Apple plans to release its latest version of OS X, El Capitan, on September 30. We currently support the OS X version known as Yosemite and plan to support El Capitan by June 2016, after the end of the academic year. Last year, faculty and staff members were unable to log into their computers or encountered data loss after upgrading to Yosemite. To avoid such issues, please decline any request from Apple to upgrade to El Capitan. If this affects your teaching and research negatively, please contact us by writing to AskIT@amherst.edu.
