iMac Pro and Mac Pro come with a built-in 10Gb Nbase-T Ethernet port, and iMac (Retina 5K, 27-inch, 2020) and Mac mini (2018) offer 10Gb Ethernet as an optional configuration. This port supports 1Gb, 2.5Gb, 5Gb, and 10Gb Ethernet using RJ-45 connectors and standard twisted-pair copper cabling up to 100 meters (328 feet) in length.
When you connect your Mac to another device via Ethernet, the highest possible speed is negotiated automatically. The speed depends on the capabilities of the device and the Ethernet cable. For example, if the device that you connect to is 10 Gbps-capable — and the cable you use can support the speed — your Mac and the device can transfer data at 10 Gbps.

- When you use Windows via Boot Camp on your Mac, it's best to leave your Ethernet port speed set to Autosense. If you configure the link speed manually in the Network and Internet Control Panel within Windows, you might get Ethernet speeds that reach a maximum of 1 Gbps.
- If the data transfer speeds between your Mac and another device connected through Ethernet are lower than you expect, first make sure that you're using a supported cable type and length. Then check with the device's manufacturer to make sure its firmware is up to date.
