How do you set up CS5.5 to publish to Flash 11 player on OS X?

Take a look here http://www.adobe.com/support/flashplayer/downloads.html?PID=4172469#fp11

On Windows I have, just change to reflect the locations OS X, sorry I don't have my mac with me today :/ . If you get stuck let me know. Reload Flash Pro and you should then have the option for FP11 in the publish properties.
