Caution 10.11.2

Permissions are not dealt with in the background; they are no longer available to the user to 'fix'.

Do you mean that a user on a multi-user system cannot run repair permission in disk doctor -- or cant change permissions on a file or folder?

I think apple is spending a little too much time on the exterior design & 0 or not enough time on the underpinnings.

Just discovered a problem with Snow Leopard and read only not repaired in any update - in regard to the concept if I am the owner - I am the security officer and should be able to move a read only set of folders and items anywhere I want without them going missing.

Permissions are not dealt with in the background;

Actually, they are - at least according to Apple:

https://support.apple.com/en-us/HT201560

they are no longer available to the user to 'fix'.

I am aware of that and, according to Apple, no longer necessary to 'fix'.

Then the problem has to be something to do with your user account.
