Defective gradients in macOS Catalina 10.15.0 (19A583)

[Rodolfo2909]

Hi, I need help with the gradients. I have another volume with Mojave 10.14.6 and the graphics are perfect, they don't show any errors. However, Catalina has that defect, even though it is a clean installation. My graphics card is an RX 470 4gb. I have nothing loaded in my config.plist since this card works natively in Mojave. I appreciate helping me solve this.

I have the same problem with Rx 570 4gb here.

See if this works:

1. Turn off SIP.
2. Open Hackintool.
3. Switch to the Tools tab and press "Disable Gatekeeper" to mount the disk in read/write mode.
4. Switch to the Display tab and just export without changing anything. Hackintool creates three files and one folder on the desktop.
5. Drag and drop the folder "DisplayVendorID-xxxx" to /System/Library/Displays/Contents/Resources/Overrides
6. Restart, and remember to turn SIP back on.

Thanks for your detailed reply. Now my display effect has been improved.
I tried putting "xxx. kext" in the "L/E" folder before, but it lost the audio output and didn't always work

I also posted the similar method a half of year ago.

<< Solved >> - Forcing RGB mode for problematic displays

Is that related to the driver of RX 580? Those don’t happen at all on Windows. Yes, it tells macOS which driver to use.

Yes I think this is your method originally. You have my thanks!

I didn't remember where I had learnt this. Fixed the banding issues with my 10bit colour compatible display.

It should be an issue caused by macOS itself as some Mac users also reported the same. I did some trial and error with their unclear and complicated clues.
