Releases: fcanas/mirror-displays
Missing Link
Version 1.2 adds manual display linking.
For example: if you have three monitors you can mirror the first two like this mirror -l 0 1, giving you two mirrored displays and a third display un-mirrored. Unlinking is as easy as enabling or disabling mirroring across all monitors, i.e. mirror -on or mirror -off.
Revival
Mirror Displays App
Mirror Displays
This is a simple application to toggle between mirrored and extended desktop modes for the mac. It's the easiest way to turn on, or turn off mirroring displays on a Mac. You can put it in your dock for an easy-access switch, or activate it with Quicksilver, Quick Search Box or Spotlight. When you run it, it will bounce in the doc once or twice and change the display mirroring settings. There is no user interface, and only makes the change in settings if an external monitor is attached.
Mirror Tool
The command line tool is good for giving shell-scripts the power to control display mirroring and opens up the possibility of controlling mirroring remotely over ssh. In addition to the default toggle mode, it can turn mirroring on or off regardless of what the current state of mirroring is, and can report the current mirroring status without changing anything.

-h Print this usage and exit.
-t Toggle mirroring (default behavior)
-on Turn Mirroring On
