Hi
I currently have a 2020 model MacBook Pro and wanted to use my late 2012 27” iMac as a second monitor. Firstly trying to find out if it’s possible, whether they’re compatible and secondly where I source an adapter since I only have USB ports on the back of the iMac (which doesn’t help me much). Can anyone help?
In theory, it will not be possible to use Target Display Mode with this iMac or your MacBook Pro
Late 2014 & later iMac models do NOT support Target Display Mode. The other Mac that you're connecting it to must have been introduced in 2019 or earlier and have macOS Catalina or earlier installed.

I couldn't agree more. Maybe something you may want to tell Apple directly? If so, try this link: Product Feedback - Apple

Sorry, you cannot. 2020 Macs are not compatible with Target Display Mode.
