I recently bought a Radeon video card as my old Geforce is not supported since Mojave. I was then ready to switch from High Sierra to Catalina and had the objective to use a Fusion Drive in the process, as with HS my HD was mostly unused and my SSD nearly full.
Hardware
- Motherboard: Gigabyte AORUS - GA-Z270X-Gaming K5 (I updated it to the latest BIOS available, F9c)
- RAM: Corsair Vengeance LPX Black DDR4 2 x 8 Go 3000 MHz CAS 15
- CPU: Intel Core i5 7400
- SSD: Crucial MX300 M.2 2280 - 275 Gb
- HD: Seagate BarraCuda - 1 To - 64 Mo
- GPU: Gigabyte GV-RX580AORUS-8GD
- Headset: SteelSeries Arctis 7
For sound I don't use MB soundcard, for sound on my screen speakers I use sound from HDMI and my headset has a dedicated USB soundcard. So I deactivated sound in MB BIOS (but I think sound kext is VoodooHDA for this MB).
Steps
1 - Create a bootable USB installer for Catalina with Clover installed on it
See How to Create a macOS Catalina Public Beta Installation USB, for a starting point.
I had to:
- Add specific kexts for my hardware (ethernet atheros e2200).
- Replace ApfsDriverLoader.efi with apfs.efi from a working Catalina installation (my MBPro)
- Activate USB ports limit patches for XHCI
2 - Restart computer and boot from created USB key
After a bit of waiting you should see the following screen
Here I wanted to create a Fusion drive for Catalina installation, so I used TNCS-0045 - Do-It-Yourself APFS Fusion Drive guide, once the fusion drive is created you can go on with a normal Catalina installation on your diy Fusion drive.
Important: every time installation process needs to reboot you have to boot from USB install key and choose your fusion drive in Clover boot menu.
3 - Plug in your Time Machine drive when asked (optionnal)
4 - Copy EFI Folder on your SSD EFI partition
If you don't mind to use a USB key to boot up Catalina you're done .
Use Clover Configurator (or any other appropriate tool) to mount your SSD EFI partition et copy EFI folder on it.
