Optical drive not recognized in 10.6 but works when booted in 10.5
I have a Macbook A1181 with Snow Leopoard installed. The optical drive is not recognized in the OS, but I can boot from it. In fact, I installed another hard drive, installed a new OS (10.5) and the drive is recognized. I have also installed another optical drive with the same results.
I ran the Software Update in 10.6, but no change.
It looks like there is a software problem in the OS. How can I fix the software to recognize the optical drive?
