 	ctype = g_content_type_guess(path, NULL, 0, NULL);
 	icon = g_content_type_get_icon(ctype);
 	g_free(ctype);
 
 	if (icon != NULL)
 	{
-		gtk_icon_size_lookup(GTK_ICON_SIZE_MENU, &width, NULL);
-		info = gtk_icon_theme_lookup_by_gicon(gtk_icon_theme_get_default(), icon, width, GTK_ICON_LOOKUP_USE_BUILTIN);
-		g_object_unref(icon);
+		info = gtk_icon_theme_lookup_by_gicon(gtk_icon_theme_get_default(), icon, 16, 0);

Notice that the constant GTK_ICON_LOOKUP_USE_BUILTIN  was used for the last parameter which is flags - I believe this is why the icons looked differently on macOS so I used 0.

The width was determined by https://developer.gnome.org/gtk3/stable/gtk3-Themeable-Stock-Images.html#gtk-icon-size-lookup but based on the documentation this function shouldn't be needed and GTK_ICON_SIZE_MENU is 16px. I use the same in ProjectOrganizer and it seems to work fine.
