How to identify Global Protect Driver issues on MAC Clients
After upgrading the Mac GlobalProtect client, the client never connects and just "spins".
- Click the Apple icon in the upper left hand corner, then click 'System Preferences', then 'Security'.
- Look for a message at the bottom of the window stating "System software from developer was blocked from loading."
- To allow the software to load again, click the Allow button.
If that doesn't work, try the following: Remove the GlobalProtect Enforcer Kernel Extension
Apple added extra layer of complexity in 10.13 and the linked article has all the explanations. OS X blocks signed extensions from loading. It doesn’t load unsigned extensions at all. This is the error message from the logs:
08/22/2018 10:13:17.062325[Error 183]: Failed to load KEXT pangpd_10.9.kext, error sys_libkern:sub_libkern_kext (0x37:0x2:0xd)
This approval UI is only present in the Security & Privacy preferences pane for 30 minutes after the alert. Until the user approves the KEXT, future load attempts will cause the approval UI to reappear but will not trigger another user alert. See this Apple page.
Once disabled try to enable the kernel extension for GP under System Preferences > Security & Privacy > General and then by clicking the Allow button. The user then needs to restart after clicking Allow to start the service.
- If the issue persist afterwards, another workaround can be tried. For this, the MAC would need to be booted into recovery
mode and then from Terminal issue the command
spctl kext-consent add PXPZ95SK77.
Boot into Recovery Mode. Instructions can be found here.
- Click on Utilities in the menu bar.
- Click on Terminal.
spctl kext-consent add PXPZ95SK77in the terminal note:
PXPZ95SK77is the unique identifier for Palo Alto Networks
Reboot the MAC system.
