The file AliasPrefs.scm can be in 2 places. If you have ever successfully run AliasDesign (or AliasAutoStudio or AliasSurface) the file used will be here...
~/Library/Preferences/Autodesk/Alias/UserPrefs2018/AliasPrefs.scm
If you have not successfully run the file in the distribution area will be used...
/Applications/Autodesk/AliasDesign2018/AliasDesign.app/Contents/Resources/Comlib/AliasPrefs.scm
The name of the directorys change depending on what product you are running.
The change I made is to a single variable in that readable ascii file.
(ui-interface-symbol "learning_movies_dont_show_option" 0)
to
(ui-interface-symbol "learning_movies_dont_show_option" 1)
This change will prevent the "Essential Skills" Window from opening. When I do that I can run Alias on a machine with NVidia graphics on High Sierra.
It's possible that your cut is not running for some other reason, but If I was you I would look at files in both location to see if the value is set to 1.
