This came up on the list a few months ago. See thread with subject "dying on osx” on 11 August and 4 September 2018.

The only way I managed to get it to work was by changing default_login_user and default_internal_user to my username.

As you say, wasn’t an issue with earlier versions of macOS X.

Any solution would be most appreciated.

James.
