Messages on MacPro

[dteddy]

Hello everyone,

I'm having an issue with my Messages app on my Mac Pro. I used to use it all the time and stopped for a while and now when I sign on I lost all of my contacts and it won't let me send or receive new messages. Any help would be greatly appreciated. Thanks

Sign out of iMessage, reboot your Mac and then sign back in to iMessage. Make sure that your Mac has Internet access.
