Hello Adam - I've inherited a ST-2000XM from a previous professor and I'm trying to get it working with our telescope. The manual that comes with the camera indicates that I need Windows XP or earlier, but I see from this thread that people are using modern OSs with that camera. Do you know if a recent version of Mac OS would work with the 2000XM? I've downloaded the Universal Binary SBIG Driver Installer, but I'm still not able to link to the camera. Any ideas? Thanks, Seth
