PowerPhotos version 1.2 has been released, with support for macOS Sierra, which will be released by Apple on September 20th. In order to work with your photo libraries on Sierra, you will need to update to PowerPhotos 1.2, otherwise you will see an error message when trying to read the contents of a photo library. This is a free update, and can be downloaded either using the “Check For Updates” menu item within your existing copy of PowerPhotos, or by downloading from our website at https://www.fatcatsoftware.com/powerphotos. The update also contains a handful of bug fixes, and one new feature, which lets you choose a custom shade of grey as the background color for the main photo browser, instead of the default white background. Enjoy!
