Note: Due to Mac’s limitation, you can’t be connected to a Wi-Fi network and host a Wi-Fi network at the same time.
The Mac’s built-in networking card can either connect to Wi-Fi OR host its own network, users can buy a Wi-Fi network adapter that should allow one network interface to receive the Wi-Fi connection while the other re-broadcasts it.
Alternatively, users can connect to the router using an Ethernet cable and share their VPN connection through Mac’s built-in Wi-Fi- networking card.
