Wired companion and host tuning

Streemi.ng’s normal Wi-Fi display mode works without host software. The experimental wired mode uses the macOS Streemi.ng Companion with a compatible Android Open Accessory USB connection.

Download and run the companion

Download streaming companion for Apple silicon (macOS 14 or newer). Open the ZIP, move Streemi.ng Companion to Applications, then start monitoring from its window or menu bar. The published route appears as <tablet name> (wired) in Control Center → Screen Mirroring after its USB test completes.

This is an experimental arm64-only build. It is ad-hoc signed and not notarized unless the release’s included Release Metadata.txt states otherwise. Review that file and the accompanying SHA-256 sums before using the download; macOS may require an explicit user approval. Release metadata and SHA-256 checksum are available beside the download.

What wired mode does

Companion watches for supported USB tablets, retries a disconnected device, publishes a wired AirPlay display route only after the relay is ready, and withdraws it safely when monitoring stops. Its menu bar can show connection help, optionally launch at login, display link/test status, and adjust tablet brightness after Android permission is granted. It does not automate macOS Control Center.

Higher bandwidth experiment

Run this on the Mac, then restart the display connection. Remove the overrides if quality or stability gets worse on your setup.
