Hello I was using Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina on my HP620 wihout problems but since it is outdated and discontinued so it was hard for me to use other newest apps. as they dont support old MacOS,
anyways
I upgraded to Big Sur and it installed everything and then I got my Big Sur log in screen however I get no keyboard and mouse, it seems like the USB ports are not configured yet, I do have USBv2 and USBv3 physical ports but none of them working I guess.. I also tried use PS/2 mouse but it won't recognize on macos
and I tried to research to resolve this problem and this is what I found so far to fix this problem, not sure because I haven't tested it because I dont know what they are saying (see the picure below). I think they are using some app to make XhciPortLimit to False, so.. I wish I know that program name so I can do the same, I really need this hacktosh working because it has all of my important work data and my saves from life events.
Please help
Thanks!
EDIT: I'm using OpenCore
