Apple Core Root is just getting more and more sighy.
How difficult is it to send a message? Pretty darn hard when Messages.app just gets AWOL.
I have tried several times, and each time it is the same: 3 or 4 messages are sent (pictures), then all fail successively. ONE
When this happens, there is no outgoing network activity and the Messages.app progress bar just stops in place. Otherwise, Messages.app behaves normally and text messages send OK. Worse, there is intense incoming (download) network activity (up to 14 MB / sec) —WTF?
This is on wired Ethernet and everything else works. Recipients (4) all online with good reception of cells (at home I sent some pictures to the family).
Messages.app fails to send all pictures, no network activity
Messages.app fails to send all pictures after 2-4 pictures have been sent
