You're missing the SSDT-HPET that comes from SSDTTime, and the patches to resolveThanks for replying, same error I was getting even before installing Catalina with clover bootloader. As I always stuck and need to wait at this screen, that is why I installed it with the clover bootloader. For further reference, I am attaching my opencore config files. If you find anything wrong that is causing this error, please let me know, it will be really appreciated.
IRQ conflicts that also come from SSDTTime. I found it easiest to generate them from
downloading and running CorpNewt's SSDTTime under Windows 10 on the same machine.
I'll attach my version of the SSDT-HPET and the accompanying changes to the config.plist
in the small attached zip files. You'll need to manually incorporate these changes in your
config.plist and install the SSDT-HPET in your ACPI folder. Be forewarned, however, that
these were generated on an 8300 with my settings, and your mileage may vary. It is best
if you generate your own using SSDTTime.
In addition, I would suggest that you set the Nvidia to be the primary in BIOS and your
IGPU to secondary, and that you delete the section in your config.plist for defining the
AAPL,ig-platform-id of PciRoot(0x0)/Pci(0x02,0x0). Whatevergreen will figure out the
ig-platform-id and set it to the default 07006201. If you're going to manually set it,
you may also have to manually set the device-id to 52010000 (for HD2500 graphics).
Let Whatevergreen take care of it instead.
In addition some versions of USB-Injectall don't work with the legacy hubs very well.
Try using this USBports.kext for iMac13,2 instead and remove Injectall.
