Cisco Anyconnect Mac 10.15

Posted onby
10.15

Initially the laptop was installed with Yosemite with Anyconnect 4.7. It was then upgraded to Catalina and the client would not work. We upgraded the client to 4.8, and it still did not work. A factory re-install was performed back to Yosemite and freshly upgraded to Catalina and a fresh install of AnyConnect 4.8 and this did not work, except.

  1. Apple will be addressing these issues in future releases of macOS 11 but will not be fixing these issues in macOS 10.15. Consequently, starting with version 1.14.1, the Mac Connector will use legacy kernel extensions instead of system extensions on all versions of macOS 10.15. Mac Connector 1.14 is required to ensure endpoint protection on.
  2. .To use AnyConnect with Mac OS 10.13 (High Sierra), you must follow a manual process to leverage Cisco AnyConnect’s complete capabilities.

Defect Information

Defect IDHeadline
CSCvq59308MAC 10.15 : Hostscan 4.8 is failing with error ' Posture Assessment Failed '
CSCvq1181332 bit hostscan causes 'This application is not optimized for your Mac ' error with anyconnect 4.7

Problem Description

When used with macOS Catalina 10.15.x, VPN connections will not be established with some versions of Cisco AnyConnect Secure Mobility Client and some versions of the HostScan package.

Install Cisco Anyconnect On Mac

Background

HostScan provides the AnyConnect Client the ability to identify the operating system, anti-virus, anti-spyware, and firewall software installed on the host.

Cisco Anyconnect Windows 10 Download

In macOS Catalina 10.15.x and later, the operating system will no longer support execution of 32-bit binaries, which are included in HostScan packages 4.3.x and earlier. As a result, AnyConnect Client end-users who attempt to connect from macOS Catalina to a Cisco Adaptive Security Appliance (ASA) head-end that runs HostScan package 4.3.x and earlier will not be able to successfully establish VPN connections. Cisco AnyConnect 4.8.00175 is the first version that officially supports operation on macOS Catalina and contains no 32-bit code.

Problem Symptom

If a device that runs the macOS Catalina release attempts to connect with an ASA head-end that runs HostScan package 4.3.x and earlier, this “Posture Assessment Failed: Hostscan CSD prelogin verification failed” pop-up warning message appears:

Additionally, during the first launch of AnyConnect HostScan, SystemScan, and DART modules on macOS Catalina 10.15.x, one-time-only file access request pop-up messages might appear. For further information, refer to the AnyConnect Client 4.8 Release Notes.

Workaround/Solution

Solution

For macOS Catalina 10.15.x users to successfully establish VPN connections using AnyConnect Client with HostScan, these three steps must be performed:

  1. HostScan package on the ASA head-end must be migrated to HostScan 4.8.00175 or later.
  2. If you migrate from HostScan 4.3.x to 4.8.00175 or later, the Dynamic Access Policy (DAP) policies must be updated to the new DAP policy definitions introduced in 4.6.x. For additional information, refer to the AnyConnect HostScan Migration 4.3.x to 4.6.x and Later document.
  3. AnyConnect Client must be upgraded to 4.8.x or later.

Workaround

If an upgrade to HostScan package 4.8.00175 or later is not an option, administrators of systems with HostScan package 4.3.x and earlier can disable HostScan on their ASA head-end in order to restore VPN connectivity. If disabled, all HostScan posture functionality and dynamic access policies (DAPs) that depend on endpoint information will be unavailable.
