Unable to initailize hardware accelerated OGL on Mac-?Oni

Have the Oni demo- works great on the other systems- except one system keeps giving me the error:
Unable to initialize hardware accelerated Open GL on your system with the current settings.

Anyone know what settings???-
(on a Mac, that is)

same problem with Q3 on iMac; “couldn’t initialize OpenGL”
