Sophos Anti-Virus is ending support for Mac OS X 10.6 (Snow Leopard) and 10.7 (Lion) on October 31, 2015. Computers running those operating systems will stop receiving Sophos updates after that date. Information regarding this change can be found at:
Apple stopped releasing security updates for both OS X 10.6 (in February 2014) and 10.7 (in September 2014), so continuing to run computers with those operating systems on the network is not recommended. IS&T strongly encourages you to upgrade those machines to the latest Mac OS if possible to ensure that they are protected.
