Casper Admin fails with an error:

The master distribution point (Primary (Software)) could not be mounted.

ITS will tentatively upgrade to Casper 9.93 in October for initial macOS Sierra support and Casper 9.96 (or later) over winter break. Please note with Casper 9.96 support for older OS versions will be going away. JAMF has dropped support for OS X 10.5 and 10.6 and deprecated support for OS X 10.7 and 10.8. JAMF recommends upgrading to OS X 10.9 or later for the best experience. See Deprecations and Removals for more information. Anybody running OS X 10.8 or older should upgrade their Mac to OS X 10.9 or later before ITS upgrades to Casper 9.96 over winter break.

AnyConnect 4.x requires a different license that ISU does not currently have.

Even though Cisco has ended support of AnyConnect 3.x, it still works with macOS Sierra. AnyConnect 3.x is available from

Symantec Endpoint Protection

If you do an in-place upgrade to macOS Sierra with a version of Symantec older than 12.1.6MP6 the OS will disable the kernel extension and display the following error:

Lync For Mac 2011

The system extension “SymInternetSecurity.kext” is not compatible with this version of OS X and can’t be used.

To avoid this scenario, it is best to upgrade to Symantec Endpoint Protection 12.1.6MP6 before doing an in-place upgrade to macOS Sierra, or immediately after upgrading.
