I am unable to pair with MacOS over Bluetooth.

If your mouse is not appearing in your Macs Bluetooth device list when put into pairing mode, or not connecting when it does. Please try the Bluetooth troubleshooting steps below.

If the LED on your mouse is a constant RED when you switch it on it needs to complete a firmware update before you will be able to pair with it. Instructions to do this can be found here.

Basic troubleshooting:

Remove all existing Bluetooth pairings related to your mouse, restart your mac, and perform a factory reset  of your mouse before attempting to re-pair.

Remove your Bluetooth preferences list:

This file can cause problems connecting with Bluetooth devices if it is corrupted. Removing it will allow it to be recreated.
  1. Open a Finder window and navigate to /Macintosh HD/Library/Preferences. 
  2. Scroll through the list until you find the file called 'com.apple.Bluetooth.plist'. 

  3. Select the com.apple.Bluetooth.plist file and drag it to the desktop. This will create a copy of the existing file on your desktop; we're doing this to ensure that we have a backup of the file we're about to delete. 
  4.  Right-click the com.apple.Bluetooth.plist file and select Move to Trash from the pop-up menu.
  5. You'll be asked for an administrator password to move the file to the trash. Enter the password and click OK.
  6. Close any applications you have open. 
  7.  Restart your Mac.
Once you're sure that your Bluetooth problem has been resolved, you can delete the backup copy of com.apple.Bluetooth.plist from your desktop. Should the problem continue, you can restore the backup copy of com.apple.Bluetooth.plist by simply copying it back into the /Macintosh HD/Library/Preferences folder.

Reset your Bluetooth hardware module:

This Bluetooth debug option restore your Bluetooth module to default settings, which will also remove all connected Bluetooth devices.
  1. From the OS X desktop, hold down the Shift+Option keys and then click on the Bluetooth menu item to reveal the hidden Debug menu.
  2. From the drop-down menu select Debug, Remove all Devices.
  3. Now open the Bluetooth menu again with Shift+Option held down, and select the “Reset the Bluetooth module” option.
  4. Select Debug, “Reset the Bluetooth module” from the Debug menu list.
  5. When finished resetting, reboot your Mac as usual.
