I've seen some other people that have been having a failure to launch, but not like this. In fact, I downloaded a bunch of older builds and the only version I can get to start is 2.49 with python2.3.

Here's what I'm running on:
Model: iMac11,2, BootROM IM112.0057.B00, 2 processors, Intel Core i3, 3.2 GHz, 4 GB, SMC 1.64f5
Graphics: ATI Radeon HD 5670, ATI Radeon HD 5670, PCIe, 512 MB
OS Version: Mac OS X 10.6.8 (10K549)

I tried to get some more info by running Blender from the Terminal. Here's what I get:

[new-host:blender.app/Contents/MacOS] ryan% ./blender
ndof: 3Dx driver not found

The crash report window that pops up gives the following info. I don't know what any of it means.

Any clue what's happening here?
