Make a USB drive with one small program that downloads the latest Meccanic OS, checks it, and makes a USB stick (16 GB or larger) bootable with Ventoy, with Meccanic OS on it. On macOS, where Ventoy does not run, it writes Meccanic OS directly to the drive. Windows users double-click mos-usb-windows.exe; macOS and Linux users run terminal curl and chmod commands. Every drive includes a Meccanic OS-README.pdf explaining how to start the computer and adjust BIOS settings.
Built on Nix OS as one coherent system instead of unrelated Linux tools, Meccanic OS is keyboard-first: Super+Space opens one command bar for apps, commands, websites, folders, and questions. It works offline, with the desktop, included apps, and drivers on the stick. Installed systems use LUKS2 whole-disk encryption; live sessions stay in memory with encrypted vaults and persistent home. A hardened kernel, firewall, and login alerts are included.
The whole system is one Nix flake, so upgrades are atomic and rollable back. It ships with Mesa, Vulkan, NVIDIA drivers, Pipe Wire, Bluetooth, printers, and scanners. Users can search nixpkgs' 120,000 packages, try apps without installing, or run local AI (Qwen3 via Ollama, ~2.5 GB). Other features include encrypted Time Machine-style backups, Piper read-aloud, and one-key disconnect.
