Can I use my iMac 2012 High Sierra as a monitor for my Macbook pro, macOS Sonoma 2019?
I would like to connect them with Apple MMEL2ZM/A Thunderbolt 3 (USB-C) to Thunderbolt and I want to be sure that it's doable before paying for the "cable plug".
That 2012 iMac would have a resolution of 1920x1080 if it is a 21.5” model, or 2560x1440 if it is a 27” model.
Given how the prices of monitors have fallen over the years, I’m not sure that it is worth putting money into something like Luna Display (Astropad) or Duet Display (a “subscription” / rental application) that could have gone towards the purchase of a decent monitor.
You read the Support document correctly. Apple made it so that newer Macs and versions of macOS do not support using any iMac as a Target Display.
Basically, taking away a feature, rather than adding one.
I found out that 'the other Mac' that you're connecting it to must have been introduced in 2019 or earlier and have macOS Catalina or earlier installed. But it doesn't make sense does it?
Thanks for the answer.
Can you recommend the next best solution on how to use my iMac as monitor for my Macbook pro?
