Upgrading to macOS 10.15 Catalina

macOS Catalina (10.15)

macOS Catalina was released on October 7, 2019. CAS has been working for months testing macOS Catalina with our software and policies to verify everything works as it should after upgrading. We've compiled a full list of supported/unsupported versions of macOS.

Some Things You Should Know

Starting with macOS Catalina, 32-bit apps are no longer compatible with macOS. Please verify that any critical apps are updated to 64-bit or contact the software developer about obtaining a 64-bit version.

Catalina in particular is known to have significantly more notifications and settings that the end user (that's you) will have to "Allow" after upgrading or when installing new software.

In newer operating system versions, Apple requires that the end user (you) can be the only one to approve any applications to use the microphone, camera, or perform screen recording. This has a minor affect on our users, as you will have to approve for CAS Remote to screen record before a technician can remote in to help with any needs. The first time the application is ran, it should prompt you to approve this and even take you to the exact spot in System Preferences where you will need to approve at. Don't forget to checkout our documentation on approving CAS Remote.

Eligible Devices

iMac late 2012 and newer
MacBook Pro mid 2012 and newer
MacBook Air mid 2012 and newer

Apple maintains a list of all devices that are compatable with macOS Catalina.

Upgrade Timeline

Beginning on May 20, 2020, CAS will begin deploying macOS Catalina to elgible computers as a required operating system upgrade to devices currently on unsupported versions of macOS. Keeping your computer's operating system up to date helps ensure any security vulnerabilities to your system have been patched. Moreover, it helps to ensure your computer will function properly with CAS supported software.

CAS plans to upgrade in phases starting from older macOS versions and then working our way forwards to newer versions. Exact system upgrade dates will be emailed to individual users to inform them when they can expect the upcoming change.

How to Upgrade Now

CAS recommends completing the following before starting the upgrade process:

  • Make sure to back up any important files beforehand! This process does not wipe the computer, but if the computer fails during the upgrade there is a chance of data loss. Consider using your 1 TB cloud storage space on OneDrive provided by UNT.
  • Keep the computer connected to power during the entire upgrade.
  • Make sure you have a stable internet connection during the entire upgrade.

When ready, open Self Service, find Upgrade to macOS Catalina and select install. The upgrade will take 30-60 minutes and your computer will be unusable during this time.

If the upgrade fails for any reason, please contact our Service Desk.

Note: If you are upgrading from OS X Lion or Mountain Lion, please make our Service Desk aware beforehand as your upgrade process will be different.

Get an Exception

If your computer can not be upgraded to macOS Catalina due to research equipment or software incompatibilities, you may qualify for a computer exception. If this is the case for you, please send CAS an email outlining the equipment/software that would prevent the upgrade, your current operating system, as well as the UNT asset tag on the computer. Each request will be handled on a case by case basis.
