Hi Aotino!
You can run Harpoon (and the vast majority of Windows' programs) on a Mac with an OSX system, but only using a Windows emulator - that is, a program that allows you to install Windows on your Mac and use your Mac like it were a normal Windows PC.
The one I use on my MacBook Pro laptop to run Windows 7 Professional is WMware Fusion 6 (
http://www.vmware.com/products/fusion/). It never gave me problems and it runs everything I run on my desktop PC.
There is another emulator called "Parallels" which is getting good reviews, but it gave me some headaches with War in the Pacific AE and Distant World graphics. Luckily I was still in my trial period, so I ditched it.
Be aware of three "Caveats":
- You must buy the emulator (about $60 for Fusion)
- You must have a valid copy of Windows to use specifically on your Mac: installing a copy already in use on another computer is illegal.
- The program runs OSX and Windows *at the same time*: you can literally switch from Mac to Windows in real time. However each OS will "appropriate" about half of the memory. If you have a 8GB RAM Mac you will basically run two virtual machines with 4GB each. There are workarounds in the option panels, but I only managed to crash the systems
Finally, you can use Apple's own "Boot Camp" (
https://www.apple.com/support/bootcamp/) - but I was discouraged from using it. It is complicated and painful to install. There is a reason as why you find so many third party products.
And that's it. Hope that the above helped!
