Apple Users

I've done it. Matter of fact, had YellowDog Linux running on a powerbook G3 (the black one in Independence Day).
I feared no man for that sledgehammer of a laptop was with me.

You can download Knoppix DVD image or, these days, thumb drive image. Sometimes, it's in magazines, but I haven't bee hitting the magazine racks for a long time. It's Debian Linux and the point is, if it boots up from the "media" then it just runs. Optional to install it. Naturally, you partition the disk first if you don't want to trash whatever MacOS is there. procede with caution.

We (Sun and partners) were pretty high on "live CD" distros because you could deploy them in classrooms and the OS was unbreakable. Any hanky-panky, and you reboot to a clean OS. This is what Tails does, IIRC. Go into a hostile environment, and you know the OS is sparkling clean. I know that Knoppix runs on all the Apple intel hardware I've tried. Can't say for Tails.

I posted an article elsewhere about "being anonymous" in this age of anti-abortion bounties. I'll repost it for visibility.
I'm all the way up to HighSierra here. I was on cellular internet for years and years. I was not going to drag a 17 inch imac into the library, that's for damn sure. Will start upgrading now that I have this "best option available" DSL.

Good luck to all.
