The photos I have taken on my iPhone for the two weeks are not showing up in Photos on my MacBook Pro. I checked Photo Stream. I keep my photos on an external drive which is not always connected connected to my laptop. An hour ago, I plugged the external into the MacBook Pro and loaded Photos. It brought up my main library. Nothing in Photo Stream since Sept 10. I have given it an hour now, and still nothing is coming into Photos. It shows Photo Stream with the dates from April till Sept 10. I am starting to worry that I may be losing many photos that don't come across. This laptop was new in April, so I assume that accounts for that start date. That full library on the external was being used by the old MacBook before that, until I set up the new laptop. I don't see where that should make any difference. Is there some big delay in Photo Stream working when the computer running Photos is not running the program with the Library attached?
