I recently hit a problem on my MacBook Air when trying to use Cisco WebEx. The Mac is running OS X 10.11 El Capitan.

The WebEx client installed without an issue, but when I tried to join a meeting the connection would hang at 98%. I had to use Force Quit to kill the client.

The solution to the problem was to change the proxy settings in Network Preferences. I’m not using a proxy but WebEx seems to have difficulties with the default setting.

Open “System Preferences” then select the “Network” icon.

Now select your current network connection from the left-hand panel (in my case this was Wi-Fi). Click the “Advanced…” button on the lower right of the panel.

Click the “Proxies” tab and the proxy settings are on the left. I’m not using a proxy but the default setting is “Auto Proxy Discovery”. Untick that, click “OK” and then “Apply” and WebEx would connect without any further problem.

Cisco has released free software updates that address the vulnerability described in this advisory. Customers may only install and expect support for software versions and feature sets for which they have purchased a license. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license:
https://www.cisco.com/c/en/us/products/end-user-license-agreement.html

Additionally, customers may only download software for which they have a valid license, procured from Cisco directly, or through a Cisco authorized reseller or partner. In most cases this will be a maintenance upgrade to software that was previously purchased. Free security software updates do not entitle customers to a new software license, additional software feature sets, or major revision upgrades.

Mac OS X (for Intel Mac) Setup Although WebEx Training Center will automatically be set up when you host/join a meeting, you can save time by setting up WebEx Training Center, on Windows or Mac, before the meeting. Sep 18, 2015  Go to Apple menu -> About This Mac to find your Mac OS X version. IOS does not run on Macs, it only runs on iPads, iPhones, and iPod Touch. I've successfully used WebEx meetings as recently as having Mac OS X 10.9 installed last June.

When considering software upgrades, customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories and Alerts page, to determine exposure and a complete upgrade solution.

In all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.

Customers Without Service Contracts

Customers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should obtain upgrades by contacting the Cisco TAC:

Webex And Mac Users

Customers should have the product serial number available and be prepared to provide the URL of this advisory as evidence of entitlement to a free upgrade.
