Hi @Samu372, thanks for your question.
It seems that you don't have gams in your PATH, so the command igdx fails. Please use one of this path "/Library/Application Support/GAMS" or "/Users/username/Library/Application Support/GAMS" when you call the command igdx, or add the path in your PATH variable.
Unfortunately, I don't have much experience with the MacOS GAMS version. You might find more information at https://www.gams.com/latest/docs/UG_MAC_INSTALL.html
