Hi All, At my school a student brought a new unibody MacBook, and we have an image that all the computers use loaded with specific settings, books, documents, etc. But our image is a Leopard image. We tried the image on the new MacBook that comes with Snow Leopard pre-installed, and it went smoothly, everything seems to be working perfectly fine except: No audio devices found and also I can't adjust the brightness of the screen. Really an truly the student doesn't care about the brightness, we're all more concerned about the no audio. We ran all software updates to make sure there weren't any EFI updates and there weren't any but we went ahead and updated everything else. Same thing. I know the sound works cause I booted to an external with Snow Leopard and there's sound. So is there any way of getting those audio drivers from Snow Leopard into Leopard?
