I use Mountain Lion (10.8.3) Messages exclusively to monitor text messages sent to my cell phone. When I first start my computer or login Messages is hidden (I don't want it in my dock) and if I receive a text message I get a banner alert from notification center. If I open the message I enter the Messages application and the running application shows up in my dock.
What I would like to do is have Messages behave as it does when I first start the computer (receiving notifications but not visible in the dock as running) all of the time (I assume it's running in the background somehow).
If I click 'Hide' on the Messages icon in the doc it remains visible, and if I quit messages entirely after reading a message I stop receiving notifications.
I have tried editing its
Info.plist to include
as suggested in the Hide a running app from dock thread, but the behavior remains the same.
