It’s not about the folder it’s what’s inside the folder. I need to edit some plist file but i am getting this same error.

As I stated, you cannot modify that folder which includes everything in it.

The System Volume is mounted read-only. It has nothing to do with SIP or any variation of “rootless.”

What do you wish to change? Not the specific plists, but the end state you hope to accomplish by changing those plists.

Yes, that is correct, you cannot modify that folder. Why do you think you need to?

There are elements of the Operating System where you can.

But as previous posting above mentions this is Off Limits to affecting changes.

The Only area open is in the User Account Folder ( Home Folder )

Simply put - No
