When you install the GlobalProtect app for the first time on a macOS device running macOS
Catalina 10.15.4, macOS Big Sur 11, or later or upgrade to GlobalProtect app 5.1.4,
you must enable the
system extensions that are used for
specific GlobalProtect features. If your administrator has configured split tunnel
on the
GlobalProtect gateway based on the
destination domain name and application process name or enforced GlobalProtect
connections for network access on the GlobalProtect portal (see
GlobalProtect App Customization), the
System Extension Blocked
notification message displays on the
GlobalProtect app during the installation. The message prompts users to enable and
allow the system extensions in macOS that are blocked from loading to use the split
tunnel and Enforce GlobalProtect for Network Access features.
