Arduino IDE
Arduino IDE is a desktop integrated development environment for writing, compiling, and uploading code to Arduino boards and compatible devices.
What is Arduino IDE?
Arduino IDE is a desktop integrated development environment for creating programs for Arduino boards and other supported microcontroller platforms. It helps students, hobbyists, makers, and professional developers write sketches, verify code, and upload firmware over USB or other supported connections. The app includes code editing, serial monitoring, board and port selection, and tools for installing board packages and libraries needed for different hardware. It is commonly used for electronics prototyping, robotics projects, classroom labs, and embedded programming workflows on macOS and other desktop operating systems. Arduino IDE is published by ARDUINO SA and is designed to provide a straightforward workflow from writing code to testing it on connected hardware.
Key features
- Write and edit Arduino sketches in a desktop code editor
- Compile code and upload it directly to supported boards
- Monitor serial output for debugging and device communication
- Install and manage board packages for different hardware platforms
- Add libraries to extend hardware support and project capabilities
- Select connected boards and ports from within the app

Safety overview
Status: Safe
Arduino IDE is legitimate developer software used to program microcontroller boards. Access to removable devices and serial ports is normal for its purpose because the app needs to detect boards, upload sketches, and read serial output. It may download board packages, libraries, and toolchains, so keep those components updated and use trusted hardware and code when connecting devices. Removing the app will stop you from editing, compiling, and uploading projects with this workflow, but it does not by itself remove your saved sketches.
Recommendation: Keep Arduino IDE if you use Arduino boards, embedded projects, classroom electronics, or serial-device development on your Mac. If you no longer use it, you can remove the app, but keep any project folders you still need before cleaning up related support files.
