How to Enable AMD RX 6700, RX 6700 XT, RX 6750, RX 6400 and RX 6500XT ​

This guide describes how to enable AMD RX 6700, RX 6700 XT, RX 6750, RX 6400, and RX 6500 XT on macOS and is applicable to both, i.e. Clover and OpenCore. By following this guide, you'll be able to achieve full QE/CI on your AMD Navi 21, 22, 23, and 24 series GPU.

Overview​

Apple has been using a wide range of AMD GPUs in their Macs for a long time. With the release of macOS Big Sur (11.4), includes the drivers for AMD Navi RDNA 2 architecture lineups, which include AMD RX 6800, RX 6800XT, and 6900XT GPU variants. This means from macOS Big Sur 11.4 and future macOS versions, we can have the GPU working, as long as macOS supports it. Later with macOS Monterey (12.1), support for AMD RX 6600 and RX 6600 XT was also supported.

As always, Apple has been picky in terms of hardware support. It can support hardware in a limited way, even from the same family. With the release of AMD Navi, Apple started to support these GPUs, but not all the models were supported in the lineup. This means the rest of the GPUs were simply not supported on the macOS side. Over the period of time, we thought Apple might introduce the support in a latter version of macOS but Sonoma is already released and still no support added rendering the other cards useless on macOS. There are also a few models such as RX 6950XT, and 6650XT which do not work OOTB but can spoofed to a closer model and made to work. However, cards such as RX 6700, RX 6700 XT, RX 6750 XT, RX 6500 XT, and RX 6400 are simply not supported. See Spoofing GPU for more information.

It has not been so long when NootedRed came into the highlight and it is still one of the major developments in this community. Since then, it has been really possible now to use the AMD APUs. We also have a dedicated thread for the AMD APUs. With the efforts of developers in the community and with the recent development, there is a new driver NootedRX and it is now possible to use the Navi21 and later series on macOS, and that too with full Graphics Acceleration.

Please note that this is an early stage of development for AMD Navi 21 series unsupported GPUs on macOS and as of now, this could be a limited experience. Certain features may not be available, bugs are expected and there can be issues across different systems, but an official version has to be released yet.

Requirements​

---

Following are the requirements for enabling AMD APU on macOS. Please ensure you meet the requirements before proceeding with this guide.

Motherboard	macOS Compatible UEFI Motherboard.
CPU	macOS Compatible Intel/AMD CPU. See CPU Compatibility for more information.
GPU	AMD Navi 21, Navi 22, Navi 23 and Navi 24. See AMD GPU Compatibility for more information.
Boot Mode	UEFI. Legacy Boot Mode isn't supported yet. CSM must remain disabled.
macOS	Pre-installed macOS Big Sur 11.x or Later
SMBIOS	The SMBIOS requirement remains the same as usual.
Monitor	Any monitor/TV with DP/HDMI/DVI display connection. DVI users can use DVI to HDMI adapter/cable. DP users can use DP to HDMI adapter/cable.
Bootloader	Clover OpenCore
Kexts	Vanilla Graphics Kexts in S/L/E Lilu 1.6.4 or newer NootRx

Compatibility​

For more information on APU compatibility, refer to the thread linked below.

AMD APU Compatibility List for macOS

AMD APU Compatibility List for macOS Limitations Only supports Metal 2 and Metal 3 compatible APUs. Supports macOS Big Sur 11.x to macOS Sonoma. Only supports UEFI Motherboards. DP/HDMI Audio isn't supported at the moment. VGA isn't supported at the moment. Sleep/Wake is broken at the moment...

STEP 1: Setup BIOS​

The very first step is to set up BIOS to have the AMD APU Enabled on your System. If you have followed the BIOS Setup Guide, you will not require this step. However, If you haven't, follow the steps below to set up your BIOS for AMD Graphics Card.

1. On your target computer, boot to BIOS. Refer to your user manual for the BIOS Key
2. Set the following parameters as shown.

Settings	Value	Notes
Initial PCIe Output Display	PCIe/Auto/Enabled	Depending on your System's BIOS, use one of the Values available
Intel Processor Graphics	Disabled	This is usually found under Advanced>PCI Configuration.
Resizable BAR/Clever Memory Access (C.A.M)	Disabled	This is usually found under Advanced>PCI Configuration.
Integrated Graphics Controller	Disabled	Found on AMD Systems This is usually found under Advanced>AMD CBS>NBIO Common Options>GFX Configuration.
CSM (Compatibility Support Module)	Disabled	This is usually found under Boot

3. Save & Exit Setup

NOTES:

• If your Laptop has AMD dGPU, it is recommended to set the Graphics Mode to Switchable Graphics.
• If your system does not have any of the settings as mentioned above, you can simply skip those settings.
• The above settings are for Graphics only. See BIOS Settings for more information.
• If there is no option to disable IGPU and IGPU loads under macOS, disable it using -wegnoigpu boot arg.
• If your system does not have any of the above settings in BIOS, ignore such settings.

​

STEP 2: Add Required Kexts​

The next step is to add the required kexts to enable AMD Graphics. NootRX doesn't work standalone. Lilu and NootRX are needed together to work in conjunction. To install the kexts, follow the steps below.

1. Download NootRX.
2. Mount your ESP.
3. Depending on your bootloader,

For Clover:
1. Copy NootRX.kext to the EFI/Clover/Kext/Others directory.

For OpenCore:
1. Copy NootRX.kextto the EFI/OC/Kexts directory.
2. Open your config.plist and add NootRX.kext entry in the Kernel>Add section of your config.plist.

NOTES:
Your kext list and entries may differ as each system is different and will have different requirements.
Do not use WhateverGreen or NootedRed with NootRX.kext.

4. Save config.plist

STEP 4: Boot using the new Configuration​

Once you're done with the above steps, you'll need to boot with the updated configuration. Simply restart your system. It is recommended to reset NVRAM twice at least. After performing all the above steps, restart your system for the applied changes to take effect. It is recommended to reset NVRAM twice at least.

Verifying Graphics Acceleration​

---

The next step is to verify whether the graphics acceleration is working or not. Follow the steps below to verify the Graphics acceleration.

Low Geekbench Scores​

If you're using an AMD system and getting low Geekbench scores, all you have to do is disable the default Algrey patch and enable the Shanee patch (Fix PAT).

Greetings, thank you for always trying to guarantee the proper functioning of the hackitohc, I have Sonoma 14.1.1 with Intel 8av generation coffee lake processor, Intel H310 board, 16GB Ram, and RX 6500 XT 4GB video card, install the Kexts NootRX v1.0 , but starting the startup loading bar restarts the computer.
boot args keepsyms=1debug=0x100 alcid=1
WhateverGreen removed the installation as you recommend, the bios configuration as indicated in the guide, which could be causing the failure, thanks in advance for the help. Greetings.

No idea without the PR Files. Attach your EFI you're using to boot.

Are you using the same hardware as indicated in your profile or is it a different one?

Are you using the same hardware as indicated in your profile or is it a different one?

Greetings, I could not connect before, problems with my internet, I am using another profile that I described in the initial question, this hardware: Intel Coffee Lake generation 8av, Gigabyte H310 board, 16GB of Ram and 4GB RX 6500 XT video card thanks for everything

Navi 24 Graphics are not supported yet. Why you say RX 6500 XT works?

The support is coming soon. Another dedicated thread for a single GPU would not make sense.

OK thanks
