A macOS image capture bug was discovered April 22 which can fill your hard drive with empty data.
Image capture bug
When you connect an iPad or iPhone to your Mac and use Image Capture to transfer the photos you’ve taken to the Mac, you’ll see an option to convert these images to Apple’s HEIC file format. You can do this by unchecking the Keep originals box.
The images will be converted but this will also add 1.5 MB of empty data to each photo. By “empty” it means that when examined with a hex editor many lines of zeros will be added at the end of the file, as shown in the image below.
1.5 MB of empty data adds up quickly, with 1000 photos generating an additional 1.5 GB of lost space. The NeoFinder development team has informed Apple of the image capture bug.
