Keyboard Issue Tahoe

Yesterday I successfully installed macOS Tahoe on my iMac 27 end 2015 with installed OpenCore 2.4.1.

I did it through System Preferences. Maybe that was the big mistake.

The installation went smoothly, and the system boots up quickly without any issues.

However, I’ve run into a major problem: my USB keyboard is not working at all. I’ve already tried multiple keyboards, also wired ones, but none of them are recognized, so I can’t even log into the system.

Did I install the system too early? Is OpenCore 2.4.1 not ready yet?

Anyway: t is only a clean testing machine… but reinstalling takes time.

Has anyone else experienced this issue? Any advice, fixes, or workarounds would be greatly appreciated.
