If you are running a dual-display setup, you can easily adjust the primary display monitor in Mac OS X. When would you want to do this? For example, if you have a MacBook Pro 13″ hooked up to a larger external display, and you want the external display with it’s higher resolution to become the primary display, and your MacBook Pro with it’s smaller resolution to become the secondary display. This is just a matter of settings adjustments and it only takes a minute to configure, though it’s not particularly obvious at first glance.
