Setting Up Extended Desktop
I am trying to set up an extended desktop for my iMac. The operating system on it is 10.6.8 and I am trying to set it up so that the extended desktop utilizes my Macbook Pro system 10.7.5. I have the thunderbolt cable and have connected it to both computers and tried the following:
System Preferences -> Displays -> Arrangement
However, when I go into system preferences there is no option under displays for arrangement. What am I doing wrong or what should I be doing to make this work? Is it even possible? Thank you.
MacBook Pro, Mac OS X (10.7.5)
