Other MacOS SSL Issues

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。

We had two types of errors reported recently:

This issue is not yet resolved

One issue was getting "[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1108)>" on startup (just after checking aria2c and 7z)

This issue is not yet resolved

"urlopen error [SSL: TLSV1_ALERT_PROTOCOL_VERSION] tlsv1 alert protocol version (_ssl.c:590)"

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