What OS Versions are Supported?

• Windows 10 22H2 (build 19045)
• Windows 10 21H2 (build 19044)
• Windows 11 23H2 (build 22631)
• Windows 11 24H2 (build 26100)
• macOS 13 Ventura
• macOS 14 Sonoma
• macOS 15 Sequoia

Typically, the three most recent major OS versions are supported, dependent on vendor support (Windows | macOS). Support for newly released major versions of OSes will lag slightly behind availability to the public. This allows DoIT Support time to evaluate the new OS and perform compatibility testing with existing software before approving the new OS. 

Why is the supported OS policy important?

Some of the most important reasons to remain up to date are:

• Improved security
• Access to latest features
• Better compatibility
• Better device performance
• Vendor support
• Increased productivity and efficiency

What happens if my device is not on a supported OS version?

DoIT has many tools and methods to ensure devices stay up to date and will never fall into this category. If you have a system that is not on a supported OS version and are unsure how to update it, please let us know and we can assist in getting the system up to date. If a system is too old to receive a supported OS version, we will likely recommend it be replaced. If you have received communication from Departmental Support that you have out of support devices, please see this documentation on how to handle that.

What does it mean to be Unsupported?

When a machine falls into the unsupported category, we will provide best effort support, but no extraordinary effort will be made to ensure compatibility for an OS that is no longer supported.

• If a problem is determined to be due to old OS version, we will recommend an upgrade
• The machine will remain enrolled in and receive any compatible Managed Security Layer services
• We will not make any effort to deny updates or deployments due to unsupported OS, but if an update or deployment fails on these machines, we will not spend extra effort to ensure they receive them
• If hardware is unable to support one of the approved OS versions, we will recommend replacement

If you have any questions or concerns please contact DoIT Support.
