5.2   Why isn’t my device connecting?

ToothFairy works with devices that can be connected to your Mac via the macOS Bluetooth menu. If you can connect it via the system menu, you should be able to connect and disconnect it via ToothFairy. Here are some steps to try if you can’t get your device to connect or if it won’t stay connected:

  1. Make sure that Bluetooth is On in the Bluetooth pane in System Preferences. It can help to turn Bluetooth off and then back on again on your Mac, or to turn it off on other nearby devices.
  2. Make sure that your device is paired with your Mac using the Bluetooth pane of System Preferences. It sometimes helps to unpair the device in System Preferences and then re-pair it. (Just because you can see the device and connect to it from the Bluetooth menu does not mean that it is paired. Make sure that you check System Preferences.)
  3. Make sure that the device you are trying to connect is the same one that you added to ToothFairy. For example, if you got a new pair of AirPods, ToothFairy will still try to connect to the old AirPods (and report a timeout error) unless you’ve added the new ones to ToothFairy using the + button. Even if you haven’t gotten a new device, it can sometimes help to remove the device from ToothFairy using the - button and then add it back using the + button.
  4. Make sure the device’s battery is fully charged.
  5. Try restarting your Mac in Safe Mode. This will help rule out other software as the source of the problem, but it can also fix the problem (i.e. the Bluetooth device will continue working after you do a regular reboot).
  6. It can help to adjust your AirDrop settings (on your Macs and any nearby iOS devices). Bluetooth devices connect more reliably when AirDrop is off or set to Contacts Only.
  7. It can help to turn off Allow Handoff between this Mac and your iCloud devices in the General pane of System Preferences.
  8. If you have USB Overdrive installed, try temporarily turning it off or uninstalling it and see whether that helps.
  9. Try disconnecting any USB hubs from your Mac or nearby Macs.
  10. Check Apple’s Potential sources of Wi-Fi and Bluetooth interference guide.
  11. Try resetting your Mac’s Bluetooth module. You can do this by holding down the Shift and Option keys while clicking on the Bluetooth menu. Go to the Debug submenu and choose Reset the Bluetooth Module. Then restart your Mac.
  12. Apps like Bluetooth Inspector, iStumbler, and Apple’s Bluetooth Explorer can be used to diagnose connection problems.
  13. If you still can’t get it to work, save a Bluetooth log and a diagnostic report and send them to us for further assistance.
