OS Compatibility Testing - macOS 26 (Tahoe)

This article will detail the results of DoIT's compatibility testing of macOS 26 (Tahoe).

Testing Details

Testing is being conducted using macOS 26.0 on a 2020 13-inch M1 MacBook Pro, a 2023 M2 Mac Mini, and a Mac VM. 

Recommendation

macOS 26 is currently supported on Departmental Support-managed systems per DoIT Support's supported OS policy.

See Apple Silicon-specific compatibility here.

Note: Upgrading to macOS 26 (Tahoe) may reset security allowances for some applications. This will cause dialogue boxes to pop up asking you to "Allow" certain apps again even if you've already done so in the past. This is a one-time process.
