Hi Stefan,

The Mac OS X version is in Beta, so we do not officially sell it yet.
If you are satisfied with the current version of Balancer for Mac OS
X, which has only several minor issues that do not affect the results,
you can go ahead and buy it here:

Of course, you will be able to get the final version as soon as it is
released, as well as all the future updates of Balancer 1.x.
