Mojave Release Information

Apple's most recent operating system, macOS 10.14 Mojave, is available to download. For a full listing of new features, please visit the official macOS Mojave information page.

Recommendation: Upgrade

As with many new operating system releases, there are initially a number of incompatibilities with commonly used applications, and Mojave was no exception. At the time of it's release, Mojave had significant compatibility issues, however these have been addressed appropriately and OIT now recommends that all Mac users upgrade to the most recent release of Mojave.

Please Note: If you choose to upgrade and run into problems that cannot be resolved, you may need to revert to an earlier version of macOS, which entails backing up your files and doing a fresh install. For assistance, please bring your computer to an OIT Buff Techs Walk-In Center, contact Dedicated Desktop Support, or contact the IT Service Center at 303-735-4357 (5-HELP) or

Compatibility Testing

New Privacy Restrictions

The primary change OIT has observed in compatibility testing is due to new privacy restrictions for how applications access the camera or microphone, user data including Contacts, Calendars, and Photos, as well as control over another application or specific system processes. These privacy restrictions result in numerous prompts with an application's request to access these areas. 

If an application cannot correctly prompt the user, the request may fail silently or cause the application to become unresponsive. If a user chooses Don't Allow from a prompt, the application or process will be prevented from accessing the resource. 

Users can re-enable access by navigating to System Preferences > Security & Privacy > Privacy and enable the option on the sub panel in question. For example, the following screenshot shows Google Software Update service requesting Accessibility permissions.
