描述

With macOS Monterey, the AppleIntelPIIXATA we use to restore PATA support broke. Because of this, numerous 2008 era Macs have lost support for their DVD drive when booted into Monterey.

Currently unknown where the issue lies, further investigation required.

研究方向
The root cause of the PATA driver failure on macOS Monterey is unknown. Begin by reviewing the AppleIntelPIIXATA kext source code (if available) and comparing its behavior between macOS Big Sur and Monterey. Check for I/O Kit changes that may affect the driver's initialization. Examine system logs (kernel.log) for any panic or error messages related to the kext. Consider testing with different SATA/PATA configurations. Further investigation should focus on identifying the exact incompatibility in the kernel extension.
