Connect to an 802.1X network on Mac
You can connect to a Wi-Fi or Ethernet network that is protected by the IEEE 802.1X standard. The 802.1X standard is designed to enhance the security of local area networks.
In most cases, your network administrator sends you a configuration profile that contains the information and settings you need to authenticate with the network.
When you download the profile from the web or open the attachment using Mail, the computer recognizes the .mobileconfig extension as a configuration profile and begins installing after you click Install.
During installation, you may need to enter passwords or other information that wasn’t specified in the profile.
On your Mac, choose Apple menu > System Preferences, then click Network.
Select the network service you want to use, such as Ethernet or Wi-Fi, in the list.
Click Connect. If you installed multiple profiles, click the 802.1X pop-up menu, choose the one you want to use, then click Connect.
If you are connecting to an Ethernet network that uses 802.1X and want to connect automatically to the network when it’s detected, click Advanced, click 802.1X, then select “Enable automatic connection.”
