OS: Sierra 10.12.2
System: Macbook11,3 MacBook Pro (Retina, 15-inch, Late 2013) with a 2.3 GHz Intel Core i7 and 16 GB TAM.
I cannot use Messages to sign into my iMessage account. I get:
An error occurred during authentication.
This has been for over a month and I have gone to the Apple store and called support. Support passed it to engineering and it faded away. This is the error:
All of the ports seem to be blocked, or at least they do not show up on a port scan out of Network Utility. When I use lsof -i | grep http
all I see are Chrome windows which happen to be open.
I left off last time with my pf file being disabled. So that's not it. Any ideas?
Note: I was troubleshooting earlier and made some leeway. This is not the same question as earlier, it has advanced. I am now specifically looking for terminal commands.
