Yes. The latest Liquid Mix installer is available for download here:
Please note: There are some current limitations with Liquid Mix on the Intel Mac. We are aware of a plugin redraw issue in Garageband 3. Steinberg Cubase 4 on Intel Mac does not support VST 2.3 plugins. If you would like to try a beta version of the VST 2.4 plugins for Liquid Mix please contact customer support here. Apple Logic, Digital Performer, Ableton Live, and Pro Tools LE are fully supported. Though the Intel Mac and PPC Mac installers are currently separate, we hope to deliver a public release of Liquid Mix in the form of a Universal Binary very soon.
