The Image Capture app , which is present on every Mac, allows us to import images from external media such as hard drives or cameras. Recently some developers discovered a bug in the app’s operation that causes the imported images to take up more space than usual .
Blank space seen in a binary editor.
By default our iPhone or iPad captures images using a CTA format. When we import content from an iPhone or iPad using this tool, we can decide whether we want to use the original format (CTA) or convert the images to JPG format .
The app error appears just when unchecking Keep originals , the option that causes the app to convert the content to JPG. The conversion is done correctly and the file is perfectly valid, yet 1.5MB of white space is added .
Clearly if we import 10 photos the difference is almost negligible, but if we import 1000 we have 1.5GB of occupied space without real data. It should be noted that this error only occurs when importing photos from Apple devices , which use the CTA format to capture them.
Solution? Simple. We can use the Image Capture tool to import the images in CTA format and do the conversion afterwards using the Photos app, for example.

The discoverers of the bug, the team responsible for the NeoFinder app, have already informed Apple of the situation, so we will surely see a correction of this error in a next software update.
