Dosdude1 Catalina Patcher with upgraded iMac - no microphone, Metal issues

Hi everyone, I have a mid-2010 27" iMac with an upgraded Core i7 and a Nvidia GTX 770M with the boot screen ROM patch. It's a great machine and I have now attempted to install Catalina with the Dosdude1 patcher on a separate drive to test before overwriting High Sierra. I have two issues:

1. The microphone has stopped working, both for High Sierra and Catalina. Could the patcher have somehow affected this? Would it be an EFI issue? I disassembled the machine and checked the wire between the microphone and the logic board and it appears fine.

2. I can't seem to install the patcher without the "legacy video support" patch being applied. This results in very poor video performance on the Metal-capable GTX 770 board, pretty much the same as the old ATI card. How can I disable this patch or choose to not install it?

(I posted this separately because it seemed a bit rude to add to a 350 page thread but if this isn't polite, I can repost there)

Thank you!

Two things:

1. I reinstalled macOS and then applied the patches afterwards with no legacy video. This fixed the Metal issues - thank you. However now I have no wifi. Any tips on re-enabling it?

2. Microphone audio is still not working. I think there must be some kind of hardware issue so I ordered a replacement microphone and cable.

Try to repatch wifi. Sometimes it doesn't "stick" at first attempt.
Did you try to reset PRAM to try to fix your microphone? Sometimes it works for that kind of problems

I have re-patched multiple times and even reinstalled macOS again and re-patched and I can't get the wifi to work. It's definitely working - I'm using it right now in High Sierra - but for some reason this patcher isn't working.

The weird thing is that if I ran the patcher automatically including the legacy video support, it worked - but of course then Metal didn't. So, going back to my original question, would it be possible to /remove/ the legacy video patch?

And the PRAM had no effect on the microphone. Must have failed, weird.

Consider buying one of these with adapter for miniPCI.
That's the one I have in my iMac 2007 and I have continuity working.

I bought it in ebay for about $40,00 US

Guys, I have a 3,1 running Yosemite right now and I want to try the Catalina patcher, never did it before.

I have a few video cards at hand and I was wondering if I can install Catalina with any of them without needing to flash them.

This is what I have:

2 Mac cards
AMD 5780 - as I understand this one does not work at all.
GEFORCE 8800GT

2 PC Cards - Both support Metal 2 but they are both unflashed.
- EVGA NVIDIA GTX680 4Gb Classified
- NVIDIA GeForce GT 630 2GB


Tnx!

I know in the initial Sierra Patcher by Dosdude that certain Wi-fi modules were not supported. It really depended upon which wi-fi module Apple placed in the Mac at the time. It can be found in the known issues. This may have continued to carry over in the following patches.

The Isight camera/mic, i think, was also an issue as well. It's noted here in his patcher for Mojave, so I'm guessing that it continues to be a hit or miss problem. Probably based on model of camera that was installed.

I believe if you install Catalina - that it has the NVidia drivers installed. As long as it supports Metal you should be fine. The only way to know if the card works would be to install it and try. Either you won't get a picture or you will. I think the only missing thing would be the boot loading screen that you won't see as i recall.

I myself got a flashed RX 580 for my Mac Pro 4,1(5,1 now due to upgraded processor)

Here's Apples Official list of supported cards.

TonyMac which does hackintosh's(Gulp!) has a bigger list of cards that have been used with Mojave( and i'd assume also work with Catalina as well here).
