I'm running SheepShaver on my Intel MBP so that I can emulate OS 9.0.4 (SS doesn't work with versions after that). I used an OS 9 disk image that came as an iMac restore disk, so the software is specific to that hardware, which is causing some minor problems with the emulation. The OS boots up fine in SheepShaver and I can run applications, but there was no sound, and trying to access the sound control panel gave me an error. I installed update 9.0.4 from Apple's website and that gave me access to the control panel, but there is no "built-in" device listed in the sound output area for me to select - hence the continuing lack of sound. Does anyone happen to have a disk image of OS 9.0 (or 8.0), that didn't come with a specific computer? I'm pretty sure that will fix the issue.
