First of all, I tried with VMM enabled, but my config doesn't even boot with VMM, so NOT USING VMM in my case.
Dropped
AGPM-Override.kext to \EFI\OC\Kexts on my OC (EFI) partition.
Added the following to config.plist as the last DICT section in Kernel key (below FeatureUnlock.kext in my case):
Code:
<dict>
<key>Arch</key>
<string>x86_64</string>
<key>BundlePath</key>
<string>ASPP-Override.kext</string>
<key>Comment</key>
<string>ACPI_SMC_PlatformPlugin Override</string>
<key>Enabled</key>
<true/>
<key>ExecutablePath</key>
<string></string>
<key>MaxKernel</key>
<string></string>
<key>MinKernel</key>
<string>21.4.0</string>
<key>PlistPath</key>
<string>Contents/Info.plist</string>
</dict>
Rebooted and applied the update. Worked automatically, most probably because I got:
Code:
<key>ProtocolOverrides</key>
<dict>
<key>AppleBootPolicy</key>
<true/>
and
Code:
<key>Quirks</key>
<dict>
<key>RequestBootVarRouting</key>
<true/>
...however I believe most people do anyway.
