Zac-OS-9: The classic Platinum desktop, reborn for modern PCs
Summary
Zac-OS-9 is a complete Mac OS 8/9-inspired desktop for Debian Linux, rebuilt from scratch to mimic the classic Platinum UI. It includes a pixel-faithful windowing environment, the Zac menu with desk accessories, and can run Debian/Flathub apps, classic Mac OS through SheepShaver, and even Windows programs via Wine. The project is open source under GPL and emphasizes portability and ease of trial via USB live demos.
