  1. Thank you for this. Not only was it hard to find a solution that explains what can be done when you cannot even open the Messages app, but Apple support couldn’t figure it out. My issue was that someone essentially sent me a few megabytes of emoji, and it completely hung the app. Messages would not open. I tired deleting the messages, but couldn’t find all the locations around the Library. After kicking out all the things from the list you have here, I’m back in.
