I am trying to open Facebook Messenger on my app. It opens so far as I can see my contacts, but before I can see my messages it closes. Then Terminal gives me this message: Last login: Fri Dec 3 08:49:11 on ttys001 /Applications/Messenger.app/Contents/MacOS/Messenger ; exit; [myusername]@iMac ~ % /Applications/Messenger.app/Contents/MacOS/Messenger ; exit; zsh: abort /Applications/Messenger.app/Contents/MacOS/Messenger Saving session... ...copying shared history... ...saving history...truncating history files... ...completed. [Process completed] Any suggestions how to open this app.
