macOS Licensing

This article applies to: Software Licensing


Apple no longer offers educational licensing for macOS (previously Mac OS X). 

macOS installers are no longer available from the Cornell Store or from CU Software.

Beginning with Mac OS X 10.9 (Mavericks), upgrades have been available free of charge from the Mac App Store. You computer must meet the minimum specifications to run a particular version of macOS.

Supported Releases

The current release is macOS 10.13 (High Sierra).

Apple still supports the following versions:

  • macOS 10.12 (Sierra) 
  • mac OS X 10.11 (El Capitan)

Earlier Versions of macOS

Upgrading via Mac App Store

Apple no longer supports versions of Mac OS X earlier than 10.11 (El Capitan). If you are running an earlier version of Mac OS X, we recommend that you upgrade to a supported version via the Mac App Store.  Upgrading is free.

CIT no longer supports services running under versions of macOS earlier than 10.10 (Yosemite), and cannot guarantee that any particular IT product or service will function properly on an older version of Mac OS X. 

If you are running an older version of the operating system, you should upgrade to a supported version of macOS. More information about upgrading to the current release of Mac OS X is available at Apple.

Upgrading to Mac OS 10.6

Your Mac must be running Mac OS X 10.6 "Snow Leopard" to be able to use the Mac App Store and upgrade your OS via that channel.  If you are running a Mac with Mac OS X 10.5 or earlier, you will need first to upgrade to 10.6. You can order Mac OS X 10.6 "Snow Leopard" DVD online directly from Apple.  

Please note that Snow Leopard was released in 2009. Even if your computer meets minimum hardware specification to run a contemporary version of macOS, if your computer is running Mac OS X 10.5 or earlier, you will likely not be pleased with your Mac's performance when trying to run a supported version of macOS. For computers of that age, we recommend that you purchase a new computer rather than trying to upgrade your Mac's operating system.

Please contact us if you have any questions or if we can be of any further assistance.
