I'm trying to connect my Macbook Air 2017 to iMac 2013 so I can use the iMac as my dual screen. My Macbook Air has a Thunderbolt 2, so I bought a Thunderbold 3 (USB-C) to Thunderbolt 2 Adapter and connected that to the Thunderbolt cable to the iMac - I pressed the Command + F2 on the iMac and still nothing happened.

• The source Mac must have been introduced in 2019 or earlier and have macOS Catalina or earlier installed.

Sorry, that won't work. Your iMac isn't compatible with Target Display Mode.
