Idle

Idle is a minimalist and open-source emulator of the Apple Lisa computer, designed to replicate its software and hardware environment. Developed by Gilles Fetis, it aims to provide a functional experience on modern systems, though its name (Incomplete Draft of a Lisa Emulator) reflects its ongoing development status.

Compatible with macOS, Idle targets computer history enthusiasts and users looking to run original Apple Lisa software. Its clean interface and BSD-licensed source code make it a suitable tool for developers or nostalgic users exploring this legacy without major compatibility issues.
