A Mac version is planned, yes.

Indeed, a mac version is planned.
A quote from the IndieGoGo page:

Originally posted by HoloTech Studio's:

We are starting on Windows PC, then iOS, Android, Mac and depending on our Technology partners also Linux.
We will not launch FaceRig for a new platform if we do not have enough funds and resources to finalize and properly support the previous one (out of respect for our user-base).
Of course we will hold community polls and if it turns out more people want Mac rather than Android for instance, we will switch the order.

I hope it picks mac support before Android... Mostly cause it most likally be less effort to get it to mac then android...

Also my PC broke, so i am stuck on a macbook.

Since they haven't even started on it yet, they probably can't give you an answer to it.
Just think that if you can run a webcam, run some kind of high-end modeling tool (photoshop for example) and can run a medium to high end game at the same time, your system will probably be able to run FaceRig, once it comes out. Probably the exact requirements will be less, but it can be a benchmark.

Windows Phone will be nice in the future :D

I have a Mac and would LOOOOOOOVE to use Facerig! Please make it your next priority!

I'd love to see a Mac Version, too. I would be able to entertain my viewers without showing my face and entertain other people like my little sisters and telling them fairy tales. That would be so awesome!

Like the linux thread, the mac thread will be locked too.
The devs are aware you all want it, and they will make it available when the time is right according to them.
