App Too Broadcast Mouse Clicks Across Multiple Windows For Mac

As the title says I'm looking for an app that broadcast mouse clicks across multiple windows. I can't seem to find anything that offers the ability. I need it to happen in realtime, I don't need it to record the mouse clicks. I've been searching for a while but haven't found anything. Sadly I'm on mac so I know it's hard to ever find anything like this. I already use clonekeys for the simple multiboxing setup I have but I'm looking to start gathering herbs and everything in WOW. Clonekeys doesn't fit the bill for it. So I need an app that can broadcast the mouse clicks accurately across multiple windows. I could go the route of bootcamp and running windows, or some other way of running windows on my mac, with Isboxer but I'm trying to avoid that if at all possible

As far as I'm aware, multiboxing software on OSX is dead (as in development or offerings), or is heavily outdated and works for only the most basic tasks. Most Mac users either dual-boot into Windows, or they figure something out with Parallels (or similar software).
