My friend, if you could find me an operating system that can do that, and then once inside the OS enable me to use every single function of the operating system like an able-bodied person in the way the Apple's does I'll give you a small prize.

I would absolutely love to use free and open source software for both my operating system and everything else, but only Apple provides an experience for people with profound disabilities that even comes close to the experience normal people have with their computers.

This reply might come across as snarky, but it isn't and I really have tried to find other operating systems that would allow me to do this. Not found any yet in a decade.

Sounds like you might have tried this already, but GNOME has had a history of working on accessibility, and I think they're quite open to bugs in case something is broken. How well it works in practice, I don't know, though:

Fedora or Debian is probably the easiest way to get a GNOME desktop these days.

Thanks, I tried persevering with gnome for quite a while because I wanted to use Linux day-to-day. But all of the accessibility stuff at the time was a subset of all of the things that ordinary user could do, that just wasn't enough when I started working and I needed something as full featured as Apple's offering.

I mean I'm obviously going to try and change the state of accessibility and Linux by submitting bug reports and getting involved, but it's a long slow process and in the meantime I need a computer that works.

Does Windows 10 let you use accessibility software on the login screen?

Yes. Most new Windows 10 devices such as a Surface Book or Surface Pro have facial recognition built-in. I haven't typed in a password in over a year.

Nope. And in my not so humble opinion and speaking from long and frustrating experience, using Windows accessibility software blows really really hard.

Really. Hard.

Narrator can run at the login screen too. https://support.microsoft.com/en-ca/help/17173/windows-10-he...
