• SwitchResX always says a "Reboot is needed"
    Versions prior to 4.0.2 would continue to indicate that a reboot is needed to enable a resolution.
    If you already rebooted, this means the resolution was not activated at all, and can't be, because MacOS X refuses to activate it.
    Versions 4.0.2 and above correctly reports the status as "Invalid" or "Not activated".
