Introduction

Starting in mid‑February 2026, the Microsoft 365 apps for Mac suite installer a shim for the Microsoft 365 Copilot app. This change helps organizations more easily deploy the Microsoft 365 Copilot Mac app by enabling users to download the full application directly from the shim.

How this affects your organization

  • Users will be able to download and install the full Microsoft 365 Copilot app by opening the shim app from the Applications folder.

  • Confirm that devices meet the minimum requirement of macOS 14.0 (Sonoma) or later.
