Can't update or install plugins locally, macOS
error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version


Your local OpenSSL setup is trying to connect with an older, insecure TLS 1.0 protocol, which Github (and a lot of other sites) no longer support.

If you update it to use TLS 1.2, the error will go away.

If you're on something like MAMP/WAMP, etc. then updating to the latest version of their software is usually enough to resolve this issue.
