I don't know, but it seems like a fun thing to try out.
How did you set this up? Could you provide a few details?
Is there something similar in fish shell?
Wait is that email service the one that is offer by the same guys, who also offer 420blaze.it, cocaine.ninja and cock.li?
The easiest solution is to go to Settings -> Instance and toggle both "Disable Piped proxy" and "Local stream extractions"
Wait so Cloudflare actually isn't the bad guy for once?
If you host your own private instance, it's less likely to get blocked. But quite a few public instance are having trouble right now.
Grayjay is source-available, but not free & open-source software.
Downloading YouTube videos works, but it's probably not the desired workflow for most people. It takes up storage space on your disk, and you have to wait for the video to download, before you can watch it. I like Tube Archivist, and use it myself for archiving videos, but I wouldn't consider it a great solution for just watching videos. I think LibreTube, FreeTube or a self-hosted Invidious instance are better solutions here.
You can easily deploy Invidious on that Mac as well. Just use Docker, Invidious has pretty good documentation for that: https://docs.invidious.io/installation/#docker-compose-method-production
I used to host Invidious like that on a Mac for almost a year, it worked flawlessly
Some instances like inv.nadeko.net still work pretty well
You can also host your own instance at home on a small server or a VPS. You can optionally put it behind a VPN using Gluetun.
In my opinion Revolution is the best one
