    My macbook shows a second display in System Preferences->Display. There is no second display attached. I have clicked "Detect Displays" and rebooted, with no change.
    The annoying part, is that my mouse keeps going to the "other" display. I would use "Mirror" to eliminate the symptoms, but the available resolutions are low and not wide-screen. To get around it for now I just dragged the "other" display to the bottom corner of my macbook's display, so that my mouse doesn't wander over there.
    Do any of you have any thoughts about something I could try?
    Thanks,
    Josh

    Try resetting the SMC. Apple website will show you how.

    My Mac once got its knickers in a twist, it didn't know which was the internal and which the external monitor. SMC reset fixed it. It sounds like you might have a similar problem.
