How to move or export all Photos' library contents to a hierarchical by-date filesystem structure?
Photos Takeout app can export Year-wise, Album-wise and Date-wise folders from Photos for Big Sur, Catalina, Mojave and High Sierra, for libraries of up to 2 terabytes in size, while preserving folder hierarchy and metadata. It's not meant for iPhoto. [Disclosure: I do customer service at AIL, developer of this app.]
