Photos for Mac may not sync Faces over iCloud Photo Library, but it's still a useful way to organize and quickly find people in your images.
With Photos for OS X, changing the image that Faces uses for a person in the album screen has been tweaked slightly from its iPhoto days. Here's how to go about it.
How to change Faces key photos in Photos for OS X
- Open Photos for OS X and navigate to the Albums section, then select Faces.
- Select the Face whose photo you want to change and open the sub-album.
- Find the photo you want to use, and control-click (or right-click) on it, then select Make Key Photo.
