USB Audio Driver V1.0.4 for Mac OS X 10.4-10.6 (Previous version)

Important Notice

About the USB audio driver

  • The USB Audio Driver is required to connect an IM8 or USB compliant MG Series mixing console to your computer.
  • When using the above products, even if the USB Audio Driver is not installed, a class compliant driver (OS standard driver) is automatically applied when the product is connected to the computer with a USB cable.
  • In some cases, depending on conditions or the specification of the computer, a drop-out noise in a recorded audio file can be produced as a result of an interruption in the signal flow. Usually setting the buffer size to a higher value can eliminate the problem however, if you encounter this issue when using the class compliant driver, and setting the buffer size to a higher value does not resolve the problem, please try the USB Audio Driver.
  • We also recommend you to use this driver when you want to try buffer size setting lower than a class compliant driver.

Caution

  • Apple has announced that the latest Macs will use a 64-bit kernel as the default OS setting. Due to the fact that Steinberg and Yamaha hasn't yet released 64-bit kernel drivers for Mac computers, you will not be able to install the following in these new Macs with their default settings.
  • Which Macs use the 64-bit kernel by default in Mac OS X v10.6
    * Also note that new Macs released in 2010 or later may use a 64-bit kernel by default as well.
  • If you are unable to install the latest driver (or Tools) to your Mac, please confirm your Mac model and the kernel mode. You can see which kernel you are using in System Profiler by following these steps:
    1. Choose About This Mac from the Apple menu.
    2. Click More Info.
    3. Select Software in the Contents pane.
    4. Look for "64-bit Kernel and Extensions: Yes (or No)" under the System Software Overview heading.
  • If your computer is using the 64-bit kernel, we recommend that you boot into 32-bit kernel mode by pushing and holding "3" and "2" on your computer's keyboard while re-booting your Mac. This is not a permanent setting and note that you will have to boot your Mac this way each time you want to run one of the drivers noted above.
  • Our development teams are working hard to offer 64-bit kernel drivers/extensions to our customers as soon as possible. Our website at steinberg.net will be updated with these drivers in the download areas as soon as they are ready.
