How to view a photo marked up in iOS on my laptop ? (.AAE file)
iOS overlays the markup as saved in the .AAE file. Whenever you see the photo the markups will be overlaid.

Solution 1

When you send the photo to your MacBook Pro using AirDrop, a new image (the original image and the markup) will be generated on-the-fly and sent to your Mac with all markups intact.

For this to work you need a "MacBook Pro (Late 2008) or later, excluding the MacBook Pro (17-inch, Late 2008)". See Apple.com.

Solution 2

If you are not able to use AirDrop with your Mac, you may create a Shared Photo album with iOS' Photo.app. As soon as the shared image appears in the new album you can save it to your camera roll with all markups applied. Please note that the resolution of these photos will be reduced to fit 2048 px x 2048 px.

Solution 3

Use Photos.app on your Mac. If both the image file and the .AAE file are in the same folder they both get imported. You will see all markups applied in Photos.app.

To export an image with these markups applied just drag it to your Desktop or any other folder.
