How do I uninstall the US224/US428 driver in OS X?
The file (US224_OSX_3_21.sit) is a self-extracting archive, which means that Stuffit will
automatically expand the file once it is finished downloading it. Once unStuffed, OSX’s Disk Copy
application will mount the disk image on the desktop and open the folder.
Before installing the 3.2.1 drivers, remove any older version, if one is present.
To remove an older version:
1. Double-click on the ‘US-224 Remover’ icon.
2. If necessary enter your Name and/or Password in the ‘Authenticate’ window to allow software changes under Mac OS10.x and then click ‘OK’.
3. You should now see the ‘Welcome to the US-224 Software Remove Installer’. Turn OFF your US-224 and then click ‘Continue’ to advance to the next window.
4. ‘Select a destination disk’ – refers to the disk from which you want the files removed. Select the appropriate disk and click ‘Continue’.
5. ‘Easy Install’ – click ‘Upgrade’. A warning will appear reminding you that you will have to restart your computer at the end of this process. Acknowledge by either clicking ‘Continue Installation’ or pressing ‘Return’. If you do not wish to continue you may click ‘Cancel’ at this point.
6. After the software has been successfully removed (it will say ‘Installed’) click ‘Restart’ to
complete the process. Once your computer has restarted you will be ready to install the new version 3.2.1 driver software.
