Update alert delegate? SUUpdateAlertDelegate

[aonez]

I'm just looking for a way to know if the Update Alert has splashed and the result of that alert so I can quit the host application only if this alert is not shown. I'm seeing the protocol SUUpdateAlertDelegate but seems it's not in use. There's any API for that? Should it be done?

If the install button is pressed all download/installation methods in SPUUpdaterDelegate are called after the alert has closed, so I can't safely determine if the update started before detecting the alert closed.

Thanks in advance!
