iMac 2012 as external monitor in MacBook 2020

Use your iMac as a display with target display mode - Apple Support

Read the article carefully, including the small print. There is some confusion on wether or not 2020 Macs will still support target display mode or not.

From the article I posted;

• All iMac models introduced in 2011, 2012, 2013, and mid 2014: Use a Thunderbolt cable to connect your iMac to a Thunderbolt or Thunderbolt 2 port on the other Mac. If the other Mac uses Thunderbolt 3, you can use the Apple Thunderbolt 3 (USB-C) to Thunderbolt 2 Adapter with your cable.

"You can connect any of these older iMac models to another Mac from 2019 or earlier for use as an external display.
