I downloaded a new copy of Lyx 2.0.1 and tried that - same result. Then I downloaded Lyx 2.0.0 again and tried that - same result. I downloaded the latest MacTex. TexShop works fine but Lyx 2.0.0 and 2.0.1 always fail immediately with the PowerPC error. Now I have checked Lyx properties (command I in the Mac finder) and the Finder thinks it is a Universal application. For comparison, Mail.app is an Intel application according to the Finder. Mark
