macOS 12 Monterey Release Information

Monterey Release Information

Apple's most recent operating system, macOS 12 Monterey, comes pre-installed on new Macs and is available as an upgrade for compatible Macs. For a full listing of new features, please visit the official macOS Monterey information page.

Upgrade to macOS 12 Monterey

As is often the case when new operating systems are first released, there are incompatibilities with a number of widely used applications for campus Mac users. OIT feels Apple has addressed the most common issues with the new operating system and therefore faculty, staff, and students should feel free to upgrade Apple devices to macOS 12 Monterey.

OIT recommends that before upgrading to any new operating system, ensure your most used applications are compatible by checking the compatibility testing information below, or by contacting the vendor directly.

If you buy a new mac or 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 schedule an appointment to bring your computer to the OIT Buff Techs Walk-In Center, contact Dedicated Desktop Support, or contact the IT Service Center at 303-735-4357 or

Dedicated Desktop Support Customers

Mac systems that are enrolled in Dedicated Desktop Support will be prevented from upgrading to macOS 12 Monterey as OIT works to resolve compatibility issues with standard applications and campus IT infrastructure. In the meantime, if you are supported by DDS and are interested in upgrading or have any questions, please contact your DDS Technician.

Known Compatibility Issues

USB 3.0 functionality 

Some users running macOS Monterey have reported issues using USB-C hubs and docks. There have been several reports on Reddit, Apple's Developer Forums, and Apple's Support Communities about macOS Monterey and USB 3.0 hubs compatibility. OIT has confirmed the problem exists at least in Remote Capable Classrooms, but does not seem to be affecting a large number of users on campus. We will continue testing and update this page if this determination changes. 

Compatibility Testing

Compatibility of macOS 12 Monterey is being monitored by OIT. If additional compatibility issues with campus services and supported software arise, we will report the results on this page. Before you upgrade to Monterey, check this page to ensure compatibility with software, services, and systems you use the most.
