When Yam Display is running with USB connected but still in ‘Wait for connection’ state, follow these steps. Try again after each step:
- Unplug USB cable and plug in again.
- Check if your device is recognized by iTunes. If not, please check out this guide.
- Make sure that you have the latest version of Yam Display and restart both apps.
For some cases macOS Sierra does not recognize connected devices after reboot. Reconnecting USB cable may solve this issue.
