The latest version of the operating system, macOS Sierra, is now available for all college-owned Apple computers. We strongly recommend you go ahead and upgrade to this version since it has several new and enhanced features such as Siri voice-controlled assistant and support for a tabbed interface in more programs as well as added security from the latest updates. Moving to Sierra will keep you compatible with other programs we use on campus. Upgrading is a straightforward process and will take about an hour. Get complete instructions.
