When Apple released Security Update 2015-002 (https://support.apple.com/en-us/HT204413) they included a fix for the “FREAK” exploit. Unfortunately, that fix broke the eppc protocol. Fortunately, they fixed it in a subsequent patch for Mavericks. Unfortunately, for Lion/Mountain Lion you have to download a separate patch at https://support.apple.com/en-us/HT201393. Fortunately, it’s an easy patch. Unfortunately, Apple never released a similar patch for Snow Leopard. Fortunately, somebody else did. Unfortunately, I can’t remember who. Fortunately, I still have it and you can get it here.
