I am primarily a Linux guy, but I wanted to see how well this hardware would run OSX

The only thing that tripped me up was needing to add agdpmod=pikera. Without that the screen would go black.
Boot Args: -v keepsyms=1 alcid=11 agdpmod=pikera

I got a memory warning on startup:

I believe this is because it is expecting ECC ram in a MacPro7,1. But it seems harmless. All the ram is visible.

You can hide the memory warning with this kext, https://github.com/IOIIIO/MacProMemoryN ... r/releases

It gets everything except my Gen4 PCIe NVME drive correct. That's a 1TB Sabrent Rocket 4.0 which is my Linux boot drive (Linux is my day-to-day OS on this box).

The other drives listed as external are actually external.

I poked at it a little bit, but since I don't even mount it under OSX I didn't dig too deep. In your case, make sure you have ExternalDiskIcons set to true in your config.plist. I think there is a way to fix it in the DeviceProperties section of config.plist. My diskutil list looks like this (note the Russian disk label on disk7s1 caused by my usb stick installer for some reason deciding I wanted to do the whole install in Russian):

Hi Rasmus,

I have the same setup as you and have managed to install Catalina. However everything work apart from my USB seems to disconnect from time to time, only really noticed it while backing up to an external usb 3.0 hard drive. Any chance I could get a copy of your EFI folder or .plist? I am using OC 0.5.2, every time I try to upgrade to 0.5.4 it kernal panics, don't understand why.

Thanks for any help.

Hi Rasmus,
Is it possible you can take a look at my efi, I am struggling from past 3 days. Mojave boots and installs smoothly but I am not able to install Catalina, I have even contacted couple of people on discord as well. Here is my efi that boots perfectly for Mojave.
Whats happening with me is, as I click on Install button on recovery Installer it takes me back to Original MacOS utility window. This loops continuously. Please take a look https://drive.google.com/open?id=1NjeCH ... FRLNX1jfar

@rasmas,

I used the technique described in this reddit post to solve the external icon issue and can confirm it works.

@ramsus et al,

I'd be interested in the BIOS settings people have used successfully. I cannot get my hack to post when making changes to my BIOS settings. I think it has something to do with the XMP Profile but I need to do further testing. Any insight would be appreciated.
