Share the internet connection on Mac with other network users
You can share the internet connection on your Mac with other computers on your local network. For example, if your Mac is connected to the internet using Ethernet, you can share that connection to other computers over Wi-Fi.
On your Mac, choose Apple menu > System Settings, click General in the sidebar, then click Sharing on the right. (You may need to scroll down.)
Click the Info button next to Internet Sharing.
Click the “Share your connection from” pop-up menu, then choose the internet connection you want to share. For example, if you’re connected to the internet over Ethernet, choose Ethernet.
In the “To computers using” list, select the port other computers use to access the shared internet connection. For example, if you want to share your internet connection over Wi-Fi, select Wi-Fi.
If you chose Wi-Fi in the “To computers using” list, click Wi-Fi Options, configure the internet-sharing network, then click OK.
Network Name: Type a name for the shared connection.
Channel: Click the Channel pop-up menu, then choose another channel if you don’t want to use the default channel.
Security: If available, click the Security pop-up menu, then choose an option.
Choose WPA3 Personal if all computers that use the shared connection support WPA3.
Choose WPA2/WPA3 Personal if some computers that use the shared connection support only WPA2.
Password: Enter a password. If you want to see the current password, select the “Show password” checkbox below the password.
Turn on Internet Sharing.
If you’re sure you want to turn on internet sharing, click Start. Otherwise, click Cancel.
WARNING: If your internet connection and your local network use the same port (Ethernet, for example), investigate possible side effects before you turn on internet sharing. In some cases, sharing your internet connection disrupts the network. If you use a cable modem, for example, you might unintentionally affect the network settings of other ISP customers, and your ISP might terminate your service.
