macOS 10.07 Lion - End of Life

Support Ending December 31, 2019

Apple has announced the launch of its new operating system, macOS 10.15 Catalina in October 2019. In keeping with Apple's release cycle, macOS 10.07 Lion is no longer receiving security updates as of November of 2012.

Our latest fully-supported operating system is macOS Mojave (10.14).

Please note: At this time we do NOT recommend installing Catalina in either beta or final form until our testing is complete. Upgrading prematurely may result in a potential loss of data and performance as a result of incompatible applications. You can stay informed about the progress of our Catalina testing on our macOS Catalina support status page.

As a result, we are phasing out software support for all computers running macOS 10.07 Lion and will end support on December 31, 2019.

What do I need to do?

If you have an SCS-supported computer still running macOS 10.07 Lion, you have the following options:

• Request an upgrade performed by SCSCF Technicians
  If you would like to upgrade your Mac, please request an upgrade performed by our technicians
• Remove SCSCF Software Support
  If you would like to continue to run Lion without SCS software support, please submit a request to remove software support from your computer.
• Retire your computer 
  If you are no longer using this computer or would like to retire it from support, please submit a a request to retire your computer.

Please note: if you choose not to upgrade your computer, it will not receive security patches or functionality updates and our ability to troubleshoot issues will be limited. SCSCF software support charges will be canceled automatically . Additionally, computers identified as security risks may be blocked from the CMU network by the Information Security Office (ISO).
