"Messages from iPhone" icon keeps appearing in Dock
I went through this with Yosemite as well. Don't recall which step(s) resolved it, but things were fine until I upgraded to El Capitan. The 'Message' icon will not stop appearing on the left side of my Dock bar. I've done the following based on advice found in searches:
- opened iMessage and disabled my account (which is what all of our mobile devices are logged in using)
- opened System Preferences...Notifications, clicked 'Messages' on the left pane, selected 'None' and unchecked all 5 checkboxes
- rebooted
Inevitably, as soon as someone in the family gets a text, the "Messages from iPhone" thumbnail reappears. It's ridiculous, and it's maddening.
Hopefully someone has a solution...
Thanks
iMac, OS X El Capitan (10.11.5)
