FaceTime and Messages

Greetings DJMrSparkZ,

Thanks for visiting the Apple Support Communities! I understand you're unable to sign in to iMessage and FaceTime on your MacBook Pro, as you mentioned you're receiving an alert that your Apple ID or password is incorrect.

The following guide will help you to reset your Apple ID password: If you forgot your Apple ID password

If the behavior persists after resetting the password for your Apple ID, then I suggest following the steps outlined within the "Check your Apple ID" section of the following guide: If you can't sign in to your iMessage account or FaceTime on your Mac

Let me know how it goes from here.

Cheers.

Might be a corrupt .plist.

Do a backup, preferably 2 backups on 2 separate drives.

Quit the application.

Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J.  When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder.  Select Library. Then go to Preferences/com.apple.iChat.plist.  Move the .plist to your desktop.

Restart the computer, open the application, and test. If it works okay, delete the plist from the desktop.

If the application is the same, return the .plist to where you got it from, overwriting the newer one.

Thanks to leonie for some information contained in this.

Were you able to sign into Messages/FaceTime while booted into the Safe Mode? I don't see anything in the report that should be a problem. Reboot normally and try to sign in again. If it still doesn't work, try running the report again.

See if you can open preferences by using command - , (comma).

You are welcome. I agree with ***?!
