I'm confused .... This are steps I have followed to install Catalina, and upgrade to Big Sur on my T440p. Only this





Nothing about this



I just have used your EFI folder ....




How can I update to last OpenCore and kexts? I need audio etc

PD: Now looking on help-me-understand-how-to-upgrade-opencore

the idea is to install Catalina first and then do the USB setup as XhciPortLimit is broken in later versions of macOS


you can use hackintool to scan and download kexts or go to the github to download the latest kexts

Yes, I understand the idea. I used it on my Mojave, but it works for me on Catalina without setup XhciPortLimit ...

either way, you need to do the usb setup correctly for a functional machine

Do I need it after or before upgrade to Monterey ?
Now I have configured network over Catalina and trying to download Monterey from Apple, But it says not available.

Also trying to download recovery full install from, but not available ...
What I'm doing wrong?
Thanks

If you are already on Catalina, then you really must do the usb port setup as mentioned at the top of the guide in post 1

then you can upgrade to Monterey

Yes but how can I get the installer?
PD: I'm over Big Sur updated from Catalina.
