[macOS Catalina] No graphic acceleration

Hi,

Yesterday I updated to Catilina from Mojave. Now I have no audio (but it seems to be an AppleALC issue) neither graphic acceleration. I have an Intel HD620 that works perfectly under Mojave. I have done no changes on EFI configuration, I have only upgraded Clover to Beta version and kext. The ig-platform-id is still 0x59160000...

Thank you in advance.

(By the way, do you know any 64bit wireless utility for a Ralink wi-fi adapter?)
