Updater not working?

The “Check for Updates” option on Mac doesn’t seem to work. Is this intentional because it’s beta? If so, how should I check/get updates?

The only way I found is to redownload and then I have to signup again (and get all the emails again).

Can you define “doesn’t seem to work” more precisely? it should work (and does for me).

Sent PM with screencast of the problem
