You can install Photopia on two computers with your subscription, regardless of the platform. That means you can have Photopia on a Windows Computer and a Mac using the same Registration Key at no extra charge!
The Mac version includes the same 21-day evaluation period as the Windows version. Photopia for Mac is also fully compatible with the Windows version, including the same high-quality royalty free Music Library and the same feature set. All of your Slideshows, slide styles, and transitions will work seamlessly on both platforms.
