This version includes additional guidance to ensure that the AnyConnect Kernel Extension (KEXT) is properly approved by the end user. This is a new requirement in High Sierra. 4.4MR4 and 4.5MR1 have also been tested for High Sierra compatibility, but will provide no further guidance to the end user (beyond the single OS prompt) that manual steps are required to provide full AnyConnect capabilities.
Additionally, with these older (compatible) AnyConnect releases, a reboot may be required after manually approving the AnyConnect extension to continue to run. This step is not required with 4.5MR2. Note: Customers using Host Scan must be running version 4.3.5038 or later of the module in order to detect the presence of the macOS 10.13 firewall.

This document briefly describes the possible error messages that appear during the installation of AnyConnect VPN client on Apple MAC machines and their corresponding resolutions. There are no specific requirements for this document.
The information in this document is based on these software and hardware versions: • Cisco ASA Security Appliance that runs software version 8.x • Cisco IOS ® Router that runs Cisco IOS Software Release 12.4(20)T • Cisco AnyConnect Client software version 2.x The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command. Refer to for more information on document conventions. This section shows a list of error messages along with the solutions. When AnyConnect 2.3 is launched from an Apple MAC machine, the Anyconnect Package corrupt or unavailable error message appears and eventually, the connection attempt fails.
This can be a problem with the absence of the MAC-related AnyConnect package on the flash of the router. Upload the suitable AnyConnect package for MAC in order to resolve this issue. Upload the corresponding AnyConnect package, which depends upon the MAC architecture.
For MACs on the Intel processor, you need the i386 macos image and for MACs that run the Power PC processor (PPC) you need the powerpc macos image. These are example packages for your reference: • anyconnect-macosx-i386-2.5.3055-k9.pkg • anyconnect-macosx-powerpc-2.5.3055-k9.pkg When split DNS is enabled on an AnyConnect setup, it is found that all the DNS queries are sent in clear but not tunneled. This is a problem with only the Apple MAC machines and works fine with Windows machines. This behavior is observed and filed in Cisco bug ID ( customers only). In order to resolve this issue, you can upgrade to the AnyConnect release 3.0.4235, which has the. As a workaround, you can also use the built-in IPSec VPN client supported by Apple, which does not have this issue.
The launch of AnyConnect from a Macbook Pro running OSX Leopard is not successful. The VPN gateway is ASA running 8.0.4.
The connection fails and the SVC Message: 16/ERROR: Initialization failure (mem allocfailed, etc.) error message appears. This can be a problem with the way the MAC machine attempts to connect to the ASA. First verify if any IPv6 adaptors are enabled on the MAC machine and check if MAC tries to contact ASA over the IPv6 network. If so, it fails as the IPv6 is not supported with AnyConnect. In order to resolve this, disable the IPv6 related services on the MAC machine and try to connect with an IPv4 address. There are intermittent issues with you launch the AnyConnect version 2.5 on the MAC with OSX 10.5.6.
The web-based installation was unsuccessful error message appears. At that time, you are unable to download and install AnyConnect, and the browser used is Firefox. If you reboot the MAC machine, this fixes the issue temporarily, but intermittently, the issue happens again. Verify if your VPN gateways are connected in Load-balancer mode. If it is connected, then there could be some DNS cache-related issues that cause improper DNS redirects.
In order to resolve this issue, always try to map the DNS URL to connect to one specific VPN gateway only. When you use the AnyConnect on a MAC machine, you can access the Internal Corporate network but you are unable to browse to the Internet.
