NeoFinder, the developer of media management software for the Mac, has discovered a space-wasting bug in Apple's built-in photo and scanner tool, Image Capture.

How does it work? When you use Image Capture to import photos from, say, an iPhone or iPad, you have the option to convert them to JPEG when you get them to your Mac, rather than importing them as the default HEIC format.

To do this, uncheck the "Keep originals" checkbox in Image Capture and then import. However, when you did this, the developers discovered that each imported photo file contained an additional 1.5 MB of useless data (see image below).

Big picture: If you have a MacBook with a smaller SSD in it, you could be wasting gigabytes of data this way. With just 1,000 photos imported this way, you’d be looking at 1.5GB of wasted space. That’s a lot when your MacBook only has 128GB total.
