As they pretty much have always done. Apple’s concern in-terms of the pro market is not 3D software it’s video and audio because that makes up a significant amount their users. I would love it if Apple catered to 3D creators as well, but 3D in general is a very niche market and is probably not really as lucrative as the other two. Like no one is going to go out to buy a Mac just to do 3D work even if Apple had the best hardware or the best OpenGL implementation on the market. Definitely not at the same numbers as audio/video professionals would.
