What is a "ProToGo" USB SSD with tw

ProToGo is a thumb drive, or other device with a subset of MacOS and a selected set of bootable options. In my case there are two bootable options on the same thumb drive as I described.

I made the ProToGo and keep it current because I have several computers around here and I sometimes support friends and neighbors Macs when they have a problem. The ProToGo provides a handy way of doing that. NOTE: it has been at least three years since I needed to use an industrial strength volume repair utility like TechTool Pro so for all intents and purposes I keep the ProToGo out of habit — not necessity.

If we knew what it was we were doing, it wouldn't be called research, would it?
