Nothing except a standard installation of macOS/OS X is required.

We think this works in OS X 10.6 Snow Leopard and later.

We'd like to keep it working in as many versions as possible, but unfortunately, we just don't have test boxes running old versions of OS X adequate to make this happen. Development and testing mostly happens in the last 3-5 years' worth of macOS releases; as of 2020, this means macOS 10.12 and later.

But if you find a bug in an older version, go ahead and report it! We'll try to work with you to get it fixed.

If you're running OS X 10.5 or later, you're SOL. That's just too hard to deal with in 2020. ;)
