You might have heard that Facebook announced Video Calling with the help of Skype on their service today. You might have also noticed that if you are running a pre-release version of Mac OS X Lion it simply does not work. In reality the Facebook video calling feature will work on Lion but is blocked due to the unofficial nature of Mac OS X Lion. Below are a few simple steps to get Facebook Video Calling working on any modern browser in Mac OS X Lion. We’re simply going to change your browsers user-agent to trick Facebook into thinking you are on a compatible OS.


Using the latest version of Safari on Lion simply enter system preferences and under the advanced tab enable the developer menu. Once clicked you will see a new menu option on the menu bar labeled “Develop”. Click on this and you can change the user-agent to something that will work with the Facebook Video Calling Service. I’ve tested Safari 5.1 (Mac), 5.0.1 (Mac), and Firefox 4.0.1 (Mac) and they all work properly. If you are confused reference the image below:

Google Chrome

Two options for Chrome exist firstly you can change the user-agent via a simple command in terminal. When Chrome is closed type the following in terminal.

open /Applications/Google   –args -user-agent=”Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_8; en-us) AppleWebKit/525.19 (KHTML, like Gecko) Version/3.2.1 Safari/525.19″

Or, you could download this plugin for Google Chrome that will allow you to switch the user-agent directly within the browser.


Similar to the second method for Chrome simply download this plugin and select the user-agent from the image below.

Once you have modified the user-agent you may also need to enable Facebook Video Calling for the first time. To do this simply navigate to and click get started. You’re all done. Enjoy the new features of Mac OS X Lion and Facebook Video Calling at the same time.

  • It’s not working with my Mac OS X Leopard. I tried the same steps described here for Lion, but it still doesn’t work. Any idea on how to get it working on Leopard?

  • Yes, I did all setup procedures and downloaded the “FacebookVideoCalling.jar” file, but when I try to run it all I get is a message saying: ‘The Java jar file “FacebookVideoCalling.jar” could not be launched’. My browser is a Safari 5.0.5 and I’m using a Mac OS X Leopard 10.5.8. 

  • does not work for me.. once i click the cam button it says i have to konfigure… done it 20 times, same happens …..people can call me but i cant answer….?? HELP

  • I’ve seen a few issues of my own. It might be a facebook issue. (The service is very new). As stated below you might need to try and update to the latest version of Java. If that does not help the best solution might just be to wait and see if facebook works out the kinks. 

  • I have done everything and video calling on Facebook does not work or even show on my page or friends. I can’t find an answer anywhere. When I go to the video calling page in f/b it says it will be available soon and to try back. Pleas help!!!
