What's the problem exactly?
When running Second Life on an affected MacBook Pro, your machine completely freezes up. The cursor doesn't move, pressing the Caps Lock key does not change the Caps Lock light and your machine is no longer reachable from any other machine on the network. The only means available to recover is to hold the power button down until the Mac powers off and then restart it.
The solution they give requires a download and install of the OpenGL Profiler which will then tell your Mac to run the SL client with a different rendering driver (one made for ATI cards, not Nvidia). I will have to check with ITS to see if this is even a possible solution that they might have me pursue. If you are having problems like this please let me know at afontan @ bgsu. edu.
