Is your iMac compatible?
Every Intel iMac from Late 2012 on works, 21.5-inch and 27-inch, Retina or not, and iMac Pro. Pick yours to see the cable you need.

Ethernet works with every iMac too. Your iMac needs macOS Catalina or later, which every model here can run.
Your Mac
Any MacBook Air, MacBook Pro, Mac mini, iMac, Mac Studio or Mac Pro on macOS 13 Ventura or later. Macs with Apple silicon can use any cable; Intel Macs use Thunderbolt or Ethernet.
Not supported
iMacs from 2011 and earlier (many have Target Display Mode), the 24-inch iMacs with Apple silicon (they use AirPlay), and Windows PCs (here's what works with a PC).
Which iMac is mine?
On the iMac, choose Apple menu › About This Mac. The name and year are under the macOS version, for example "iMac (Retina 5K, 27-inch, 2017)".
