Is there a way to globally change the appearance of messages in Messages (Beta) for OS X?
In OS X Messages (Beta), the appearance of a given message thread can be changed by selecting submenu options from the View > Messages menu item; but this only applies to the currently displayed message. Is there a way to configure these options as defaults for (all) new threads?
Solution 1:
Yes, there is:
Messages > Preferences > Messages
You can set the look and feel for incoming and outgoing messages here.
