I’m posting this in hopes that someone, someday will Google it and have an answer for me in the comments. Because I don’t.
I’m trying to find an article that details how I can use my iMac as my primary machine, and my MacBook Air as the secondary display. Frankly, it’d be silly to go the other way because my iMac has much more power than the MacBook Air.
All of my machines use the Mini Display port. Haven’t found nary a thing online about the idea. Evidently, I’m the first to have it.
