Apple macOS 10.12 Sierra – Support Statement

NOTE: Please join one of our subscription services to receive announcements after 11/1/2016.

A new Apple macOS version 10.12, named Sierra, was released yesterday on September 20, 2016.

Please avoid updating supported computers to macOS 10.12. It will not be supported initially for ITS customers. Upgraded computers may not work with University software and services. Customers who need help with Sierra will be offered a reinstallation of El Capitan.

Newly purchased Apple products with macOS 10.12 pre-installed will be downgraded to version 10.11 El Capitan.

An announcement will be made by the University when compatibility has been confirmed.

Q: What if I need a new Mac that must have macOS 10.12?  For instance, if Apple releases new hardware, deprecates old models, and there is no other choice but to use macOS 10.12 , what are the options?

A: Some software may not work with University systems in this scenario.  However, new macOS versions are typically declared compatible with common University software 3 to 4 months past the release date.  If possible, please refrain from purchasing newly revised Mac hardware until then.

Q: Why does it take so long for software releases to be compatible with University systems?

A: The University must be reasonably assured that productivity does not suffer as a result of software incompatibilities.  Some systems use software produced by outside vendors that also must be validated against the new OSX release.  Examples are Cisco AnyConnect VPN, Citrix MyApps, OpenAFS, JAMF Casper Suite, FileMaker Pro (SPEX), DFS, and many more.
