Apple’s Photos app isn’t a walled garden. You can import images and videos into the app and export them back out, both in their original form and with any modification you made or as a transformed objected into a different format or resolution. However, what you can’t do is exports albums with a simple click.
You’d think this would be relatively straightforward, because the album is the unit of storage in Photos for macOS and other Apple platforms. There are albums you assemble as manual collections of media and smart albums that gather their contents dynamically based on criteria you sent. And yet, while you can choose albums in Photos by clicking the My Albums link in the sidebar and then selecting one or more albums, you cannot export them and retain album organization.
