Known Issues with Unsupported macOS

Known issues related to running unsupported macOS versions on your computer:

Apple only supports the three most recent versions of its macOS operating system – this means many software developers will only release feature and security updates to devices that are running a supported version of macOS.

Running an unsupported version of macOS may limit access to features and collaboration tools in Microsoft Teams (such as breakout rooms) and Microsoft Office products.

The macOS operating system has root certificates built into it that allow your browser and other applications to validate the various websites and servers your computer connects to. This establishes a chain of trust that helps to prevent malicious actors from posing as legitimate websites.

Unsupported versions of macOS receive the “Your connection is not private” error because the root certificate that was used to vouch for UVM sites expired on May 30, 2020. The new root certificate used to validate connections to most uvm.edu sites is not included in macOS versions 10.11 or lower, which is why those systems can’t establish a chain of trust.


This issue can be resolved by upgrading your macOS version to 10.14 or higher using the steps above.
