ThinkPad E480 - Catalina/Big Sur Boot issues (OpenCore)

Rafael Siqueira

Recommended Posts



I'm trying to boot and install Catalina (or Big Sur) but I'm facing a boot error that's not so clear to me. The message "can't perform kext scan" is not helping much.


The bootable usb was created based on this repo: https://github.com/SukkaW/ThinkPad-E480-Hackintosh. I've made small changes to enable some debug message.


My hardware is almost the same (without the manual changes).

You've got lots and lots of patched SSDTs + ACPI patches. Then some of your Quirks are incorrect. You should try with the minimum but set of parameters recommended for Kaby Lake or Coffee Lake laptops at Dortania. With regards to the property injection you've configured for UHD620, all looked Ok except the injected ig-platform-id and I can't help thinking it should be 09005916.
