I'm close to give away and cry because I study and study and nothing works...
Guys, I've installed with sucess the vanila catalina on my acer aspire E5-571 but my usb wifi adapter doesn't work and I can't imagine why it's happening.
It just doesn't work even if all properly kexts is installed in the correct place(all kexts in this case is USBInjectAll and XHCI-unsupported).
And more a problem, the OCC(Open Core Configurator) can't read the config.plist. My bootloader(in this the name?) is clover.
I was watching the video below and it didn't helped me
