Can't sync Microsoft Designer Bluetooth Mouse to my Macbook

I have the same issue too. I'm using a Macbook Air late 2010 with my macOS upgraded to 10.12.1 Sierra.

But I just can't even detect my Designer Mouse via Preference > Bluetooth.😢

Vivianlzoku might be right. It seems that the Designer Mouse only support devices with Bluetooth 4.0 and up.

First,Make sure the Bluetooth version of your Mac device is 4.0 or higher

Then:

1. Shut down the mouse

2. Push the power button for more than 5 seconds (try to avoid pushing other buttons)

3. Blue light underneath starts blinking and the mouse appear on the bluetooth devices list

4. Pair it

Have you checked to see if the Microsoft mouse drivers are suited to El Capitan. Apple specifically designed a mouse for this OS.

I have the same mouse, running OS X 10.11.6 on a MacBook Pro 13in (Unibody Mid 2009), and the same issue. Oddly the mouse shows up in bluetooth paring on my iPhone6+ but nothing on my Mac. Even more odd is that my iPhone6+ will show in the pairing on the Mac even though the mouse won't. I did try going into mice and seeing if it would show/pair there and it did not.

I see a few threads reporting bluetooth mouse issues with 10.11 and 10.11.6 ... thinking about reloading with 10.10 to see if that helps...

I have found the cause of issues. The Microsoft Designer Mouse is bluetooth v4.0 compatible only (according to Microsoft) and has a limited range of Mac OS X compatibility of 10.9-10.10 (again according to MS). My MacBook Pro 13in (Unibody Mid 2009) has Bluetooth v2.1 which explains why it does not work. There are many issue reports with bluetooth pairing across multiple OS that likely relate to bluetooth version compatibility.

Luckily for me I have another bluetooth MS mouse that I use with my Asus Transformer. The Designer Mouse works fine on my Transformer and the other bluetooth MS mouse works fine on my MacBook so I will just switch them. Good luck to you and hope this helps anyone else with issues related to this mouse.

Nothing to do with drivers for the Designer Mouse. It is related to bluetooth version compatibility. The Designer Mouse only supports bluetooth v4.0

The Microsoft Bluetooth Designer Mouse shows up as a Bluetooth device, not as a mouse. Don't know why, but it does. It should be on the same page as an Apple Bluetooth keyboard. Once paired, it works well, although I have experienced some problems with it when my system sleeps after upgrading to Sierra.

Charles, is the issue you've been having with Sierra that the mouse won't work/reconnect until it's paired again if:

• The mouse is turned off and then back on;
• After the system sleeps
• After a system boot/restart
• If the mouse is left untouched long enough for its power saving mode to kick in

If so, there's a few of us having the same issue but with the Microsoft Arc Touch Bluetooth mouse.
