magic mouse wont connect

I had problems getting my Magic Mouse 2 to sync with my MacBook Air Mid 2011 and found that the trick for getting the mouse to resync to my Mac was to make sure your lightning cable is connected to your Mac (not your iPhone wall charger) and connected to the underbelly of the Magic Mouse 2 (the unassuming unmarked connector port below the designed by Apple and no trash disposal symbol.

Once I did this my Mac immediately recognized and paired to the Magic Mouse. This is completely different than how most other bluetooth devices are synced on the Mac using bluetooth discovery mode. It'll be interesting to see how to setup this mouse with Boot Camp and Windows 10 and Ubuntu. I'm guessing they still need to iron out a few issues and support the older bluetooth pairing mode or write lightning to USB drivers.

Hmmm.... How does it connect to another Mac?

Some random things to try:

- Swap out batteries, especially if they are old rechargeable ones. Make sure your BlueTooth icon in the menu bar reports that they are >90% charged.

- Toggle off WiFi and report if your BlueTooth connection is more stable (weird, but others have reported issues in latest OS X release)

- If the problem is intermittent take some paper, fold it and wedge it between the batteries in the mouse. Some batteries are shorter than the Apple branded rechargeable ones so the electrical connection can get broken resulting in a lost mouse connection.

- Verify on another Mac or on your Mac running Boot Camp windows that the mouse is working fine. If it isn't then the problem is most likely with the mouse.

- Try adding a USB BlueTooth adapter (make sure it is Mac compatible) and see if the problem is with your Mac's BlueTooth internal adapter (sometimes it is the chip and other times it is interference from an electrical source like WiFi, big screen TV, etc).

Best of luck!

From what I understand Magic Mouse 2 only works with El Capitan 😟

As far as I can see, at no point do you say this is a new Magic Mouse 2. Had you done so, then the suggestion that it only works with El Capitan 10.11.1 would be correct. So assuming it is not MM2 here is how to re-set the PRAM and / or the SMC. You may have to follow both or either procedure more than once.

The detail on resetting the SMC is via a link towards the bottom of the document.

So I bought Magic Mouse 2 and I cant sync it... the Mac is running OS: 10.10.5 (Yosemite)... So the only way I can make it work is to upgrade to 10.11(El Capitan)?

There is no workaround????
