Hi everyone!
I just connected an iMac as a second monitor to my main iMac yesterday using a thunder bolt adapter and it worked just fine. I turned on my computer this morning and the second iMac is not recognized. I just don't want to set it up every time I start my computer.
I took the thunder bolt adapter out and inserted in again but that didn't work.
Your help is very much appreciated!
iMac, OS X Yosemite (10.10.1), null
If you want to turn off either or the computers you have to re-initiate Target Display Mode each time you turn the computers back on. Please look over Apple article about TDM located at Use your iMac as a display with Target Display Mode - Apple Support
Re-initiating is a minor nuisance, you have to type in Command + F2 on the computer that will be the external display and that sets it in motion.

I see. I just wanted to know if there's a way to keep it connected as a second monitor even if I turn off the computer, I understand now that it's not an option.
Thank you!
Your welcome.
