clippycoder

Happy to announce it successfully works on Monterey! I have just set it up (and am using it right now). You get an error because you cannot edit system extensions...

How far did you get in the installation? Did you allow the extension through system preferences?

@Jayiitb you can use easytether pro. It's very old, but still works even on M1. It cost $10 but it isn't throttled by my ISP.

Just saying, if you really need fullscreen support, you can just open chrome and download youtube as a webapp. That's almost exactly what this app does, and should support fullscreen.
