Operating Systems for Devs: A Practical Guide Choosing the right operating system affects daily work for developers. It changes how quickly you install tools, run tests, and move code from idea to production. A practical setup balances stability, compatibility, and personal comfort, so you can focus on code rather than system quirks. Three common bases work well in different contexts: Windows, macOS, and Linux. Each has strengths and tradeoffs.
