Astro Gold Windows does everything on a Windows computer that Astro Gold for Mac does on a Mac computer. Because the apps were created as native apps for each platform, you cannot install Astro Gold Windows on macOS, nor the macOS app on Windows, but there is no need to do so. When you purchase Astro Gold for either macOS or Windows, you are given a dual platform license, which allows you to register either Astro Gold Windows on your Windows computer, or Astro Gold macOS on your Mac computer.
