Turn on USB debugging

1. On the phone open Settings → About phone and tap Build number seven times to unlock Developer options.
2. Open Settings → System → Developer options (the path varies by brand) and turn on USB debugging.
3. Connect the phone with a USB data cable and, when asked, tap Allow on "Allow USB debugging?". Tick "Always allow from this computer" to avoid repeating it.

Common problems

The phone does not appear

Try another cable (some only charge), another port, then unplug and replug. On the phone set USB mode to File transfer. Revoke USB debugging authorisations in Developer options and connect again.

It says "unauthorized"

Unlock the phone and accept the debugging prompt. If it never appears, revoke USB debugging authorisations and reconnect.

The mirrored screen is black

Some apps (banking, video with DRM) block screen capture on purpose. Make sure the phone is unlocked and awake.

Copying stops or fails

Check free space on the destination and that the cable stays connected. Retry; a partly copied file is cleaned up.

Wi‑Fi connection

Phone and Mac must be on the same network. Enable Wireless debugging in Developer options and pair it first.
