<< Solved >> 10.15.4 Update - how to disable HDR support?

[DsurioN]

I found out how to do it in Recovery Mode in Terminal.
command sample:

cd /Volumes/macOS/System/Library/Displays/Contents/Resources/Overrides
cp -rf /Volumes/macOS/Users/yourName/DisplayVendorID-1e6d .

This did the trick for me, thanks!

How can you copy to this folder ? I disabled SIP and still can not copy.
I'm using Hackintosh

Just use ‘sudo mount -uw /‘ and relaunch the Finder by holding Option key + Right Mouse Button of Finder icon -> Relaunch

Thanks, everybody.

I've been a Hackintosh man for years,
and
I solved my LG HDR issue on a REAL MacBook Pro using this technique.

Great community!

I solved the issue by patching EDID. There is a simple ruby script patch-edid.rb. Put it at any place, then run it from console ruby patch-edid.rb. It will create a folder DisplayVendorID-xxx, and a single file in it. This folder should be copied to this path /System/Library/Displays/Contents/Resources/Overrides. To do that you probably would need to disable SIP. Once it's done, turn off/on your monitor or restart a PC. After that it shows RGB to me. However HDR checkbox is now absent, but that's actually was a goal. I don't need an HDR for whole system, and even with disabling/enabling HDR previously by checkbox, it still not the same as SDR, cause Mac OS anyways sent an HDR signal to monitor.

Thank you soooooooo much, what a relief and what an easy fix to apply with these tip! Thanks!!
