disable tls 1.1

We have a client trying to meet new HIPAA compliance requirements, one of which is to use only TLS 1.2 . He has Safari 12.1.2 , which I understand has both TLS 1.1 and TLS 1.2 enabled. How can we disable TLS 1.1, and force him to use 1.2 only?

Apple and other browser vendors will remove TLS 1.0 and 1.1 in early 2020. Since the keyword here is remove, you may not be able to disable TLS 1.0 and 1.1 in Safari until Apple releases that more secure version next year..


The following .plist does not exist on Mojave 10.14.6.


Safari 12.1.2 uses TLS 1.2 by default and you can verify the TLS version in use at Qualys SSL Labs.
