MACVAULT I'm currently running the trial of this, and have to say there seems to be some serious issues (with the Aperture version). I own Viveza from Nik as well and that plug in works great in both PS and Aperture, so I'm not sure what the issue is. I tried it on both a 2.33Ghz MBPro with 4MB of RAM as well as my 2.8 Ghz MacPro with 8MB of RAM and it's really slow. After uninstalling the Aperture version and installing the PS version, it runs just fine. Buyer beware.
