I was looking forward to installing this theme on my Mac and showing off its Leopard-like feel. Unfortunately, it felt more like a disappointment.
While you'll get the sleek semi-transparent menu bar, and the new Dock look, this last one feels a bit buggy and looks odd to me. Installing it is a bit of mess too.
You'll have to check access for assistive devices from Universal Access in System Preferences. Running the installer for Liger won't be enough to set it up though, as you'll also need to add themes, icon set and pictures.
Still, this is a great effort and a nice way to get Leopard on your Mac before anyone else. If you can't wait for the release of Apple's next operating system, it's well worth the pain of installing Liger onto your Mac.
