Environment
GlobalProtect Client
macOS 10.13 and later
Cause
According to Technical Note TN2459 from Apple, "macOS High Sierra 10.13 introduces a new feature that requires user approval before loading newly-installed third-party kernel extensions (KEXTs)." Additionally, Technical Note TN2459 from Apple indicates, "[t]his feature enforces that only kernel extensions approved by the user will be loaded on a system."
When a request is made to load a KEXT that the user has not yet approved, the load request is denied and macOS presents the alert with a System Extension Blocked message.
