MacBook Pro 4,1 freezing during MacOS setup after using dosdude1's patcher.

EDIT: I find it impossible that that's how I managed to get High Sierra installed but here goes. I "just" had to set my 17-inch MacBook Pro in target disk mode then perform the installation and initial setup through a different machine. I seriously can't believe that this worked - but I guess I've got to, since I'm seeing it!

It's not freezing exactly. The keyboard, trackpad and any connected input devices just... don't register (and no caps lock light) while only the power button works - which is weird since the power button is connected to the keyboard itself. I've tried Sierra, High Sierra and Mojave through dosdude1's patcher but while it appears they install fine and the post-install stuff goes on smoothly, the same issue happens on all three of them. And it happens only during the initial setup - it works just fine in the pre-install environment or other operating systems or during the boot picker.

The only natively supported OS I tried is El Capitan - which of course causes me problems because it just doesn't want to realise that it's a legit copy downloaded from Apple's servers... and Leopard, which is entirely too old for anything.

Why didn't El Capitan work? Did you try setting the time back pre-install?

You've likely run afoul of an issue with the signing certificate used by the OS X 10.11 installer being too old. Luckily, there's a simple fix to get around it: https://apple.stackexchange.com/que...er-loop-no-packages-were-eligible-for-install

Edit: This is what @theMarble referred too when they talked about setting the time back pre-install.

Didn't work. I'm still getting the same message. It reads, word for word "This copy of the Install OS X El Capitan application can't be verified. It may have been corrupted or tampered with during downloading."

Still, I don't care about El Cap. I was thinking I'd install it and then upgrade to either Sierra or High Sierra in case that would fix the unresponsive inputs problem.

It sounds like the post-install tweaks weren't applied (correctly). Have you tried re-applying and making sure to select the correct model?

I just select my model (MacBookPro4,1) and barely touch anything. The only post install thing I change is that I add support for the external superdrive because the built-in one doesn't work. I really doubt that messes with it.
