Messages app on mac isn't opening

Hi madisonle123,

Since both the Messages app and FaceTime does not open on your iPhone, we recommend that you try the steps here: If an app on your iPhone or iPad stops responding, closes unexpectedly, or won’t open - Apple Support

To perform the steps in the article we suggested above, click and open the link, read the subheadings below, and try each step.

1) Close and reopen the app

Force the app to close. Then open the app to see if it works as expected.

2) Restart your device

Restart your iPhone or restart your iPad. Then open the app to see if it works as expected.

3) Check for updates

To see if updates are available for the app, open the App Store, tap your profile icon, then scroll down to see if updates are available. If updates aren't available for the app, update the software on your iPhone or iPad.

4) Delete the app, then redownload it

Delete the app. When you do this, you might lose data that was stored in the app. Then redownload the app. Then check to see if the problem with the app is fixed.

The reason why we are recommending the steps above is because they will show you what to do if an app on your iPhone or iPad doesn't work as expected.

If you’re still experiencing the same issue, then we suggest that you contact Apple Support directly so that they can work with you to find a solution. You can reach them by clicking here: Apple Support or calling the most local number in your region: Contact Apple for support and service. Thank you for participating in the Apple Support Communities. Cheers!
