**edit: trialing a workaround using CURL instead of python's URLOpen, lets see how that goes...**

エラーは、urlopen が呼び出されたときに install_data/common.py の 813 行目、__getFilenameFromURL で発生します。この issue は、Python の URLOpen の代わりに CURL を使用する回避策について言及しています。macOS 上の Python 2.7 環境における SSL/TLS 構成、特に OpenSSL バージョンの互換性を調べることから始めてください。CURL の回避策が実装されているか確認し、URL 取得ロジックをテストしてください。「Done」とは、インストーラーが影響を受ける macOS システム上で、SSL エラーなしにリストされた URL を正常にクエリすることを意味します。
