Where can I find a Dragon City (on FB) free hack?

I'm looking for a free hack for Dragon City on Face Book, but I can't find a good one, that works on my Mac Book, because most of them are only for Windows. And there's a second problem, sometimes when I found a good download, I fist need to participate at something, like 'Win an Iphone!' or something like that. I don't want to do that. Can anyone please help me? Thanks x

Micro keylogger is recommended.It's much more multifunctional which is clean and undetectable as well. It even records typed passwords. Besides, you will find it's easy to use and be uninstalled. Their tech support is always helpful once you have any problem.
