For Mac OS X, the USB Base (QD125U) requires a firmware update before it can be made compatible. If not, please follow the instruction below to update the firmware on the base yourself.

The firmware update utility program works only on Windows 98/ME machine. Unfortunately for now, the update process is only PC-based. If you have no access to a Windows 98 machine, or if you don't want update the firmware yourself, please contact Tech Support and send back your unit and we will update it for you.

To update the firmware on the QD125U,

1. Download the v.2.6C updater package ("USB2IDE26C.zip") to a Windows 98/ME machine. Unzip the package using StuffIt Expander or WinZip.
2. Run the installer ("USB2IDE26C.exe") to install the updater to your PC.
3. Attach the QD125U USB Base to the USB Port of the PC. A caddy must be attached during the firmware update process, although the data in the caddy will not be altered in any way.
4. Run the updater utility program at "Start->Programs->scanlogic->usb2ide26c.bat".
5. Restart the PC.
6. Now try the QD125U on the Mac running Mac OS X.

For Mac OSX 10.2 users, in additional to the firmware update for the USB Base, you must also install the v.1.4 driver before the USB Base can be recognized.

All the files mentioned above can be downloaded from the table above.
