What are the correct steps? I can make face detection works but finally I need to choose all and tag back that person for those photos. Is there easier way? Thx!

1. Run "Detect faces"
2. Select a bunch of pictures of the same person (Shift-click or drag a rectangle).
3. Hover over the "Who is this?" field and then type in their name. That name will be applied to all selected pictures.
4. Do this for a few bunches of pictures of each person. (So it has their names and an idea of what they look like)
5. Run "Recognize faces" and it should recognize other pictures of the people you have already tagged.
6. Go to the names that are bolded and go through the suggestions, rejecting any that are wrong by clicking the minus sign
7. Select all the suggestions that are correct (Shift-click or drag) and then click the checkmark on one of them to approve all suggestions.
8. Repeat from step 2 to tag more pictures of the same people that it didn't recognize.
