Well...no. Not sure why you'd say that; I don't think anyone is expecting quad SLI setups in iMacs or anything.
Hence the question "who defines serious about gaming"
Yes, since it's up to Apple to provide the technology that developers actually use. Nobody is saying that it's Apple's job to make the games.
The technology is there for them to use. SDK's, xCode, etc, they have it, THEY don't have skilled programers to write the code.
Because Apple is lagging behind in the driver department.
It
could happen if they spent a little time on the problem. Hence, it's Apple's job.
NVidiea and ATI drivers are written BY those respective companies in CONJUNCTION with Apple developers. It's BOTH parties problem. You want to put the sole blame and responsibility on Apple then be my guest. It's ALL parties involved.
If you petition one, you need to petition them ALL. EA is getting back on board, Aspyr has been doing it for a while, there are several companies on board. Your few attempts at contradicting me aren't working. It's everyones job to get games to the Mac. Not just Apple. The tools are out there, most game companies don't want to or for lack of experience can't code for Mac simply because they've been used to coding for Windows.
It's like telling an VB programmer to he has to now write C++. It takes time to learn how to do. I write code for several platforms and it's taken me 10yrs to get to this way. Apple has it's part to do yes. I'm not saying they don't but you can't put the sole blame ON Apple. The video game programmers and companies on a whole need to get THEIR act together and start learning how to program and invest some money (the REAL factor in video game development) up front to get their developers to learn how to write games effectively for the OSX system.
