Some courses in Academy are using Esri Geodatabase (File Geodb Open API) Reader/Writer (FILEGDB).
I don't think FILEGDB is supported by FME Form for macOS, I would recommend you to use OGC GeoPackage instead of FILEGDB.
I hope Safe will check if users can learn all FME Academy coureces regardless of their OS and revise them if necessary.
"The Esri Geodatabase (File Geodb Open API) reader/writer provides Geodatabase support without an installed Esri product on Windows and Linux;"
