WindowsDock is an application launcher with a Mac OS look to it.
OOn the first run, you can find the launcher at the top center. The first thing you'll notice is that in reality, it does not look at all like the Mac OS look you expected. Instead, you're going to need to spend some time in the settings to get that look. Once you add in applications, change some colors and transparencies you can get close to the Mac OS launcher, but certainly not an exact clone. Regardless, there's a ton of settings to configure your launcher anyway you like and is the programs strongest feature.
While we were disappointed that WindowsDock wasn't an exact Mac OS launcher replica, it's still very functional, small, and highly configurable.
