Use Mac as a Hotspot to share internet? How to set up Internet Sharing and limitations you should know
Many people may not know that Macs can share their internet with other devices just like smartphones, using a feature called Internet Sharing, which can turn your Mac into a wired or wireless Hotspot. However, there are some limitations you should know before using it.
