Connect your Mac to the internet using Ethernet
You can use Ethernet to connect to the internet, either through an Ethernet network or through a DSL or cable modem. If you’re using a modem, make sure the modem is turned on and connected to the wall jack with the cable that came with the modem.
Use an Ethernet cable to connect your computer’s Ethernet port
to a modem or other network device (for example, a switch or a router). If your computer doesn’t have an Ethernet port, try using a USB to Ethernet adapter, or a Thunderbolt to Gigabit Ethernet adapter.In many cases, after you connect the cable, you’re automatically connected to the internet. If not, complete the following steps to enter your network settings. If you aren’t sure what to enter, check with your internet service provider (ISP) or network administrator.
On your Mac, choose Apple menu
in the sidebar. (You may need to scroll down.)On the right, click the Ethernet service
, then click Details.Note: If your Mac doesn’t have a built-in Ethernet port and you’re using an adapter, look for a service that contains the name of the adapter manufacturer or the type of adapter. For example, the service might be named [manufacturer name] USB-C LAN, or just contain the model number of the adapter.
If you want, turn Limit IP Address Tracking on or off.
Click TCP/IP in the sidebar, click the Configure IPv4 pop-up menu, then choose your ISP’s recommended configuration method.
Using DHCP: Choose this if you didn’t receive a specific IP address from your ISP.
Using DHCP with manual address: Choose this if you received a specific IP address and your ISP uses DHCP, then enter the IP address.
Manually: Choose this if you received a specific IP address, a subnet mask and a router address from your ISP, then enter those values.
If you received DNS server or search domain settings, click DNS in the sidebar, then enter the information you received.
If you received WINS (Windows Internet Name Service) settings, click WINS in the sidebar, then enter the information you received.
If you received proxy server settings, click Proxy in the sidebar, then enter the information you received.
