A notification shall appear of a new feature introduced with macOS 10.13 High Sierra. This feature enforces that only kernel extensions (KEXT) approved by the user will be loaded on a system. When a request is made to load an extension that the user has not yet approved, the load request is denied and macOS presents an alert.

1) Go to Security & Privacy option in Mac,
2) In the General Section, Click the Allow Button (for the message System Software from Developer "MicroWorld" was Blocked from loading)
3) Reboot the system
