Got mail form Nvidia.. Here's what they sad:
Hello Hans Martin,
Thank you for contacting NVIDIA Customer Care.
I understand that you have a GeForce 8600M GT graphics card in your Apple notebook. You are having difficulty in playing the game Age of Empires 2. You get a message to ensure that the card and the driver are compatible with Direct Draw.
The GeForce 8600M GT is Direct Draw compatible. However please note that, we provide the basic chipsets to Apple, and Apple custom build the graphics cards to suite a particular model of Notebook. Also, the display drivers for Apple notebook GPU's are custom made for the notebook make and model they are used in to support some of the hot plug n play features your notebook supports. For this reason, the desktop Forceware display drivers, which are available on our web site, will not work on your notebook. For these reasons, we do not know the features enabled and options available with an Apple graphics card or its driver.
Please contact Apple for assistance on the issue you have.
Please feel free to contact us for any further clarifications.
Regards,
NVIDIA Customer Care
