Yes, there is a version of SopCast for Mac OS X and it can be downloaded from the official website.
The latest version is 1.6.4 and it's compatible with Yosemite, that means you can install it on Mac OS X 10.6 and up.
If you have problems with the latest version, pick the previous one. It might not have compatibility with Yosemite, but it will work without bugs.
