I have two 27" iMacs that I would like to connect. I would like to use the older one as a second screen. I am having a hard time getting this to work.
Can someone help me figure out what cables I might need?
- On the older iMac - there is a display port, firewire, and USB 2 ports.
- On the new iMac - there are USB ports and Thunderbolt ports.
Can someone tell me what attachments or cables to buy to make this work?
