My system:

Mac OSX 10.2.3
733MHz Power PC G4
1.5 GB RAM

I just installed a new:
ATI Radeon 8500 for Mac 64Mb/AGP/Video Card

I have two monitors running off the card.

When I try to play “Return to Castle Wolfenstein” I get these error messages.

“aglChoosePixelFormat failed”
“Couldn’t start OpenGL”

When I try to play “Tony Hawk Pro Skater 2” I get a black screen with only the cursor arrow showing.

The older card that came with the Mac worked just fine, however I needed to run two monitors for my business and since installing the new card the games won’t work. PLEASE HELP!

Ask on the Apple or ATI support forums. This isn’t really the place for the question, and you’re highly unlikely to get an answer.
