How to identify Palo Alto GlobalProtect Driver issues on MAC Clients
After upgrading the Mac GlobalProtect client, the client never connects and just "spins".
If that doesn't work, try the following: Remove the GlobalProtect Enforcer Kernel Extension
This issue could be related to a security setting for the Mac Keychain. Properly restart the computer by clicking restart, and making sure the "Reopen windows when logging back in" is unchecked as shown here:
Once the computer restarts and GlobalProtect restarts upon booting back up, there will eventually be a prompt that pops up. It will ask for permission for GlobalProtect to use confidential information from the Keychain. For example:
The password should be the computer's Admin password, or their Apple ID password. Once the password has been entered, click "Always allow". Afterward, GlobalProtect should be able to move past the "Connecting" phase and will prompt for username and password as usual.
However, if the previous troubleshooting did not work, the issue could persist because Apple added an extra layer of complexity in 10.13. 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.
spctl kext-consent add PXPZ95SK77.
