Yes, I'm running the latest 2.0 beta.

So I digged a bit into this, and it seems that only the higher level abstraction as NSURLSession, which is essentially a shortcut for the Foundation URL Loading System [0], has TLS1.3 support. The lower layers, such as NSStream, CFHTTPStream and CFSocketStream don't support TLS 1.3. I don't know the mailmate sources, but maybe this information helps you a bit. > Ideally, MailMate should switch to Apple's Network framework, but that > requires macOS 10.14+ (MailMate is still 10.12+).
