We could not finish testing this tool: No direct macOS installer was found through the official English and Chinese download pages or their linked download script. The desktop buttons target Windows .exe files; the published Apple routes lead to the App Store, which this run explicitly excludes. KingDraw could not be installed or launched through a permitted route.
