macOS High Sierra 10.13 introduced a new security feature that requires manual user approval before loading new third-party kernel extensions.

User Approved Kernel Extension Loading

To improve security on the Mac, kernel extensions installed with or after the installation of macOS High Sierra require user consent in order to load. This is known as User Approved Kernel Extension Loading. Any user can approve a kernel extension, even if they don’t have administrator privileges.

A walk-through of the user approval process

When a user installs an application on a Mac (either from a local source or via Managed Software Center) which loads a third-party extension, the load request is denied and macOS presents the alert shown in Figure 1.

• Box Drive (cloud storage and collaboration application)

• Cisco System's AMP for Endpoints Connector (antivirus and malware protection)

• Palo Alto Networks GlobalProtect (VPN client)

• VMWare Fusion (virtual machine application)
