Connect monitors
How can i connect my iMac to my Macbook air? I need to use my iMac as a second monitor. I bought a USC type-c pub, but I think I am missing something. Thanks!
iMac 21.5″, OS X 10.11

that feature is being phased out.
The other Mac that you're connecting it to must have been introduced in 2019 or earlier and have macOS Catalina or earlier installed.
Use your iMac as a display with target display mode - Apple Support
