macOS High Sierra 10.13 Driver Installation Change

high sierra macos 10.13 driver kext kernel install blocked fail

macOS 10.13 has implemented an additional security layer for kernel extension drivers, such as the Line 6 audio drivers. After the Line 6 device is connected, the customer must open the Security Control Pane and accept the Line 6 driver in order for the device to be recognized.


Typically, you'll see this message when your driver gets blocked:

However, sometimes the driver gets blocked and the message won't appear. Your driver and hardware simply won't work. In either case, you'd need to approve the driver in System Preferences > Security & Privacy:
