Hi @PBJE,
Welcome to the Autodesk Community .
As @maxim_k mentioned earlier, you can try to export them manually from the locations.
~/Library/Application Support/Autodesk/AutoCAD 2019/R23.0/local
~/Library/Application Support/Autodesk/AutoCAD 2019/R23.0/roaming
After moving your own settings to the new machine in the same location, you will be able to migrate them automatically when you first open a new version of AutoCAD on that same machine.
Please note that for versions 2017 and older, there is no automated migration of custom settings between versions, as there is with the Windows releases. Settings are migrated from an AutoCAD for Mac 2017 or later release only. See About Migrating Custom Files and Settings.
Please let us know, if you need a hand by replying to this post or to my email from case 15247448. I am happy to help.
Regards,
