Troubleshooting V650 sync in FlowSync (Mac OS)

Please note, that when you plug your V650 into your computer it may take some time to establish the connection between your V650 and the computer. Be patient and wait for the sync to start.

If V650 sync doesn’t start in FlowSync or you get a “Connection error. Connection to Polar product lost.” error message, try the following steps one at a time.

Make sure you are following the syncing instructions

See How do I sync my V650 with Flow web service (Mac OS) for detailed syncing instructions.

Make sure the USB cable is connected to V650 properly

  • If your V650 doesn’t charge properly, or if it doesn’t connect to FlowSync, remove and replug the USB cable.
  • Always connect your V650 directly to your computer’s USB port. Do not connect it via USB hub, computer docking station or USB extension cable.
  • Try the other USB port(s).

Be patient and wait for the sync to start.

Restart FlowSync

Close FlowSync by clicking the icon on your menubar and choosing Close. Then restart FlowSync from Applications folder.

Restart your computer

Restart your computer while keeping the V650 connected to the USB port. V650 must be turned on and in the main view.

Restart V650

Press the side button and choose Turn off your V650, then restart the V650 by pressing and holding the side button. After the restart keep the V650 in the main view and be patient and wait for the sync to start.

Try syncing with another micro-USB cable if you have one.

Make sure Bonjour Service is running

Go to Terminal and type command:

$ sudo launchctl load -F /System/Library/LaunchDaemons/com.apple.mDNSResponder.plist

Make sure that other running software isn’t blocking the sync

Some software automatically starting while the computer is started may block the V650 sync. Close all other running software, including the ones that start automatically when you start your computer.

For detailed steps see Apple support

Restart your computer and try syncing your V650 again.
