"Modifying requires an administrator name and password"
I have a Mac Mini, running High Sierra 10.13.6. Virtually anything I want to drag from the desktop to the hard drive (mine is called "Raccoon"), I have to authenticate and put in the password. This drives me nuts and takes time. I'm the only person in the world who uses this computer. How do I turn this annoying thing off? I got rid of the password to log in to the computer upon startup, but it did not solve this password requirement problem.
Thanks for any help.
