Meta has confirmed the closure of the applications of Messenger for Mac and Windows, a move that ends the desktop client and focuses the service on the web and mobile. Starting December 15, it will no longer be possible to log in to these apps, and when you try, you will be redirected to Facebook.com or Messenger.com to continue your conversations.
The change will be gradual: those who still use the application will see a notice within the client itself that activates a 60-day adaptation period. During this period the app will continue to work, but it is advisable to prepare the transition as soon as possible; mobile versions of iOS and Android are not affected and will continue to operate normally.
Dates and how the closing will be

Meta has removed the app from official stores —Mac App Store and Microsoft Store— to prevent new downloads, and maintains a phased shutdown among active users. Once the 60-day window expires, the app will no longer be usable and will not allow login.
The company recommends uninstall the app Once it becomes unusable, this will prevent confusion and free up resources. From that point on, your messages will be accessed exclusively through your browser or mobile device.
The redirection will vary depending on the account typeIf you're using Messenger linked to Facebook, you'll be taken to Facebook.com; if you're using Messenger without a Facebook account, you'll be directed to Messenger.com. In both cases, the service's core web features will be maintained.
As for the product's trajectory, the Messenger service became popular in the last decade and the desktop app launched in 2020. In 2024, Meta took an intermediate step on macOS by replacing the native client with a progressive web application (PWA), and now the transition ends with the final closure of the desktop apps.
How to keep your chats safe

To avoid information loss, Meta asks to activate the secure storage and set a PIN from the desktop app before closing. This setting ensures that your history, including end-to-end encrypted chats, remains available on the web and mobile versions after the migration.
- Open Messenger on your computer and click the icon profile.
- Walk into Privacy & Security and select End-to-end encrypted chats.
- Access to Message storage and activate secure storage.
- Create and confirm a PIN to protect access to conversations.
- Verify that the option is enabled before the deadline.
If you don't enable this feature in time, some of your desktop-only history may not sync properly. Enabling it in advance ensures that all messages are protected and available across platforms.
Meta remembers that the end-to-end encryption Protect the content of your conversations so that only you and your contacts can read or listen to them; Nobody, not even Meta, has access to those messages when this protection is active.
