You should see two monitors represented-the MacBook’s display and the ScreenRecycler display (which appears within the VNC client window on the iMac). Open the MacBook Air’s Displays system preference. If needed, enter that address information into the VNC client and, in short order, you should see an image from the MacBook Air appear on the iMac’s screen. ScreenRecyler will tell you the address to use for your connection if it and the VNC client don’t automatically connect over Bonjour. On the iMac (the Mac you’ll use as the display) launch a VNC client (a trial copy of Stein’s $40 JollyFastVNC is included). Launch ScreenRecycler on the MacBook Air after the restart.
#USE MAC AS SECOND MONITOR FOR PC INSTALL#
You’ll be told that you need to install a driver-go right ahead and do that and restart your Mac when prompted. Install ScreenRecycler on the MacBook Air (the Mac you want to project to the other Mac). It works this way: Make sure that both Macs are on the same network. Specifically, try Patrick Stein’s $30 ScreenRecycler ( ). Rather, you use VNC (Virtual Network Computing) over a network to place the image of one Mac’s screen on another screen.

Regrettably, there isn’t (at least not one that doesn’t require a soldering iron and far more skill than I possess). What you likely want to hear is that there’s a way to string a video cable between the MacBook Air and the iMac and have the iMac behave just like an external monitor. I apply the extra consonants to indicate that while it’s possible to project the image of one Mac’s screen on another Mac, it doesn’t work in a way you probably expect. She sees my setup with a laptop and second monitor and wants to know if her iMac can be used as a second monitor. My wife’s running an old iMac G5, and we’d like to move her to a MacBook Air.

Reader David Camp would like to use an iMac’s display as a second monitor.
