KM Old Build Compatibility?

I need to boot into an old OSX version to use an obsolete app to convert a bunch of inaccessible files. This process could benefit from automation. I've found the KM download archive; how can I find which version works with which OSX/MacOS?

How do I license an old verison?

Thanks!

Go to Stairways Software: Press Releases for the version and OS compatibility.

For licensing older versions, contact support@stairways.com.
