Syncing and deleting photos
I’ve synced all of my photos from my iPhone and put them in iPhoto on my MacBook. If I go on my iPhone and delete all of the pictures I’ve imported will it also delete from my computer?
MacBook Pro 13″, macOS 10.13
If you actually imported the photos to the Mac using the cable, and you are not using iCloud Photos to move them to the Mac, you can safely delete them on the phone and they will not be deleted from the Mac.
