macOS Sonoma on an
AMD Ryzen 5625U (Zen 3 architecture) requires specific
SSDT-CPUR.aml patches and kernel updates to function correctly. The standard
AMD_Vanilla patches from GitHub must be updated to the latest version supporting Sonoma, which includes
22 kernel patches compared to the 16 used for Monterey.
Key configuration steps include:
- SSDT-CPUR.aml: You must generate and install this file to handle CPU power management and core mapping for the 5625U.
- Kernel Patches: Ensure the config.plist uses the latest patches from the AMD-OSX/AMD_Vanilla repository, specifically enabling the Shaneee mtrr_update_action patch while disabling the older algrey version.
- Boot Arguments: Add agdpmod=pikera to boot-args to resolve potential black screen issues with AMD Radeon graphics, and consider revblock=media if using RestrictEvents.kext.
- Secure Boot: Set Misc > Security > SecureBootModel to Disabled if installation or updates fail due to Secure Boot restrictions.
