Using my IPAD as an extended display using AirDisplay.I couldn't use AirDisplay at McDonald's or Starbuck's. The wi-fi blocked local traffic. So - this is my work-around.
In a nutshell:
- Enabled Bluetooth on both and connected my IPAD to my Mac.
- Started AirDisplay on both and connected.
- When it started up, my Mac's display shrunk to the size of my IPAD.
- System preferences (on my Mac)
- Arrangement - un-check 'Mirror Displays' and position the small window.
