Mac Photos not sorting in chronological order

Have the photos been taken in a different time zone from where you imported them?

The date you are seeing in the Info does not show you, which timezone Photos has assigned to the date.

When Photos is importing the photos from a camera card, it will try to make an educated guess, which timezone belongs to the capture date. As far as I can tell, Photos will use the timezone of the GPS tag of the location of the photo, if the photo has GPS tags assigned. If the photo has no location Photos will use the timezone of your current location, when you import the photos.

Try the following: collect all photos from your camera, that are sorted incorrectly, in am album for easy access.

Then select one of the and use the command "Image > Adjust Date and time". This will show you a timezone strip and the closest city. Compare this to the timezone strip and closest city for one of your iPhone photos.

If the camera photos are having a different timezone, select all camera photos in the album with ⌘A, then open "Image > Adjust Date and time", click the time zone strip you want, set the correct "Closest city" in the time zone.

This will change, how the time is displayed. Now change the field "Adjusted" to the original time. Both "Origianl" and "Adjusted" should be the same.

I am never changing the timezone in my cameras, but are keeping the timezones set to UTC at all times, so I will always know, the camera timezone. This makes it easy to adjust the date and time for my Camera Photos.
