IMO its easier to just run your chars on one PC for multiboxing and use ISboxer, it's practically free anyway and doesn't cost much. The problem of doing a mac and a pc together is you will be limited to the mac multiboxing options for the PC as well.
You can use MultiLaunchBox if you wish to stay on Mac. It well handle the launching, Screen resizing (barely), and key broadcasting. Just get the trial, it is a full unlocked version. Then if you like it and feel like donating go for it.

ISBoxer, however has a great deal more features, and way more support; from the creator and the community.
As the developer of MultiLanchBox, I use ISBoxer. Then again I stay pretty much on the PC these days.
