With enhancements implemented by Apple to provide better protections within MacOS X 10.13 and newer releases some software takes additional configuration to work correctly.
When the software is run the first time after installation the user may see a popup reporting that a system extension has been blocked. When this happens the user then has 30 minutes to open System Preferences, click on the Security and Privacy icon, and then click on the “Allow” button near the bottom of the window (see https://developer.apple.com/library/archive/technotes/tn2459/_index.html#//apple_ref/doc/uid/DTS40017658-CH1-TNTAG2 for more information). This should enable the GlobalProtect software (you may need to restart so the software can start correctly after being blocked by the system.)
If the user does not perform the above actions within 30 minutes of seeing the popup the approval button will disappear and the steps necessary to enable the software become more intricate.
Warning: These steps are for advanced technical users, if you are not comfortable working on the command line of your computer we recommend you see technical assistance either with your local desktop support representative or at a local Apple Genius Bar.
- Power your computer down
- Press the power button on your computer and immediately press the command and R buttons together (⌘-r) and hold until the Apple logo appears then let go and allow the computer to finish starting up (the process will be slower than normal).
- Once you are presented with the “macOS Utilities” screen select Utilities from the menu bar at the top of the screen and then Terminal
- Run the following command: spctl kext-consent add PXPZ95SK77
- Exit the terminal and then restart the computer
This should correct most issues related to the GlobalProtect client on MacOS X.
