I'll bash it: MacTCP is awful. The first several versions of Open Transport with System 7.5.x were somehow even worse. And MacPPP was an abomination.

I like to show people Hunter Cressall's parody of the Switchers ad campaign to remind/educate them that the Macs of yore were no panacea. It's hilarious and spot-on. https://www.youtube.com/watch?v=rEvYETWVK6M
