PowerPhotos 1.3 is being released today with support for Apple’s latest version of macOS, High Sierra. If you’re upgrading to High Sierra, you will need to update in order to find duplicate photos, copying photos between libraries, or merge libraries together. The update also includes support for the new HEIF image format introduced in iOS 11, support for cloning libraries on APFS volumes, and a variety of other minor tweaks and bug fixes. This update is free for all existing PowerPhotos users and can be download either using the “Check For Updates” menu item within your existing version of PowerPhotos, or by downloading it from our website and installing manually. PowerPhotos 1.3 now requires macOS Sierra or higher, but PowerPhotos 1.2.3 will remain available for those who haven’t upgraded from El Capitan yet.
