I recently updated my MacBook Pro to BigSur. Although it is running fine, it is not recognising my external display properly (just like in any previous MacOS release). Long back I had got solution which is explained here. In order to do that, I need to override the display settings by copying a file to /System/Library/Displays/Contents/Resources/Overrides/

But my problem is I am unable to copy the file to the above directory as it is read-only.

The steps I followed,

  • I disabled the SIP by booting into recovery
  • I rebooted my MacBook Pro

And I am on my admin account.

When I was in my MacOS Catelina, I was able to copy that file to above location.

  • I ran across this online and found (a different) article about that. TD;LR SIP has changed and you need to do more https://eclecticlight.co/2020/06/25/big-surs-signed-system-volume-added-security-protection/ – Steve Chambers Nov 28 '20 at 23:45
  • Thanks Steve. I went through the article you have shared. To be frank, I do not know that much deep in MacOS operating system. What I understood is, it very hard to to make any changes to the system volume as now everything is SHA hashed! – Aravind D. Chakravarti Nov 29 '20 at 03:01
  • Hi again Steve, I solved my issue by copying it to /Library/... folder as explained in https://developer.apple.com/forums/thread/649832 – Aravind D. Chakravarti Nov 29 '20 at 03:59
