WBC will continue to support older OS versions as long as Apple's developer tools make it possible to do so, and as long as we continue to have the ability to test those versions.
Currently most of our featured products are supported on Tiger (10.4), Leopard (10.5), Snow Leopard (10.6), and Lion (10.7), unless otherwise noted below or on the product page.
The days of the Tiger and Leopard are numbered. Since Snow Leopard, Tiger and Leopard have become increasingly difficult to support using Apple's Developer Tools. With Lion, this has become even more the case. While we will continue build our software for Tiger and Leopard, we no longer have a testing platform available. In other words, Tiger and Leopard support are theoretical.
If there is a another download button below the trial download button for a separate older version, mouse over it for details.
