Problems accessing U of T websites from older versions of MacOS

As the result of recent security certificate updates for a number of U of T websites, we have received reports from people running Mac OS El Capitan (10.11.x) or older having issues loading those websites.

Sites that may not be reachable include but are not limited to:

  • U of T email (UTORmail & UTmail+)
  • Quercus
  • Acorn
  • Some library resources sites

Please note: these are end-of-life operating systems no longer supported by Apple and we cannot ensure access to U of T websites on them.
