Still doesn't work, clean install of snow leopard (10.6) on Gigabyte EX58-UD5 board (using the installer script over on insanely mac) with Gigabyte factory overclocked GTX 260 (dvi-vga-hdmi). Followed the guide completely (Not scared of terminal, I live and breath nix), even tried editing the NVresman plist by adding the dev id's. No res, no qe/ci/opencl - i.e no translucent menu bar, jerky screensaver.

I'm at my wits end now, I've tried the GT2XX driver from nvidia and the plists. The trouble is, people who have it working aren't letting us know what their setup is so we can try and work out why other setups don't work correctly. It's all well and good saying, THIS IS WORKING!! WOO HOO! We need to know why.

I'm not giving up with this card. It's got so much potential in SL.
