Summary

Microsoft Teams will stop desktop client updates for macOS 13 starting May 2026, with upgrade notifications in June and blocking access by mid-July. Users must upgrade macOS or use Teams on the web. Organizations should identify affected devices, plan upgrades, and prepare users and support teams accordingly.

Details

Introduction

To maintain security, performance, and compatibility with newer macOS capabilities, Microsoft Teams will end support for desktop client updates on macOS 13 (Ventura). This ensures continued delivery of modern features and security updates on supported operating systems.

When this will happen:

  • May 2026: Updates stop for macOS 13
  • Mid-June 2026: Upgrade notifications begin
  • Mid-July 2026: Blocking experience introduced

How this affects your organization:

Who is affected:

  • Users on Teams desktop client on macOS 13
  • IT admins managing macOS devices

What will happen:

  • Teams desktop on macOS 13 will no longer receive updates starting May 2026.
  • Users will see in-app upgrade notifications beginning in mid-June 2026.
  • Users will encounter a blocking screen in mid-July 2026 preventing continued use of the desktop client.
  • Users must either:
    • Upgrade to a supported macOS version, or
    • Use Teams via a supported web browser
  • This change is automatic and cannot be disabled by admins.
  • Organizations that do not upgrade devices may experience temporary productivity or support impacts.

What you can do to prepare:

  • Identify devices running macOS 13.
  • Plan OS upgrades before mid-July 2026.
  • Communicate changes to users.
  • Prepare helpdesk teams.
  • Update compliance policies as needed.
  • Provide guidance to use Teams on the web if needed.

Compliance considerations:

No compliance considerations identified, review as appropriate for your organization.
