Set advanced Wi-Fi options on Mac
You can set advanced Wi-Fi-specific options. For example, you can specify preferred Wi-Fi networks and arrange them in order of preference. You can also specify whether an administrator password is required to control certain Wi-Fi capabilities, such as turning Wi-Fi on or off.
On your Mac, choose Apple menu > System Preferences, then click Network.
Select Wi-Fi in the list on the left.
If Wi-Fi isn’t in the list, click the Add button at the bottom of the list. Click the Interface pop-up menu, choose Wi-Fi, give the Wi-Fi service a name, then click Create.
Option-click Advanced, click Wi-Fi, then do any of the following:
Add a network to the network list: Click the Add button at the bottom of the Preferred Networks list, enter a network name, then choose a security type from the pop-up menu. To view available Wi-Fi networks, click Show Networks, then choose a wireless network from the list.
Remove a network from the network list: Select the network you want to remove, then click the Remove button at the bottom of the Preferred Networks list.
Prioritise networks: Drag the networks into the order you prefer.
Set options for networks: Select the tickboxes to the right of a network name to join it automatically, consider it a hidden network or allow the password for the network to be shared.
Automatically add networks you joined to the network list: Select “Remember networks this computer has joined”.
Require an administrator password to change options from the Wi-Fi status menu: Select any action under “Require administrator authorisation to”.
Click OK, then click Apply.
