iMac: How to connect M1 iMac to the network via ethernet cable?
M-series iMac Power Adapters and Ethernet
Power Adapter with Ethernet
The 24-inch M-series iMac comes with a 143W power adapter. If your iMac has four ports, the included power adapter has built-in Ethernet. The 24-inch iMac with two ports does not include ethernet by default. Ethernet is an add-on, and can be added at the time of purchase. The M-series iMacs are setup differently than previous iMacs, and no longer have an ethernet port located on the back of the computer.
Connect the Power Adapter
Pass the power cable through the hole in the stand and connect it to the power connector on the back of your iMac. Plug the separate power cord into the power adapter, then connect it to an electrical outlet.
Connect to Ethernet
Plug an Ethernet cable from your router or modem into the Gigabit Ethernet on the power adapter. The power adapter cable doubles as an Ethernet cable, so you don’t need a separate Ethernet cable from the power adapter to your iMac.
Power Adapter Missing Ethernet
If your M-series iMac power adapter does not include ethernet, you can use an USB-C ethernet adapter (dongle). ITS has multiport Anker adapters that include ethernet, and will work with your iMac. To order one, use the Multiport Ethernet Dongle request form.
