Reprocess imported RAW files in Photos on Mac
If you import RAW files that were already processed by another app, the RAW processing of the photos might be out of date. The RAW processing used by Photos may also be updated when Apple releases a Digital Camera RAW Compatibility Update or an updated version of macOS. If you’re happy with how a RAW photo looks, you can leave it as is or you can reprocess the RAW file with the most recent version of Apple’s RAW processing software.
Important: Your photos may look different after reprocessing. You can’t undo this change.
Go to the Photos app
on your Mac.Double-click a photo to open it, then click the Edit button in the toolbar.
Choose Image > Reprocess RAW.
If the Reprocess RAW command appears dimmed in the menu, the photo’s RAW processing is up to date.
