OK, this seems to be a fundamental flaw in OSX. I cannot find how to do this: - I have a MBP and an external monitor and I want to use only one at a time. - I want to use the optimal resolution for each monitor. - It seems the only way to put the dock and menubar in both monitors is by mirroring, but that sets the external monitor at a lower resolution. - I don't want to have to drag the menubar from one to the other. Any solutions?
