Hello Fréderic, sadly this has nothing to do with Flex nor AIR. Since OSX Mavericks, Apple introduced a feature called App Nap [1]. There's plenty of tutorials how to disable it from UI or terminal e.g. [2]. There's also Objective C API e.g. this stack overflow [3]. At the time we had to fix this problem it was not possible to do it directly from AIR, so we ended up building our selves an ANE. Unfortunately, we haven't open sourced it, so I cannot paste you the source we used. But it shouldn't be a problem with a bit of googling, it's also possible that someone also did such a thing and open sourced it and you'll be able to find it on github or elsewhere.
