I can't add myself/administrator with "Read&Write" privilege on my Macintosh HD Info tab. When I try to to add myself in the unlocked Get Info it says in a popup that I don't have the necessary permissions. My Mac min OS12.7.6

The "Macintosh HD" volume is complex with part of it being on a read-only signed & sealed volume. No one can modify its permissions....besides it would not matter even if you could as macOS would still not recognize it.

You can only modify items located within the "/Users" folder or on your external drives. Even within your home user folder, there may be items which you cannot modify due to deeper privacy & security features within macOS. Basically if you did not create or move a file/folder yourself, then you may not have any permissions to modify it or its permissions.
You must be logged in using an admin account first to make those changes
