I've got permissions problems with files on my MacOS 10.13.4 desktop.
When I try to correct the problems by hand, I see a curious issue:
Matt$ sudo chown Matt:Engineers TestFile
chown: TestFile: Operation not permitted
Matt$ ls -l
-rwx------ 1 _unknown _unknown 24281 Jul 19 2016 TestFile
This file was copied as part of a large data transfer from another system with different users. However, chmod should still honor root authority, and even with an unknown user ID, should still allow root or a sudoer to change it.
Any ideas on this situation?
How can assert authority over this file, and correct its ownership and permissions?

I have found that 'chmod' is broken on 10.13.4, but 'cp', 'rm' and 'mv' are not.
That is, as a sudoer I can:
It's a bit clumsy, but I can use a simple BASH script to fix one of these files, when I find it.
