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. Some products may also work on Panther, but Panther is no longer supported for any product.
The days of the Tiger are also numbered. Since Snow Leopard, Tiger has 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, we no longer have a testing platform available. In other words, Tiger support is theoretical.
If there is a third download button below the Main & Trial downloads for a separate older version, mouse over it for details.
Otherwise, use these download links:
The last Panther-compatible version of iDupe is
version 2.5.3.
(Those on Tiger or Leopard may find version 2.5.3 to be quite stable also.)
The last Tiger-compatible version of CaliBrate is
version 1.5.
The last Tiger and DEVONThink Pro 1.x compatible version of DevonSync is
version 1.2.4.
The last Panther compatible version of Cast Away is
