A bug has been discovered in Impact Capture in macOS, which fills up a Mac's drive with empty files. This bug has been present since macOS 10.14.6, and also exists in macOS Catalina 10.15.4, and has been reported by the developers behind Neofinder.

In a blog post written by NeoFinder development team, the bug is related to ImageCaptureCore.framework used in macOS so any apps that utilize it also face the issue. When you connect an iPhone, iPad or iPod touch to a Mac, and use Image Capture tool to import photos, the images are imported using HEIC format. However, to import them in JPEG format, which is more widely used and supported, you have to enable a 'Keep Originals' option. While this option works as intended, it suffers from an issue where it adds 1.5MB of empty data to each JPEG photo.
