What is the "messagebus" user group?
I recently find a new group in my Mac 's "User & Groups" pref pane.
Anyone know whathappened of my Mac? Is it safe?
MacBook Pro (Retina, 13-inch,Early 2015), OS X Yosemite (10.10.5)
Did you install any software lately that might have something to do dbus package (using Fink, MacPorts, DarwinPorts, Homebrew?)
It looks like some software created a group for some reason.
