Many Mac users rely on the Image Capture app to transfer photos and videos from directly-connected cameras, memory cards, iPhones, and iPads. It’s an alternative to Photos (or iPhoto) if you’re not using iTunes for syncing, manually importing, or using iCloud Photo Library.
But sometimes you may plug in your iOS device and Image Capture fails to show it listed in the left bar that shows devices from which it can acquire media. This appears to happen due to a trust issue. MacOS has been gradually upping how it closes a verification loop between an iPhone or iPad and software on a Mac when you connect the iOS device via USB. That’s good for security—someone might be able to grab your device, plug it in, and rifle through data and media.
