Hi, I'm trying to figure out how to edit the bootps.plist which is in the system / library directory. I have an M4 MacBook running OS 15.3.2 and I've held down the power button to go into recovery mode, and in terminal entered the 'csrutil disable' command and have restarted but when I go back to 'get info - Sharing & Permissions' I can't change any of the permissions. I need to be able to edit this file to create DHCP server.
How can I change edit permissions on the bootps.plist?
