Running on a current gen iMac(latest release). Trying to set up a shared drive over my network(external USB drive). When I try adding the whole drive, it gives Everyone Read access. The only change I can make is read/write. The write only and none are grayed out. My account can have any of the 4. That part works fine. It's the Everyone access that I can't adjust(nor delete). When I try just adding a specific folder, I set Everyone to None, and my login to read/write. I go to my other machine to test it, and I can log in and read/write under Guest. Any thoughts on how to make this actually restrict to what I set it to?
