Hi,
thank you for your screenshots.
Sorry to say that AutoCAD on Mac does not have the export and import function for IGS.
If it's a one time case upload the DWG-file here and I'll convert it to IGS, if you need that more often you might think about a Windows version of AutoCAD on bootcamp or VmWare or anything similar.
