Relinking your Photos Library.

My computer doesn’t seem to be able to access the photo library for some reason
___________


To have the Photos app relocate your photo library, try holding down the Option key while launching Photos. This will present you with a list of candidates. Select the preferred library and that should reopen the missing pictures. It is possible to have more than one library. This is sometimes done by accident so you might have an empty library and a full one. The correct place for a photo library to live is in the User's pictures folder. Some people move their photos library over to an external drive due to space concerns.
