macOS
Domain: Installation & Setup
Motivation
On macOS, dsh runs on the Node runtime with its own bin/system.node addon (from the node-addon-system platform package) rather than the Linux Landlock/flock binaries. A developer cares because native behavior differs on macOS and there is no Linux-style landlock-run launcher there.
Concrete Example
The node-addon-system macOS platform package provides bin/system.node for the running Node process.
Analogy
Like the same app running with a Mac-specific plugin loaded.
