Back in the day, before my iPhone or iPad was usable as a hotspot, I used to use my Mac as a hotspot. I’d plug it into, say, a hotel’s ethernet cable, then open up my WiFi for the folks around me.

I haven’t done this in years, since my iPhone hotspot works pretty well and since WiFi is so easily found. That said, in general, the performance you’ll get from an ethernet plugged-in hotspot is much better than you’ll get from your sometimes spotty cellular service.

Nice walkthrough from Jonny Evans. Tuck this one away and pass it along.
