Apple Macintosh users should upgrade systems to Mac OS X 10.8 or later

2:58 p.m., March 3, 2015--With the release of Mac OS X 10.10 last year, Apple announced that versions 10.7 and earlier would no longer be supported. Using a version of Mac OS that is not supported puts the security of your computer, your computer accounts, and the information stored on your computer at risk. 

Additionally, a planned upgrade to increase the security of the VPN software used to securely access confidential UD information will not work with versions previous to Mac OS X 10.8.
