Catalina 10.15.2 Mini Guide
I took about a half hour to test out an install of Catalina on my 9020 MT system with RX 570. If you've followed this guide for Mojave your BIOS should already be set up properly for UEFI booting. You can leave Legacy Option ROMs enabled if you want to. It doesn't prevent AMD graphics cards from working the way it did in Mojave.
If you haven't flashed your BIOS yet, follow the instructions found in the first post under Step 2:
Step 2. Update your BIOS and Change the Settings
This is a "barebones" guide for those that need to have Catalina installed right now for whatever reason. Could be to use the latest Xcode, or the newest version of Final Cut Pro X. Have a look at the glorious sunny shores of Catalina island because that's what will soon be on your macOS Catalina desktop.
Note that this is for a clean install of Catalina only. Try out this install on a clean SSD or HDD.
The primary difference between this guide and the main Mojave guide is that you don't install any kexts to /L/E. They will all go into the Clover/kexts/other folder on the EFI partition instead. This guide also uses VirtualSMC.kext, not FakeSMC.
1. Make your USB installer using
Unibeast 10.0.0 from tonymacx86 downloads. Directions:

If you have never used Unibeast before you can watch the following video for a step by step guide.
Your Mac must have at least an Intel Core 2 Duo processor and be able to run older versions of Mac OS X and use Unibeast to create your installer. If you would like to buy, borrow or rent a used Mac mini to create your installer, the 2010 models are the best choice. They all have a Core 2 Duo...

2. Next, mount the EFI partition and replace the existing config.plist with the custom one from post #1 of this guide. You can simply delete the existing one then drag and drop the new one into the Clover folder. Download USBinjectall kext, HFS Plus.efi and AppleALC kext. These can be found attached at the end of post #1 as well.
3. Delete VboxHFS.efi from drivers/UEFI folder, add HFSPlus.efi in it's place. Delete the two non-Intel ethernet kexts from Clover/kexts/other and add the AppleALC kext and USBinjectAll kext to the kexts/other folder. Here's how the final kexts/other folder looks:
4. Download the custom SSDTs zip file from the end of post #1 and add all of those files to Clover/ACPI/patched folder.
Now you should be ready to boot UEFI from your USB installer and complete the Catalina install

Do not run any version of Multibeast (especially 11.3.0) during the post install phase. It's not needed and may cause problems.
1. After the install is complete, reboot and download the latest Clover Configurator app. Mount the EFI partition of your
USB drive and copy the whole EFI folder to the desktop. Now unmount that EFI and mount the hard drive's EFI partition with CC.
2. Copy and paste the EFI folder on your desktop to the EFI partition of your hard drive that is mounted.
3. Eject your Unibeast USB, pull it out of the USB port. Reboot and your should now be booting from your hard drive that has 10.15.2 installed to it.
4. Follow
Step #5 of the guide in post number one:
Step 5. Enable iMessage and Generate a Unique Serial Number
Everything went perfectly smooth for my install, no hiccups to report. Let me know how it works out for you.
