I was told by three different Apple support and sales people that a 27" iMac can be used as a secondary monitor by pressing cmd-f2. They were wrong, that has not been the case since 2014. Does anyone know of a 3rd party way to use a 27" iMac as a secondary display for a 1 year old MacBook Air? This is a big problem for me.
Thanks.
I am aware of that document. My question is whether there is a third party tool that I can use since Apple does not support what I need to do.
Not that I'm aware of. Perhaps someone else knows something different.
What specific iMac model do you have? How are you attempting to connect
it to your Macbook Air?
How is the iMac keyboard configured?
In Keyboard System Preferences, if the checkbox is enabled for Use all F1, F2, etc. keys as standard functions keys, the key combination changes to Command-Fn-F2.
It's an iMac 27", Late 2015 (I just picked it up yesterday). I have connected the MB Air via a thunderbolt cable and have tried CMD F2 and CMD-FN-F2 per systems preferences as you pointed out. I am pretty sure what I am trying to do is not supported by Apple which is why I am asking if there may be a 3 party solution.
Thanks,
There's no question it's not supported by Apple. For one thing it has a Skylake CPU which is the only Mac so far to use them.
