Mac OS X 10.11 El Capitan

On September 30, 2015, Apple released OS X El Capitan (10.11.0). UIT is actively testing El Capitan to determine UH compatibility. Until we are able to validate software and UH compatibility, as well as third party vendors, we are not able to provide full support for OS X El Capitan.

Until the necessary testing is complete, we strongly encourage all UH students, faculty, and staff to avoid upgrading to ensure our ability to provide support for OS X El Capitan, third party software, and UIT systems.

UIT encourages all users to work with their IT managers before upgrading to ensure 3rd party software compatibility. Please work with your IT manager to ensure that any pertinent software is compatible before updating your device.

Why?

Each IT department is required to perform different tasks, and have many distinct and separate needs. Administrators can test the software with regard to the departments needs, and determine whether to upgrade based on their environment.

Disclaimer: A technical change in 10.11 is as follows - El Capitan has made significant changes to security known as System Integrity Protection, which applies a security policy to all active system processes. App store software follows a more restrictive policy and aren't impacted. Third party vendors will be greatly impacted, as they will likely have to redesign their application software to accommodate the system software i.e., it may take some time for vendors to accommodate this change, so it is encouraged to examine business critical software and vendor known issues to avoid software incompatibility, etc...
