Mail Preferences
When I open preferences in mail app. I get a blank page that says Signature. What is wrong with the app? I have looked at other answers to this question and it seems so complicated that I don't want to begin the process because I expect it will create even more problems. Is there a simple answer or do I just give up and leave it? I've been using Apple since 1982 seems you have to be a computer technician to do anything on a Mac. It probably won't be much longer till I can't even use Apple any more. Now it's telling me to choose a topic but there is no way to do that. How do I disconnect from the Matrix?
