If you are, like me, not able to open certain websites in any browser on OS X 10.6 10.7 10.8 on a MAC with Hamachi LogMeIn installed…Fell free to uninstall Hamachi, because of it fails to setup the DNS Route correctly… Try to use another VPN Tunneling Tool or ask Hamachi for an update 😉
This problem occurred to me while browsing with Safari on ML 10.8.5 and 10.9. I reset Safari itself, delete the Keychain, tried every other Browser available, as it worked on every other device 🙁
(DO NOT DO THAT! JUST REMOVE HAMACHI!)
