At the bottom of the screen that appears, there's a box you can check that reads 'Show Bluetooth in menu bar.' Why won't my Bluetooth connect? How to fix issues Quick tip: If you don't have a Bluetooth icon on your menu bar at the top of the screen and you'd like to add it, go to 'Bluetooth' in System Preferences. From the Bluetooth icon in the menu bar, you can also turn Bluetooth on and off, or select 'Open Bluetooth Preferences,' which opens the System Preferences Bluetooth page.

That will tell you which of your connected devices is low on charge. If the dots are replaced by a low battery icon, click to drop down the menu.

If you add Bluetooth settings to your menu bar, you can connect your devices from a dropdown menu.
