In the past, I used iChat + Chax for instant messaging on my Show Leopard. Then I switched to Adium but iChat seems to be started automatically though I removed it from login items.

ps ax | grep iChat
  188   ??  S      1:21.91 /System/Library/Frameworks/IMCore.framework/ -psn_0_94231
67977   ??  S      0:00.31 /System/Library/Frameworks/IMCore.framework/ -psn_0_29355005

Why iChatAgent is still started? How to completely disable it?

I have the feeling this has something to do with FaceTime maybe? At least I think FaceTime starts automatically and uses iChat in the background. – slhck Apr 23 '11 at 10:02
@slhck: I don't think so. At least on my system (10.6.7), iChat or iChatAgent don't show up on the process list when using FaceTime. – ayaz Apr 23 '11 at 10:11

Make sure you also removed the iChat Menu Extra that looks like a speech bubble by Command-dragging it from the menubar. Activating this menu item does launch the iChatAgent. Alternatively, disable it in iChat's preferences:

You might need to log out and back in for iChatAgent to quit, or just kill it.

Thanks a lot! It seems working. Pretty strange behavior. – Stas Apr 23 '11 at 13:30
