Originally referred to as the "Leopard Installer" it was provided due to the installer on the original VDL 2.5 DVD becoming incompatible on Mac OS X 10.5 and greater. Instead, we recommend the 2.5.5 library update which will provide the fastest, most up-to-date version of the VDL library without having to download numerous other updates. If, for some reason, you still need access to the "Leopard Installer" for Mac OS X, instructions can be found here.
