If your organisation set this Mac up for ORelay, there is nothing more to do: it will appear in your ORelay account shortly.
Click the ORelay icon in the menu bar, choose Open ORelay, and scan the code it shows with your phone (or open ORelay on your phone, choose Add a computer, then Scan). Once your phone has approved it, click Join. macOS asks for an administrator's password once.
For administrators: sudo /usr/local/bin/orelay-agent join shows the same code in
Terminal, or takes a code from Add a computer typed in.
To let someone see this screen, allow orelay-session-helper in
System Settings › Privacy & Security › Screen & System Audio Recording.
macOS asks for this once, from someone at this Mac.
An earlier version installed the agent under different names. This installer moved it to the new
ones, and the Mac keeps its place in your ORelay account. macOS ties its privacy permissions to a
program's name and place, though, so the ones given before do not carry over: allow
orelay-session-helper again under both Screen & System Audio Recording and
Accessibility. The old entries, called opsrelay-session-helper, no longer do anything
and can be removed there with the − button.
To remove the agent: sudo /usr/local/share/orelay/uninstall.sh. It asks what to
keep, and whatever it keeps, installing again picks up: the same settings, and the same computer in
your account. To remove everything, so the next install starts fresh, add --remove-all.
