How do I change the iMessage account on my Mac?
I cannot delete it. Notice below that the "-" button is greyed out. Also, when I select it, there are no options in the pane on the right hand side.
The one thing that's weird about this is that this account used to be a non-email account. I have tried to convert everything to use an e-mail username as I was getting confused. Anyway, this is driving me crazy because I can't delete the account, I can't sign out of it. Very frustrated.
Any help would be greatly appreciated.
