Can you install twitch on the laptop or can you only watch twitch in the browser?
You can also download Twitch.
https://www.twitch.tv/.../downloads
But BTTV and FFZ do not work there.
If you can install it, you have to go to Twitch, there's a download
It depends on which model
Also on the laptop: https://www.twitch.tv/.../downloads
For which operating systems? There are operating systems on which nothing can be installed and which do everything in the browser
And if you don't have windows or mac?
If he asks another question he will use Windows or mac. And both are available for download.
Yes also assume that windows is used. If he uses windows 10x or old windows like windows 95 or so he can't install it
If you have Linux you have this option: https://gnome-twitch.vinszent.com/
What if you don't have linux? There are also other large operating systems
Then next time simply write in your search which special NASA operating system you are using to which no one has access except.
There are large operating systems to which everyone has access, but which are not windows, mac or linix
