as it is a local app so it can access the hardware layer, if a browser did that they would probably be brought before several dozen privacy commissioners.
Sites can grab user agent string, takes is and browser engine, sometimes platform ( but this can be spoofed ), Java ( this time by design ) can leak all sorts like resolution, have version, colour depth etc. Cookies can also be accessed. Using this and browser/plugin fingerprinting you can identify PCs quite well.
