Moving away from the Apple eco system is taking me years. We still have that MacBook Pro, and there still are Photos libraries (remember iPhoto?) – mine is still about 100GB. I totally need to move albums in there into folders on the drive. When your over 40 years old you start to appreciate that the only way to archive pictures, audio and video is folders and files. All these tools that use databases and what not will eventually fade from your life. Don’t get locked in. Even if they’re free!
