Problem Statement – Mac OS update to Big Sur OS. Firefox stops working for all websites (including access to PROMIS Portal, PROMIS 4 & PROMIS Classic)
Per our November 17, 2020 Support Advisory, PROMIS users will not be able to access the PROMIS Portal or PROMIS 4 / PROMIS Classic if you upgrade your Mac OS to Big Sur OS. The Big Sur OS update introduces a Firefox browser issue that can only be addressed by updating to the latest version of Firefox, which is not compatible with PROMIS Classic.
Additionally, any new Mac purchased from November 12th 2020 will come with the Big Sur OS, which is not compatible with PROMIS Classic.
Resolution Statement
We are exploring options to offer a workaround to this compatibility issue, however at this time, there is no solution and users who need to access PROMIS Classic from a Mac device should refrain from updating their Mac OS to Big Sur OS.
If you have already upgraded to Big Sur OS and intend to connect to PROMIS Classic, it is our suggestion that you roll back the update to your previous OS by restoring from a backup or reinstalling a previous OS.
