Hi, I know this is not the best forum to ask Mac question but I am a bit lazy registering elsewhere, besides I believe there is lots of Mac users here I have found no way running any OpenGL on my mac mini with HD3000 and Lion. I just wonder is it still OS/drivers problem or my mini is damaged I have bought it second hand so I do not even know if I am eligible free apple support. Has anybody run "Gravity" or "Marble Arena 2" on Sandy Bridge graphic (HD3000)? I have got only screen flicker and a message in the system log "1/15/12 10:15:06.161 PM [0x0-0x1e01e].com.slowchop.gravit: SDL_SetVideoMode failed: Failed creating OpenGL pixel format" etc. Thanks for little help!
