Please help me solve this problem! Photos I take on my iPhone 6 no longer are appearing in Photos on my MacBook Pro (new). I keep my photos on an external disc now and load that main system library from there when opening my Photos app on laptop. But for over a week, none of my new photos are showing up (as they are set to do in Settings). Each time I used to attach my external drive and load Photos, the Photo Stream would update. That no longer happens. Please help me learn what causes this and how I can fix it! Thanks.
