I have an iMac and a Macbook Air (both 2013) and I have a Thunderbolt cable to connect the two. I'd like to use the Macbook as an external monitor. When I connect the two, I don't see the "Arrangement tab" in the Displays tab under system preferences. Am I missing a step? Thank you!

This works to turn my iMac into the external monitor, but not the other way around (I want my macbook to be the 2nd monitor). I've tried cmd-f2 on the laptop but nothing happens. I've also tried the troubleshooting tips in that article.
Any tips? I appreciate the help!
See this on Target Display Mode.
Ahhh, missed that. You can't do what you want to do, the MacBook Air cannot be the target display.
Oh ok. Good to know. Thank you!
No Arrangement Tab for connecting external monitor
