Notes

Start here

Encountered a boot loop when OpenCore started to load the installer until I fixed the USB map. I had done the USB map already, but had done something incorrect, so the installer didn't like it.

Eventually noticed that I wasn't getting OS updates pushed. This required adding revpatch=sbvmm to boot-args in config.plist.

Installing updates after 14.3.1 required setting SecureBootModel to Disabled in config.plist. This did not require a restart before starting the installer. It did require a restart after the install completed and the setting was reverted back to Default.

Post Sonoma 14.7, sleep stopped working completely. USB would partially shutdown (the StreamDeck would disconnect) and the display would power off. But, the system didn't sleep; it would stay awake. Had to add SSDT-GPRW.aml and an ACPI patch to fix this. From this bit of OpenCore Post-Install via this r/hackintosh thread.

Upgrade to Sequoia (15.x)

The upgrade process took a while, but that was only because I didn't realize that all I had to do was change SecureBootModel to Disabled and also the SMBIOS model to iMac19,1 to get the install completed. Those were the only meaningful changes needed. I did have to add three items to config.plist to satisfy the changes from OpenCore 0.9.5 to 1.0.4.

For updates, it will be necessary to change SecureBootModel and the SMBIOS model to iMac19,1.
