Are you using HDMI? How is the quality of your cable? It sounds very much like a cable quality issue.

one sec I will try another cable

In my experience, HDMI just doesn't work well with macOS. Sometimes lowering resolution and/or refresh rate can help as can higher quality cables, but it's still not very good. Oddly, the same cable can run great when booted in to Windows.

DisplayPort works best with macOS, but you still need a good quality cable.

I am about to start installation of Mac using your guide, but I did have a question. I noticed that F_USB1 is enabled in your EFI. I have a Fenvi T919 installed with internal USB routed to F_USB1.

I also have a GC-Titan Ridge TB3 Addon Card with internal USB router to F_USB2. Is the F_USB2 internal port disabled by default in your EFI files, and if so is it necessary to enable it to work with the TB3 Addon card? I am attempting to power an LG Ultrafine 5K and have access to the integrated USB-C hub, webcam, and speakers.

Please update your profile to include your CPU, motherboard, and GPU. I can't make out what hardware you are using...

If you are using the Gigabyte Z390 M Gaming, your Fenvi card should work with my EFI folder as-is.

Thunderbolt will also work but USB2 will not work on the Thunderbolt card. I don't know why anyone would want to connect a USB2 device to the Thunderbolt ports so I made the decision to keep those disabled in favor of having all the motherboard USB ports working 100%. This due to the 15 port limitation of macOS. This doesn't affect Thunderbolt devices.

Thanks for the clarification, working on unlocking MSR now. Looking forward to getting everything up and running.

Hello all,
I've just finished my first hack-build! It was not easy (some noob problems mostly), but I made it: mostly thanks to @pastrychef EFI and config.

Unfortunately I have USB3 storage issue - it seems, that no USB3 device is detected by MacOS.

My hardware: Gigabyte Z390 M Gaming, i5-9600K, hyper-x 2*16 Gb 2400, Samsung 970 Evo Plus, Broadcom BCM94360CS2 wifi + BT card.
Besides USB3 all is working great.

I used EFI and config from #4 post (this thread), after install I did change system definition to iMac 19.1 (and generated new serial no.)

All settings in bios and bios version itself - same as pastrychef's instructions.

Weirdly I am sure that USB3 disks worked after installation, and just stopped after some reboot.

Any help?

Please post your EFI and I will help you fix your USB.

Edit:
Just download the attached file, unZip it, and install to /EFI/CLOVER/kexts/Other/. Also, delete USBInjectAll.kext.

Hi @pastrychef, awesome guide! Thank you!

I have a machine with the same mobo. It was updated to Catalina by "accident". It was working flawlessly before now i can only boot in safe mode.

Now I get some kind of panic error (screen grab attached)

I updated Clover.
Updated BIOS to F9g.
Did the MSR unlock thing.

OsxAptioFix2Drv-free2000.efi is the only one I go further until the panic, all the others i get driver error/couldn't allocate runtime error at the beginning

I tried your EFI no luck, couldn't allocate run time error.

Any suggestions?
Thank you
