#1 Re: Support » Error: Mac OS X - Couldn't create OpenGL pixel format for video output » 2008-08-31 02:11:05

I ran opengl extensions viewer for mac os x, it says that I'm at 100% for opengl 1.1 thru 2.1 but also says that I'm using Apple Software Renderer (and not NVidia)

Renderer: Apple Software Renderer
Vendor: Apple Computer, Inc.
Memory: 0 MB
Version: 2.1 APPLE
Shading language version: 1.20
Max number of light sources: 8
Max viewport size: 16384 x 16384
Max texture size: 16384 x 16384
Max anisotropy: 0
Max samples: 0
Max draw buffers: 4
Max texture coordinates: 8
Max vertex texture image units: 16

I'm confused about the 0 MB, I have a 512MB card.

I'll try looking for a more recent driver for my card (nvidia 8600 GT 512MB)

Do you have any suggestions of (free) opengl software to test on?

I have read the README and README.MAC in /Applications/

I have Mac OS X 10.5.4, 2.2 GHz intel core 2 due, 4 gb memory, 512 MB Nvidia

When I try to start DeSmuME application, the error message 'Couldn't create OpenGL pixel format for video output' appears in a message box. I click ok, and can load rom but see nothing. I can hear sound so I know the rom loaded.

I am using whatever OpenGL is built in to mac os x. I downloaded the latest SDL (SDL version 1.2.13 (stable)) for Mac os X and put the Framework in /Library/Frameworks

I can hear sound but no video.

Can anyone tell me what I am doing wrong?



EDIT: I am using a non-apple old display due to a problem. It is a 3 yr old 15 inch LCD display, and About This Mac says that this display is not Quartz Enabled. Perhaps I need to get better hardware (display) or is this a software problem?
