I have a Macbook Air (model 2019) containing Thunderbolt 3 USB C, what should I buy as a cable connector to use my IMac 2009 as a monitor for my Macbook Air 2019?
There were at least five 2009 iMac models.

That iMac has a Mini DisplayPort and the MacBook Air has Thunderbolt 3 ports.
There are many sources for cables and adapters. Monoprice is one. I am unable to provide a specific recommendation only because I don't happen to have that model iMac (a 20 inch Mid 2009). Start with Monoprice and determine if you can find a recommendation from a reviewer.
Here's the Monoprice page: https://www.monoprice.com/product?p_id=24447
Reviews seem to indicate it'll work.
👍
Seems to be a lot of that same question recently. Using iMacs as displays for home schooling I surmise? Anyway check Amazon too, just don't buy one unless you find a reviewer who can confirm it will work with that model iMac. They're inexpensive enough and returnable but you don't want to waste time with one that doesn't work.
Exactly, it's for graduate school purposes.
I found this here, and i believe its the right fit.
One more thing to consider is an external display. Your MBA can support a 5K monitor which is astounding.
Of course that would be orders of magnitude more expensive than a cable, and the iMac's 20" display is much bigger than your MBA's, but it's not that impressive these days.
That's true, i was looking at it. but I will try to make it work with the cable for now.
My main concern was/is about the Thunderbolt 3 size. Because I know that for the new Macbook air I bought (2019-2020), they changed the size I believe.
What the rest of the world calls USB-C Apple calls Thunderbolt 3. It's actually more complicated because Thunderbolt devices require Apple proprietary Thunderbolt hardware.
I suppose Thunderbolt sounds less intimidating, but Apple's efforts to simplify things probably just added to the confusion. But in any event everything we knew as Mini DisplayPort is now Thunderbolt.
HDMI used to be simple too.
Apple iMac MC015LL is the model
Thanks for your help!
That's great. I think so too. I'm ordering it. Thanks for your help, John.
Use I mac 2009 as a monitor
