Lazarus
Lazarus is a free, open-source integrated development environment (IDE) for the Free Pascal Compiler (FPC). It provides a visual programming environment for building self-contained graphical and console applications for macOS, Linux, Windows and FreeBSD. Lazarus targets developers who want rapid application development with a modern Pascal implementation that supports generics, managed arrays, interfaces and other contemporary language features. The IDE includes code completion, a visual form designer, and integrated debugging tools.

1 suggestionLazarus has shipped a native Apple Silicon build since version 2.2.x (released around late 2021/early 2022), distributed as a Universal Binary that runs natively on M-series Macs. If you are running an older Intel-only build under Rosetta, update to the latest version to see better performance and battery life. The simplest path is to use Homebrew: run `brew install --cask lazarus` in Terminal, which will automatically fetch the current Universal Binary for your Mac's architecture. Alternatively, download directly from lazarus.freepascal.org or sourceforge.net/projects/lazarus/ — the official installer page now ships the Universal Binary by default on modern macOS systems. If you prefer to compile Lazarus from source using FPCUpDeluxe, ensure you have installed the ARM64 cross-compiler (aarch64-darwin) alongside your Intel compiler so both architectures are available.
