How disabling TLS 1.0 on Warwick web applications affects Mac users

From 23 May 2017 onwards, we will disable the TLS 1.0 encryption protocol across the University's web services. Disabling TLS 1.0 prevents it from being used to access Warwick websites via an insecure web browser or application. We're making this change to keep the University's websites safe and secure.

However, this means you won't be able to access parts of the website using the Safari web browser, and older versions of Google Chrome or Mozilla Firefox, on Mac OS X 10.10 (Yosemite) or older.

We recommend you upgrade to the latest version of macOS (10.12 Sierra).

If this is not possible – e.g. because your Mac model or OS X version do not meet Apple's system requirements – then we recommend either of the following actions:
