That is a great question! You can use VirtualBench on Mac OSX. However, to do so, you have to use Windows in a virtual machine like parallels.
Many users have requested direct Mac OSX support without having to use Windows in a virtual machine, and this is definitely a feature we hope to be able to add in the future! While there is no set time frame for this feature, I anticipate we will prioritize other features such as bus decoding in the Windows application and flushing out iOS app features for the time being.
Thanks for letting us know you want Mac OSX support, and let us know if there are any other features you would like to see in VirtualBench!
