Just talked with specialist at AppleCare. Explained that when I tried to create a slideshow from an album, the photos were put in random order, requiring the user to re-sort them in the tiny bar down below. Almost impossible and a huge waste of time. Specialist tried on his 2 computers with same result. He concluded it is a software problem with the new app. May be fixed in future, but who knows when.
Also discovered that if you try to make “quick” slideshow, you can only use one song, not multiple.

Any recommendations for third-party slideshow maker for Mac?

Create new album in Photos, >select all photos, >Photos>View>Sort>By oldest
Works for me every time. I didn't try "quick" slideshow.

Thanks everyone for your replies and suggestions.
The "sort" suggestion worked great until I realized that most of the photos had been scanned so had similar dates.
