E-Maculation

I recently upgraded to El Capitan from Mountain Lion on my early 2008 Mac Pro.

At first, all went well. Sheep Shaver launched without incident. A couple days later it started crashing on launch if another program was running, and then it failed altogether. It acts as if it can't find a ROM file.

I've rebuilt it from scratch a couple times, and there's nothing doing.

How do I fix this thing?

Thanks,

Trevor Monroe
