I have created a macro that changes the correction language of all the elements (text boxes, tables, groups...) in a PPT. I ended up with a code that works perfectly fine in Windows. However, when the macro runs in macOS it gives the error:
Compile error: Method or data member not found
and highlights ".LanguageID" in the line:
Slides(i).Shapes(j).TextFrame.TextRange.LanguageID = iLanguageSelected
