Yeah, we do prioritize Mac disproportionately to its market share for that reason. It does sometimes happen that we have to make hard calls though, and that's what Jeff is referring to.

On that note, one of the key motivators behind WebRender (our new graphics backend) is that it provides hardware acceleration across all platforms, including mac (whereas our current Direct2D acceleration works only on Windows). So Mac graphics performance should generally improve once we get that shipped.
