My Fitbit Charge 2 has stopped syncing with my MacBook Pro

Hi mundyabney,

Re: "My Fitbit Charge 2 has stopped syncing with my MacBook. What can I do?"

Wondering if you need to update your MacOS to a newer version to keep the two compatible:

Apple support's article: Identify your MacBook Pro model - Apple Support may help:

Else:

You may need to update the firmware on your fitbit from time to time:

From: "Fitbit Charge 2 Manual": Page: 24 https://help.fitbit.com/manuals/manual_charge_2_en_US.pdf

"Update Fitbit Charge 2

We occasionally make free feature enhancements and product improvements available through

firmware updates. We recommend keeping your Charge 2 up to date.

When a firmware update is available you’ll see a notification in the Fitbit app prompting you to update.

When the update starts, a progress bar appears on the tracker and in the Fitbit app until the update is

complete.

Keep your tracker and phone close to each other during the update process.

Note: Updating your Charge 2 takes several minutes and may be demanding on the battery.

For this reason we recommend updating while your tracker is fully charged or plugged into the charging

cable."

All the best :-)
