The problem isn't Python, it's OpenSSL. OpenSSL got TLSv1.2 support in version 1.0.1. Any older version of OpenSSL doesn't support TLSv1.2. That affects a number of platforms: - the system Python on macOS, which link against the system OpenSSL (an anaemic 0.9.8zh) - most of the older (pre-3.6) python.org releases on macOS, which have the same problem - any Python on a Linux operating system with an older OpenSSL So the backport needed is to backport a newer OpenSSL to the platform.
