You can disable the Messages app on Mac by signing out, turning off notifications, or removing it from your dock — depending on how completely you want to stop using it

The Messages app on Mac stays active by default, which means it syncs with your iPhone and iPad, receives notifications, and launches automatically when you restart your computer. If you want to stop using Messages altogether, you have three main routes: sign out of your Apple ID within the app (which stops syncing but keeps the app installed), disable notifications so you don't see alerts, or remove the app from your dock so it's out of sight. Which one makes sense depends on whether you want to keep Messages installed for occasional use, silence it completely, or make it harder to open by accident.

Key Takeaways

  • Signing out of your Apple ID in Messages stops it from syncing with your other devices and receiving new messages, but the app stays on your Mac.
  • Disabling notifications in System Settings silences alerts without removing the app or signing you out.
  • Removing Messages from your dock makes it less visible, but you can still open it from Applications or Spotlight if you need it later.
  • If you want to uninstall Messages completely, you cannot delete it through the normal trash method because it is a system app, but you can hide it or use third-party tools.

Sign out of Messages to stop syncing across devices

Signing out of your Apple ID in Messages is the most straightforward way to stop the app from receiving new messages and syncing with your iPhone or iPad. Open Messages from your Applications folder or by searching in Spotlight. Go to the menu bar at the top and click Messages, then select Settings (or Preferences on older macOS versions). Click the Accounts tab on the left side.

You will see your Apple ID listed with a checkbox next to "Enable this account." Uncheck that box, or click the minus button below the account list to remove it entirely. When you uncheck the box, Messages stops receiving new messages and stops syncing with your other devices, but the app itself remains installed on your Mac. If you sign back in later, your message history will still be there.

Turn off notifications to silence alerts without removing the app

If you want to keep Messages installed and signed in but stop seeing notifications, you can disable them in System Settings. Click the Apple menu in the top-left corner, then select System Settings. Click Notifications in the left sidebar. Scroll down and find Messages in the list of apps.

Click on Messages and toggle off Allow notifications. You can also customize which types of notifications appear — for example, you might turn off sound and badge notifications but keep banner notifications visible. With notifications disabled, Messages will still receive and store new messages, but you won't see alerts on your screen, hear sounds, or see badge numbers on the app icon. You will only see new messages when you open the app yourself.

Remove Messages from your dock for a cleaner view

Removing Messages from your dock does not disable the app or stop it from running, but it makes it less visible and less likely to open by accident. Right-click on the Messages icon in your dock at the bottom of your screen. A menu will appear with options. Click Remove from Dock.

The app is still installed on your Mac and will still run in the background if it is signed in. You can still open it by going to Applications, using Spotlight (press Command + Space and type "Messages"), or by clicking it in Launchpad. This approach is useful if you want to keep Messages available but reduce how often you think about it or accidentally launch it.

Prevent Messages from launching automatically at startup

By default, Messages launches when you restart your Mac if it was open the last time you shut down. You can stop this by opening System Settings, clicking General in the left sidebar, then clicking Login Items. Look for Messages in the "Open at Login" section and click the minus button to remove it.

You can also prevent Messages from reopening windows from your last session. Open Messages, go to Messages in the menu bar, click Settings, then click the General tab. Uncheck Restore windows when quitting and re-opening Messages. Now when you close Messages and reopen it, it will start fresh without loading your previous conversation windows.

Understand what happens when you disable Messages

If you sign out of Messages, you will stop receiving new messages on your Mac, but people can still send you messages — they will just arrive on your iPhone or iPad instead. Your message history on your Mac will remain stored locally unless you delete it manually. If you disable notifications but stay signed in, Messages continues to receive and store messages; you simply won't be alerted to them.

If you remove Messages from your dock or prevent it from launching at startup, the app is still running in the background and still syncing if you are signed in. The only way to fully stop Messages from running is to sign out of your Apple ID within the app. You cannot uninstall Messages through the trash because it is a system app built into macOS, though some users use third-party tools like AppCleaner to remove it more thoroughly.

Frequently Asked Questions

Will people know I have disabled Messages on my Mac?

No. If you sign out or disable notifications, people will not see any indication that you have done so. They can still send you messages; the messages will simply arrive on your other devices or sit unread in Messages until you sign back in. There is no "read receipt" or status that shows whether you have the app active.

Can I delete Messages completely from my Mac?

Messages is a system app, so you cannot delete it through the normal trash method. You can sign out, disable notifications, and remove it from your dock, which effectively hides it from view. Some users use third-party uninstaller apps, but Apple does not support removing system apps, and doing so can cause problems with your Mac.

If I sign out of Messages, will my message history disappear?

No. Your message history stays stored on your Mac even after you sign out. When you sign back in with the same Apple ID, your messages will still be there. Signing out only stops new messages from arriving and syncing with your other devices.

Does disabling Messages affect iMessage on my iPhone?

No. Messages on your Mac and iMessage on your iPhone are separate. Disabling Messages on your Mac does not change how iMessage works on your phone. People can still reach you through iMessage on your iPhone even if you have signed out of Messages on your Mac.

Why does Messages keep launching even after I close it?

Messages may be set to reopen at login or to restore windows from your last session. Check System Settings under General > Login Items to remove Messages from startup, and check Messages Settings under the General tab to uncheck "Restore windows when quitting and re-opening Messages."
