When it comes to sharing an internet connection with a device that may not have access to the network your on, using your Mac as a Wi-Fi hotspot can really help you out. Much like tethering with your iPhone, Internet Sharing on macOS will allow you to share your Wi-Fi connection with devices around you, using your Mac as a proxy router. It's likely not going to be as fast as directly connecting to a Wi-Fi router, but it will help you get access to a network when you're in a tight spot!
How to share your Mac's internet connection
Before beginning, be aware that Internet Sharing works for any computer running OS X Lion (10.6) or later.
