Handbrake is compatible with Mac OS (10.6-10.10). You can use it as usual. Anyway, if you want to try something different, Any video converter, MacX video converter, Miro video converter would be nice choices. I tried all of them on my MacBook Pro, all works well.
I got that wrong, oopsIt sounds like OP is looking for a Kirara replacement on OS X, and Handbrake isn't it. He wants Handbrake+ or something.
