I've done some googling, and I'm finding inconsistent advice. I'm sure this topic has been addressed here, but my searches are not coming up with what I want. Do you think Apple realized that when the replaced iPhotos with an application called, simply, "Photos", that they made it very difficult to search for information about the application? Googling (or searching anywhere) iPhoto turned up results for iPhoto. Googling "Photos" turns up results for photos -- not necessarily Apple's "Photos" application. I have what I think is a simple issue: On my old Macbook Pro (Late 2011, running el Capitan, 10.11.4), I have a Photos library (37.8 gb) and an iPhotos library (33.4 gb). I assume all of the iPhotos content was imported into and exists in the Photos library -- but is there a way I can confirm this? I would like to export my Photos library (assuming it is complete) onto a new Mac Mini that has no photos at all. What is the easiest way to do this? In Photos, I went to Albums, All Photos and then File-export-export folders. I got the following message: "Some of your photos and videos are stored outside of the Photos library. Photos needs permission to access this media. Please choose the folder named “15” at the path “/Users/DavidJStone/Pictures/iPhoto Library/Masters/2012/09/”." I'm not sure what this means? I can't navigate in Finder to a folder in the iPhoto library. When I try, it just opens the iPhoto app. I'm sure there is an easy way to do this. Sorry. and thanks in advance.
