*Important Note:
*With the arrival of the macOS Big Sur 11.0& M1 chip, the operating system applies a stricter security policy to (any) software that requires kernel extensions aka kexts ("kexts" - think of it as a macOS version of "drivers"). The IVIIN driver installation includes a system extension that is affected by this policy. As a result, the user has to explicitly enable/allow this system extension within 'Security & Privacy' in system preferences (after installation and before the software is allowed to run)
