Q: Messages App on Mac very Slow

It takes forever to write(being recognized by the app) and send a message. This issue only started recently but it's becoming more and more so. It's very frustrating so please help!

MacBook Pro (Retina, 13-inch,Early 2015), OS X El Capitan (10.11.3)

    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.

     

    If that doesn’t work, repeat the above but delete the com.apple.imagent.plist

    Hi,

     

    IN the Edit Menu check the Spelling and Grammar settings.

    If these appear to be correct, check the language used  in the "Show Spelling and Grammar".

     

     

    There may be issues if your keyboard language choice and the spelling choice don't match.

    Eric's fix, above, worked for me, but i had to delete all the iChat, imessage, and imsystem plist files.

    messages.app is usable again!
