The OS X 10.8.2 update breaks compatibility with Qio, Qio CF4, and Qio E3 pro media readers, resulting in kernel panics on systems with Qio v1.1.6 and earlier software installed. By following the steps below, you may enable your system to work again, but the Qio will not operate after the procedure until you install Qio v1.1.8 or later software.
Process:
1. Cold-boot your computer holding the cmd and R keys together (this forces the computer to boot from the recovery partition)
2. Select the language
3. Open the Disk Utility application
- If your main operating system drive is locked (grayed out), select it and choose to “unlock” in the icon list at the top of the screen
- Note the name of the volume that holds your operating system - usually "Macintosh HD" – you will need this name later in these instructions
4. Quit Disk Utility
5. From the Utilities Menu, open the Terminal application.
6. Type the following commands, pressing the Enter key in between each command:
NOTE: In the following commands, <VOLNAME> is the name of the partition that your operating system resides on. This should have been obtained in step 3b. If your volume name has a space in it, such as "Macintosh HD", a “\” character must precede the space in the volume name (ie "Macintosh\ HD")
rm -r /Volumes/<VOLNAME>/System/Library/Extensions/STPCIFamily*
cp -rf /Volumes/<VOLNAME>/Library/Application\ Support/QIO/IOPCIFamily.kext /Volumes/<VOLNAME>/System/Library/Extensions
touch /Volumes/<VOLNAME>/System/Library/Extensions
7. Quit all applications and restart the computer.
