Connection Question
I am looking to use my iMac 2020 as a second screen for my MacBook Air (2013) but not sure what cable I need to achieve this?
I understand that the MacBook is Thuderbolt 1/2 and the iMac Thunderbolt 3, but confused when looking on Amazon etc.
Any advice or help is much appreciated.
MacBook Air 11″, macOS 10.15
