tethering

I just updated to 10.11.6 on my mac and now can't shoot tethered with my EOS 5D mark 1. Lightroom says it's compatible on its website, but this isn't the case. Does anyone know of a software program that is?

Hello everyone! Happy to be here where I share the same interest with others! I'm a begginer and I need some help - I want to create a studio. Basically, my plan is to get a camera where I can do "tethering", i believe this is what it's called, and take photos of me showing my make up. For now...
