Aug 21, 2016 Looks like I have a mail issue in the Sierra DP1. Wanting to see if anyone else has this manifest so I can trouble shoot or work out whats going wrong. I have IMAP with google apps and I store nothing locally on my Mac. Whenever I sent a mail it sends it and creates a new 'On My Mac' mailbox.
You can upgrade to macOS High Sierra from OS X Mountain Lion or later on any of the following Mac models. Your Mac also needs at least 2GB of memory and 14.3GB of available storage space.
Note that you can move your Photos Library and/or use option+click on opening to select a different library to flip through.Other native applications that work in the same or a similar way include iTunes (files stored in /Music/iTunes), Photo Booth ( /Photos/Photo Booth Library), iPhoto (RIP; /Photos/iPhoto Library), and iMovie ( /Movies/iMovie Library and /Movies/iMovie Theater). Change photo library on mac. What's Going OnThe reason that the Photos application is so small compared to the library is because the application only contains the files necessary to run the application - you can right-click and select 'Show Package Contents' to confirm this. The library, though, is stored externally, by default in /Pictures/Photos Library/, and all of your photos are stored there instead of in the app.I believe the reason the application works this way is so that you can store your files externally, saving space, while keeping the core application internally, where it doesn't take up much space but still runs more quickly than accessing an external drive.
