Mojave Release Information

Apple's most recent operating system, macOS 10.14 Mojave, will be available September 24, 2018. For a full listing of new features, please visit the official macOS Mojave information page.

Recommendation: Wait to Upgrade

As with many new operating system releases, there are initially a number of incompatibilities with commonly used applications, and Mojave is no exception. Due to significant compatibility issues, some of which are outlined below, OIT highly recommends all users (even early adopters) wait to upgrade.

Mac systems that are enrolled in Dedicated Desktop Support will temporarily be prevented from upgrading to macOS 10.14 Mojave, as OIT works to resolve significant compatibility issues with standard applications and campus IT infrastructure. In the meantime, DDS users will see a notification to that effect if they attempt to run the installer themselves.

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 help@colorado.edu.

Compatibility Testing

New Privacy Restrictions

The primary problem 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. For example: 

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 permanently prevented from accessing the resource. Some prompts are not clear why the request is necessary for an application, nor is it always easy to find where to reverse and allow the application to access the resource.

In general, 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.

Applications with known Issues

Application Issue
System Center Endpoint Protection (SCEP) for Mac

SCEP requests access to system preferences and other user libraries, but frequently locks up during/after the prompt is active. This results in a lack of antivirus coverage. 

Microsoft Office 365 OneDrive Does not give user privacy prompts, but the menu within the application is broken in Mojave.
