Quick fixes
The phone is not found
Use a data cable — some cables only charge. Plug it into the Mac directly, not into a hub or monitor. On the phone, turn on USB debugging (the app shows how), then tap “Allow” and check “Always allow from this computer”.
“Another adb is using the phone”
Another tool (a developer tool or another mirroring app) is holding the phone. Quit it, or run adb kill-server in Terminal, then reconnect the cable.
I can see the screen, but taps and keys don't work
Some phones need a second switch: turn on “USB debugging (Security settings)” in Developer options. Xiaomi may ask you to sign in to a Mi account for this.
The picture stutters or lags
Check the HUD: if the phone shows overheating, let it cool down or lower the game's graphics. Close heavy apps on the Mac, use a short, good cable, and plug it directly into the Mac.
The cable came loose
Just reconnect it. The game and the control mode resume by themselves.
macOS says it can't check the app
Open System Settings → Privacy & Security, scroll down and click “Open Anyway” next to Tethercast. You need to do this once.
My license key is not accepted
Copy the whole key from the e-mail — line breaks are fine. If the app says the key needs a newer version, choose Tethercast → Check for Updates…
I didn't get my key
