Copy

Screen: New box.

What it is

A small Copy button at the end of the check command in step 1 (shasum -a 256 and the file name). It copies the command.

Click it. Nothing to type.

For the dealer: The command is put on your clipboard and the button reads Copied for a moment. Paste it in your computer's terminal.

For the home: Nothing. It does not reach any home.

In the app: Nothing.

If the browser will not copy, Couldn't copy — select it and copy by hand shows and the command is left selected on the page: copy it with Ctrl+C (Cmd+C on a Mac). Copied only shows when the copy worked.
If the command shows — instead of a file name, the installer record has not loaded yet.
