Mac OS X v10.7 (Lion) at Stanford

Security Notice

In late February 2014, Apple announced a major security flaw affecting Macintosh computers running OS X 10.7, 10.8, and 10.9. Left unpatched, email, web site traffic, banking transactions, passwords, and other data transmitted to and from these devices are susceptible to being intercepted. Stanford University's Information Security Office strongly urges you to update your system immediately.

To update your system, go to the Apple menu and click Software Update. Install any available Safari updates or security updates. A restart will be required.

Obtaining Lion

OS X version 10.7, nicknamed Lion, was released on July 20, 2011. With this release, Apple is moving to a new distribution model; the new software will be available for download at the Mac App Store. The cost for Lion is $29.99 when purchased by an individual through the Mac App Store.

Volume licenses (20 user minimum) for the Mac App Store are $15/license. These can be purchased through SmartMart.

For more information on the new OS, please visit Apple's new OS X Lion page.

Software compatibility

Users are encouraged to read this section in full to make sure the software they need to use is compatible with Lion before upgrading. This section will be updated frequently, so please check back often in the first few weeks following Lion's release.  See this external site for a longer list of applications.

Essential Stanford Software (ESS)

  • Stanford Desktop Tools: SDT 3.1.3 has been released and provides support for Lion.  Users should upgrade to this version prior to upgrading to Lion.
  • Sophos Anti-Virus: Sophos Anti-Virus 7.3.1 (available from ESS) is compatible with Lion. Sophos should have autoupdated to this version for all existing installs.
  • Tivoli Endpoint Manager/Bigfix:  Internal testing indicates the current version is compatible with Lion.  We are awaiting official word from IBM.
  • Fetch:  Fetch 5.7 (available from ESS) is compatible with Lion.

Administrative Systems applications

See Browser Recommendations for Administrative Applications for the latest information on browser compatibility with administrative applications in use at Stanford.

Other applications

  • OpenAFS: OpenAFS 1.6 has been released and provides official support for Lion.  Users who have been using OpenAFS 1.4.x and upgrade their machine to Lion should upgrade OpenAFS to 1.6 as soon as possible to avoid slow performance of the OpenAFS client.
  • PGP:  Assumed not to be compatible with Lion.  PGP users should not upgrade to Lion until an officially supported version of PGP Desktop is available.
  • Eudora:  Eudora and any other older applications that are compiled to run on PowerPC chips (Carbon apps) will not run.
  • Microsoft Office 2008: The installer for Microsoft Office 2008 will not run. Existing installations of Office 2008 will work fine.
  • Vmware Fusion:  Vmware Fusion will generally work, with some limitations.  See Vmware's page for full information.
