UGS Whats the Status

Does anyone know the status of UGS working OK on a MacOS 10.15 Catalina.
I Get terminating with uncaught exception of type NSException. when I run it.

Also on a Windows machine running UGS if I try to run the probe module in inch mode
It does not work right. When you check zero, after you run, it goes off in the wrong direction anyone using
UGS probe in inch. mode?

And one more I do not see anyone working the source code project for UGS Its been on the
2.0 rev for more then a year now… I think we need a open source project that is moving forward.
CNCjs also not moving forward and the keybinding is not good. UGS has all the right stuff be
no one looks to be working on this?
