Apple tot up an cyberspace share-out selection in the Sharing system preference many class ago . This feature of speech allow you share one Mac ’s incoming internet connection via other web interfaces on that Mac . At one peak , this was a popular way to make what was once called a “ software bag station ” and now is more generally called a “ personal hotspot . ”
But it ’s also a great way to bridge your meshing if you have an older Mac with either broken , lose , failing , or light Wi - Fi . As Apple has mature its line - up of data processor , it has also upgraded the flavour of Wi - Fi supported . Macs onetime than five or so long time include slower , elderly edition of Wi - Fi and electronic internet cards that have weaker signal transmission and reception as well as radio with less tolerance in sorting out overlapping signals .
Ethernet and Internet Sharing offer one way to fix that if you have an easy enough room to connect two desktop Macs with ethernet ports . ( you could link up laptops , too , but then this solution works only when the sharing Mac is present . ) If either Mac miss ethernet , you could tally it through a USB - ascorbic acid or Thunderbolt 3 wharf for newer Macs or a USB adapter or Thunderbolt 2 adapter or dock for older Macs .
This share-out organisation bring forth an IP address for the Mac with which its connection is shared , and deal relaying data to and from the internet for that other Mac . It also allows a direct full ethernet focal ratio connection between the two Macs connected in this manner .
