Unable to run or debug AIR apps on Mac using Flex 3.3
Ran into an issue today where when trying to upgrade and AIR project to Flex 3.3 I kept getting this error:

Luckily the fix is pretty simple. Download the fixlinks.sh script from the link. Copy it to your 3.3 SDK root, make it an executable and run it. You should now be able to run your AIR application with Flex 3.3.

I should notify u about this.
