Raspberry Pi Imager
Raspberry Pi Imager is a macOS utility for downloading and writing Raspberry Pi OS and other system images to microSD cards.
What is Raspberry Pi Imager?
Raspberry Pi Imager is a desktop utility for preparing microSD cards for Raspberry Pi computers on macOS. It helps users download Raspberry Pi OS and other supported operating system images, then write them directly to removable storage for use in a Raspberry Pi device. The app is aimed at beginners setting up a board for the first time as well as hobbyists, educators, and developers who reimage cards regularly. It can also load image files you have already downloaded manually, which is useful for custom setups and third-party operating systems. During setup, it supports preconfiguring options such as credentials and remote-access settings before writing the card, which can streamline first boot and deployment workflows. On a Mac, most people use it when installing or reinstalling software for a Raspberry Pi, testing different operating systems, or preparing multiple cards for projects and classrooms.
Key features
- Download Raspberry Pi OS and other supported operating system images from within the app
- Write operating system images directly to a microSD card for Raspberry Pi devices
- Use manually downloaded image files for custom or third-party operating systems
- Preconfigure setup options before first boot, including credentials and remote-access settings
- Prepare cards for first-time setup, recovery, reinstallation, or repeat deployment workflows

Safety overview
Status: Safe
This app is a standard device-imaging utility. It needs access to removable storage so it can erase and write a microSD card, which is normal for its purpose. The main practical risk is selecting the wrong disk, because writing an image replaces the existing contents of the chosen card or drive. Use it with the correct removable media inserted, and double-check the selected target before starting a write.
Recommendation: Keep Raspberry Pi Imager if you set up, reinstall, or experiment with Raspberry Pi systems on your Mac. Remove it if you no longer use Raspberry Pi hardware and do not need to prepare microSD cards, knowing that deleting the app will only take away this imaging workflow until you reinstall it.
