This looks like a fragmentation issue, or MTU/firewall issue. Try
ike-frag=force, as the cisco you are talking to seems to support
FRAGMENTATION. If that fails, you can try to lower the mtu of your
interface a little.
This also can happen if the vpn service is not allowed to read the
certificate. The vpn service will stop to listen on udp/500 than.
Can you check the permissions of the certificate in the keychain
settings on your mac or check the log on mac site.
