Hi Jake,
It's now deteced the OSX install enry on the boot menu and passed the keyboard detection in the installation process.
However, when it come to the os recovery / os installation / disk utility dialog, and I choose the "disk utility" to partition my SDD with a partition name, I found it's not response to keyboard inputs.
What's the problem, is may keyboard not compatible with the PS2 ext, or any thing wrong with the ACPI / config.plist ?
Thanks very much!
Kevin
