With the release of the new 64 bit compatible drivers for Rane hardware included with Scratch Live 2.3, users running Mac OS X Snow Leopard 10.6.0 through 10.6.5 may find that Scratch Live will not detect that the Rane hardware is connected.

Workarounds

• Upgrade to the latest version of OS X Snow Leopard (10.6.8)
  
  OR
• Boot your computer into 64 bit mode by following these steps:
  NOTE: You will need to do this each time you boot your computer.
  
  1. Turn off your Mac.
  2. Power up your Mac.
  3. While your Mac is starting up press and hold the 6 and 4 keys at the same time. This will launch Mac OS X into 64 bit mode.
  
  There will be no noticeable performance differences using Scratch Live between 64-bit and 32-bit modes.
  NOTE: Some older Macs will not allow you to boot in 64 bit mode. In this case you should upgrade to 10.6.8.
