Changes to macOS Security Policy With Silicon processor computers running macOS Big Sur or greater, Apple has changed their security policy. These machines no longer allow third party drivers to be installed in the manner that they previously had. Driver installs now require the macOS security settings to be lowered before installation. As Silicon is still new to everyone, we expect to see bug fixes, changes and optimizations to macOS Big Sur and possibly subsequent macOS releases over the coming months. With that, the Silicon driver install process may change as well. As such, we encourage you to update your Silicon machine to the latest Big Sur version, which is currently 11.6, before installing drivers.

macOS 10.13/10.14/10.15/11.4 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.
