VNCSERVER: Couldn't find "xauth" on your PATH

Attempting to run vncserver as non-root user gives me this error:

couldn't find "xauth" on your PATH

So I do a search for xauth:

find / -name xauth

which finds it in /usr/X11/bin

Also, knowing that when logged on as root I don't get this problem, I assume that root must have this in its path so I log on as root and run:

echo $PATH

This confirms that /usr/X11/bin is in the root users path.

I Log out of root session and add xauth to path:

PATH=$PATH:/usr/X11/bin && export PATH

vncserver now runs successfully but with some errors referring to permissions on the ~./vnc & ~./Xauthority folders.

For some reason root:root is owner of the .vnc in my root folder, presumably because I had run vncserver initially while su'ed from my non-root users session...

So:

pfexec -R marc:staff ~/.vnc

pfexec -R marc:staff ~/.Xauthority

Sorts that out!

vncserver -kill :1

vncserver

and all is working great!
