Query: NOT FOR LEOPARD/SNOW LEOPARD USERS!

This is a fantastic piece of gear if you're running the following:1. Windows. Driver issues sound like they've been resolved. There are many bad reviews on the unit due to early problems here.2. Mac OSX Tiger.If you plan to run this on Leopard or Snow Leopard, be aware that there is an issue with the new Apple Firewire Audio driver that will cause you to get clicks and pops in your audio like crazy. These operating systems have been out for years, and there is still no fix from Mackie or from Apple. Both companies want to blame the other, and you know what that means- this is never going to get fixed. I bought one of these 9 months ago and have tried literally everything under the sun to fix the issues. I've rolled back the firewire driver to 2.01. Then to 1.2.2, which was the driver under Tiger OS 10.4. Nothing works, and I'm finally giving up and selling it to a Windows user.
