MacBook Air Mail
When I click on the mail app on my MacBook, It doesn't open. The word next to the apple in the top left changes to "Mailbox" but the app won't open. If I get a mail notification I can open it, but I can not go back and look at all of my mail. I can get to the mail via my iPhone or through google. I have tried restarting my laptop but it has not been working.
