The Intrusive Import
If you are a photographer, videographer, or simply someone who frequently transfers files using physical media, you’ve likely encountered macOS’s aggressive media handling. By default, the moment you insert an SD card or connect a camera to your Mac, the native Apple Photos app automatically bounces open in the Dock, takes over your screen, and attempts to scan the card to import all visual media. While convenient for casual users wanting to back up family vacation photos, it is incredibly disruptive for professionals who intend to browse the raw files via Finder, ingest footage using Premiere Pro, or process images in Adobe Lightroom. The Photos app essentially gets in the way of your actual workflow.
Disabling Auto-Launch via Image Capture
To stop macOS from automatically launching the Photos app every time you insert an SD card or connect a camera, you need to change the device’s default behavior using the built-in Image Capture utility.
First, insert the SD card or connect the camera to your Mac as you normally would. Allow the Photos app to launch automatically this one last time, and then immediately quit it (Cmd + Q). Next, open Spotlight Search (Cmd + Space) and type Image Capture. Press Enter to open the app. In the left-hand sidebar of Image Capture, look under the “Devices” or “Shared” section and click on your connected SD card or camera. In the bottom-left corner of the main window, look for a small drop-down menu labeled Connecting this [device] opens:. Click this drop-down menu and change the selection from “Photos” to No application. You must repeat this quick process for every unique physical device (each different camera or uniquely formatted SD card) you connect, but once set, macOS will remember the preference and never automatically launch Photos for that device again.
