Try re-enabling SIP.

Then put your overrides in /Library/Displays/Contents/Resources/Overrides/.

SIP re-enabled. I get the grayed out ghostbuster logo when I drop files on it. Tried to change permission and that comes up with "don't have permissions". Also tried booting up with Catalina but that says my new drive with Big Sur is incompatible. Will install Big Sur on 2nd drive, boot off that one and see if I can edit first one......

It's telling you that you don't have permission to access the /Library/ folder????

I just tried dragging-n-dropping an empty folder to /Library/Displays/Contents/Resources/Overrides/ and didn't have any problems.

Affirmative. No access. I can’t even add myself as a user with access.

I don't know why you can't access the /Library/ folder.

Just don't mess with the /System/ folder. That's off limits now.

/Library/ folder should not be off limits. If you can't write to it, macOS will probably give you all sorts of problems.

/System/ folder is different.

  • Reboot into recovery mode (⌘-R at boot).
  • Mount your main disk (enter Disk Utility, select the gray Macintosh HD, click Mount, provide your password, close Disk Utility).
  • Open up a terminal (Utilities -> Terminal), backup the overrides directory, copy in your new override file, and reboot:
    • cd /Volumes/Macintosh\ HD/System/Library/Displays/Contents/Resources
    • cp -R Overrides Overrides.bak cp -R /Volumes/Macintosh\ HD/Users/jrr/Desktop/DisplayVendorID-10ac Overrides/
    • reboot
