Synopsis
This article describes an issue where end users may observe kernel panic Pulse Desktop Client crashing issues on macOS 9.0 and above with Pulse Desktop client version 9.0R1 - 9.0R3.1 installed.
Problem or Goal
Issue is applicable only if all conditions are met:
  • macOS 9.0 and above.
  • Running Pulse Desktop client is 9.0R1 - 9.0R3.1
This issue is not applicable to the following scenarios:
  • Any version of Pulse Desktop Client installed on any Windows operating system.
  • Installed Pulse Secure Desktop Client 5.3R7 and below on macOS operating system
Cause
This is due to the PulseSecureFirewall kernel extension (kext) module. 
Solution
Pulse Secure apologizes for the inconvenience caused.
 
The fix for customers who do not use Always-on, VPN only access, Lockdown mode or Traffic enforcement features will be available in Pulse Desktop Client 9.0R3.2 which is tentative for release by the 1st week of March, 2019.
 
The fix involves not loading the Kernel Extension (KEXT) by default when the Pulse Secure Desktop Client is installed.
 
For customer who do use Always-on, VPN only access, Lockdown mode or Traffic enforcement features are used, Pulse Secure is currently investigating further and will keep this KB updated when we have further updates.

Recommended Steps:
 
ScenarioShort TermLong Term
Customers not using Traffic Enforcement or Lock down modeOption 1: Run the unload kernel extension command:
 
sudo kextunload /Library/Extensions/PulseSecureFirewall.kext
 
Note: The unload command must be run after every reboot / restart of macOS as kernel extension is loaded by default during boot.
 
Option 2:
  1. Uninstall Pulse Desktop Client 9.0Rx
  2. Install Pulse Desktop Client 5.3R7 & below. Kernel extension is only supported starting with Pulse Desktop Client 9.0R1 to 9.0R3.1.
