NootedRed

iGPU compatibility

The entire Vega Raven ASIC family (Ryzen 1xxx (Athlon Silver/Gold) to 5xxx, and 7x30 series).

macOS compatibility

NootedRed is compatible with macOS 10.15 up to macOS 14.

It’s not possible to go below macOS 10.15 as the iGPU logic and rDNA code (used for DCN and VCN) were introduced in that version.

Prerequisites

• An OpenCore EFI configured according to our guide.
• Your system must not have a GCN 5 or rDNA AMD dGPU.
  • They can be disabled using the -wegnoegpu boot arg or the disable-gpu device property.
• Increase VRAM size.
  • 512MiB minimum, 1GiB+ for proper functionality.
• Remove WhateverGreen.kext or NootRX.kext.
  • This kext conflicts with them.
• Use MacBookPro16,3, iMac20,1 or iMacPro1,1 SMBIOS.
  • MacPro7,1 might result in a black screen.
• Do your macOS updates (the minor ones, not necessary to go from e.g. macOS 11 to macOS 12).

Backlight functionality

Usually only works on laptops.

• SSDT-PNLF.aml
• SSDT-ALS0.aml if you have no Ambient Light Sensor
• SMCLightSensor.kext
• BrightnessKeys.kext for keyboard brightness control (some vendors might require custom SMC kexts)

Frequently asked questions

Danger

This list is not exhaustive, for more information you should check the issues, potentially also the discussions.

What happened to the commit history? Weren’t there like a thousand commits before, spanning across several years?

A “controversy” with two ex-team-members. They didn’t contribute much to the project and it was deemed that they should not gain publicity from it.

I get stuck on a black screen or restart after black screen on Catalina

Update the kext. If still getting a black screen right before the Setup Assistant, force restart and it should fix itself.

My brightness control is not working properly

On Raven-based chips (1xxx-3xxx series) a bug was introduced after new backlight logic, it has no fix for now. Just be patient, this is a hobby project.

My external display’s audio appears, but no audio comes out of it

Known issue. We don’t know the problem yet; it works on most systems. You’ll have to be patient for now (again).

My HDR-enabled display boots to a black screen with flashing backlight

Disable HDR either from the BIOS, a tool like Smokeless-UMAF or by connecting to the computer remotely and doing it from macOS’ settings.

My OLED display cannot have its brightness adjusted

Update the kext, some code has been added to support this. If still not working, please contact us on Telegram.

I cannot adjust my brightness on Catalina

Update the kext; brightness control logic was added for Catalina.

Chrome, Chromium-based browsers and apps like Sublime Text cause graphical artefacts amongst other problems

Known issue, unknown cause.

For the browsers you can disable GPU Rasterisation inside chrome://flags as a workaround or just use Safari.

Anything else will likely require disabling GPU/Hardware acceleration.

If you can’t even open the (chromium-based) browser because of the issue, you can launch it like in the following terminal command

open -a Google\ Chrome --args --disable-gpu

Constant freezes and crashes on Sonoma

Cause of the compute dysfunctionality remains unknown. Latest commit should have minimal issues, as long as you have a static image as your background and no Memoji as the account avatar.
