[OS X Emacs] Verifying Aquamacs

You forget that there are some 100,000 copies of Aquamacs sitting on
people's computers.  You can't remotely update which certificates are

The simpler solution (going forward) is to change the update URL going
forward to be something like update.aquamacs.org, and make the update check
via HTTP.

For now, I would first disable https on the server until you can figure out
how to make HTTPS not mandatory for all portions of the site.  Then, if it
can be done, you can exempt cgi-bin/currentversion.cgi from the redirect to
HTTPS, probably via an entry in .htaccess.
