Can I use an early 2009 iMac as a display for my new Macbook Pro?
I have a new Macbook Pro and an early 2009 iMac. I also bought an MDP to MDP cable. Unfortunately I am unable to activate the iMac work as a display for my new Macbook Pro. I press the Command + F2 keys without much success. Anything I should be doing different? Any help would be ver much appreciated.
Thanks
