Serato Scratch Live & Unibody MBP do not work with 4GB ram

Many people including myself are having problems with our new Macbook Pros and Serato Scratch Live. Models with 4gb of ram cannot play music on the usb device (or turntables) without distortion. The noise is to a point where Serato is unusable. When users pulled out a 2gb stick or ram, they report that the application and usb box work perfectly.

Rane is doing its best to work on the issue but the help of apple is needed. Thanks.
