Which discrete AMD Graphics card are going to be using? I ask because the AMD Integrated GPU in your CPU isn’t supported in macOS.
Here is a link to see which old AMD dGPU’s are compatible with macOS.
No point anyone providing an EFI if you don’t have a compatible GPU.
Other points:
The Mediatek MT7922 (RZ-608) WiFi/BT card isn’t supported in macOS. There was some hope that it would be with the release of Tahoe 26.3 or 26.4 that coincided with the release of the MacBook Neo. However, Apple used a different Mediatek card (MT7932) that uses a different transfer protocol, which isn’t available as an upgrade card.
Your 2 x Samsung NVME drives aren’t the best option for use as a macOS boot drive. I assume you have Windows or Linux, or both already installed on these drives.
Western Digital/SanDisk NVME drives from the SN770 or SN850 series are usually the best options for use as the macOS boot drive. These WD drives use an NVME controller that is fully compatible with macOS and work really well as the boot drive.
Which drive do you plan to use for macOS?
You would be best served looking to install macOS Sequoia in the first instance, as Tahoe throws up a few compatibility issues that need a little bit of experience to get around. Realtek Audio not working natively is one of the main issues, plus a number of common Kexts causing kernel panics during the installation process is another.
Let us know what you plan to do regarding the discrete GPU and we can see what we can provide in the way of help or even a working EFI folder.
First of all, thank you for your quick response.
They mentioned that NVIDIA is not supported. I have a spare Sapphire RX570 2GB at home, and it seems to be compatible according to the list.
1- I can connect via Ethernet, or I can try using a Fenvi Wi-Fi card.
2-3-4- I have Windows 11 installed on a Samsung 9100 Pro. I can use one of the others, depending on which one is compatible.
5- Sound is not very important. I’ll be using it experimentally, mainly to transfer my archives from iPhone to iCloud Drive via macOS Photos.
Check the Device ID for your Sapphire RX 570 2GB dGPU. Just to make sure it is compatible.
Given you plan to use an older dGPU you might be best served installing Ventura in the first instance, as it caused less issues than the newer macOS releases with older Polaris dGPU's and Broadcom WiFi/BT cards. You can do all you outlined above in Ventura and the Fenvi card (T919) will work out of the box in this older macOS release.
You will need to disable the AMD IGPU/APU in macOS.
This can be done in the Bios or with a custom SSDT or with a boot argument. The Bios option is the safest and can always be looked at again once macOS has been installed.
For your own benefit I would recommend that you remove all drives from the system when installing macOS, except the drive you plan to install Ventura on. This drive along with the USB installer should be the only drive connected in the system.
