Use a RAW file as the original in Photos on Mac
Some cameras allow you to shoot photos in both RAW and JPEG formats simultaneously. When you import photos from these cameras, Photos uses the JPEG file as the original—but you can tell it to use the RAW file as the original instead.
In the Photos app
on your Mac, double-click a photo to open it, click Edit in the toolbar, then choose Image > Use RAW as Original.
