new Photos app sharing library across users
How do I share one Photos (v 1.0) library with multiple users on one Mac? Currently, I have a 115 GB iPhoto (v 9.6.1) library that I share across users on one Mac. It's stored in the shared folder, and all family members have access. After installing the new Photos app and upgrading my library, I moved the new Photos app library into our shared folder, and changed permissions to allow read & write access for a second user, but it still will not open in that user's account. I must avoid duplicating the iPhoto library in each user account because I don't have enough disk space for 3 115GB libraries.
