We posted new installers to of H9 Control here:

The Mac version of H9 Control should work on OS 10.5. Let us know if you have any problems though…
Incidentally, it's getting harder and harder to support OS 10.5, because Apple keeps forcing us to upgrade to their latest development tools for iOS, which forces us to make other changes. We're going to support 10.5 as long as we can, but at some point that will become impossible.
