Thonny
Thonny is a beginner-friendly Python IDE for macOS that helps learners write, run, debug, and understand Python programs in one app.
What is Thonny?
Thonny is a native desktop IDE for learning and using Python on macOS. It is designed especially for beginners, students, and educators who want a simpler environment for writing code than a full professional development suite. The app includes an editor, Python shell, debugger, and variable inspection tools so users can run programs and see how code behaves step by step. Thonny also supports package management and extension plug-ins, which makes it useful beyond first lessons as users grow into larger projects. It is commonly used in programming classes, self-study, and introductory scripting workflows. Thonny is published by Aivar Annamaa and focuses on making Python development easier to understand from the first launch.
Key features
- Write and run Python code in an integrated editor and shell
- Step through programs with a beginner-friendly debugger
- Inspect variables to see how code changes program state
- Manage Python packages from within the app

Safety overview
Status: Safe
Thonny is legitimate programming software for writing and running Python code. It normally needs access to files you open or save in your projects, and that behavior is expected for an IDE. If you use package installation features or external Python tools, be mindful that third-party code you add can affect your development environment. Keep the app updated and install packages only from sources you trust.
Recommendation: Keep Thonny if you use Python on this Mac, especially for learning, teaching, or lightweight scripting. If you no longer use it, you can remove the app and its support files to free space, but doing so may also remove your IDE settings and local project-related preferences.
