There used to be no easy way to transfer files from your iPhone to your Mac unless you email yourself the file or otherwise connect your iPhone to your Mac.
As of recently, however, AirDrop supports connectivity from your Mac to your iPhone.
To enable AirDrop from your Mac to your iPhone simply follow these instructions.
- Click on Finder and click on AirDrop under Favorites
- Click on “Allow me to be discovered by: Everyone”
You must now do the same on your iPhone.
Now you should be able to select photos from the Photos app and share it via AirDrop by clicking the sharing icon.
Additionally, if you want to send photos from your Mac to your iPhone you can do it via AirDrop in Finder under Favorites.
