Works on the following IOGear CAC reader models:
GSR202, GSR202V, & GSR203
- Update your system. (10.6.5 is the latest for Snow Leopard) Step 2: Plug in your CAC Reader to an available USB Port. Step 3: Click the Apple Icon in the upper left corner of your desktop and select 'About This Mac'.
- If you don't have a process named CAC, your card reader firmware may be out of date. You should update the firmware (using a PC works best). A lot of old SCR331 readers need a firmware update.
1. Information
Best SmartCard/CAC reader for a Mac? I have the Iogear card reader that is available at the PX. It was about $20 I believe and I had to download a couple drivers but it works just fine with my Mac. If you get this one there are step-by-step instructions on AKO on how to set the reader up.
Some IOGear CAC readers have a firmware version that will not work on a Mac (AU9540), this page will show you how to change it to AU9520, which will work on your Mac using a program called EepromMP.
2. This procedure must be completed using a Windows computer (or Bootcamped Mac), it will not work using a virtual version of Windows (i.e. Parallels, VMware, or Virtual Box)
2.1 Install the AU9540_V1.7.2.0 driver (from the CD in the box), then plug in the GSR202, GSR202V, or GSR203 to your Windows computer.You may also download it from: http://www.iogear.com/support/dm/driver/GSR202
2.2 Double click EepromMP.exe found at: http://militarycac.com/CACDrivers/iogear/AU9540_EEPROM.zipAU9540 reader will look like Figure 1. Click the Setting button (DO NOT insert your CAC in the reader).
