Animation for Mac users

Hey everybody. I've being reading some post and there's a lot information for Windows user animators like Qavimator and BVHacker. I'd like to know if there's a fine tool to build animation over MacOs besides Poser.
Thanks in advance.

There are free MacOS versions of Avimator and QAvimator available for download. I'm not certain how "fine" they are compared to Poser. Definately worth a look if you are interested in creating some animations. I'd recommend saving your work frequently if you do give these a try- just incase they crash. They can sometimes be a little temperamental when loading a saved file ie. the application crashes.

Thank you Loco, I've just try the app and it seems to work just fine. Your reply has been very helpfull!
