Magic Mouse 2 is not working in the macOS 27?

Magic Mouse 2 Stopped working completely after update for MacOS 27. It was working perfectly (in the way of a Magic Mouse) prior the update.

Now it shows it is paired and connected, but still no moves, no clicks and so no gestures. It stop completely only showing in the bluetooth that it is connected.

Anyone else with a similar problem?

Already tried disconnecting, re-paring and so on... nothing works until now.

Currently using a MacBook Air:

Trackpad working properly and another common mouse bluetooth also.

I turned on my Mac mini with macOS Tahoe and the Magic Mouse 2 is working perfectly.

Still... I get some logs and will share. Looks like that the handshake problem still persists... but for some reason the mouse works. Maybe they did a workaround for it to work? Not sure, and I don't care. But the point is, Magic Mouse is working properly in Tahoe but not on 27.

I will try to compare the logs later this day

It features a USB-C port and includes a woven USB-C Charge Cable that lets you pair and charge by connecting to a USB-C port on your Mac, so you can charge all of your favourite devices with just a single cable.

Apple sometimes delivers Firmware for their accessories

Though, there is No Direct URL to download the Firmware

That is usually done by Apple in the Background and without a User Direct Intervention

I have a Magic Mouse 2 with usb-c to lightning port.

Not sure if assuming the external hardware conector is enough.

Also, I discovered in the log that in Mac OS 26 happens a WindowServer in the very last line:

2026-09-16 08:43:31.559077-0300 0x99b      Info        0x0                  105    0    WindowServer: (CoreUtils) [com.apple.bluetooth:CBDiscovery] Device found: CBDevice 07919989-33E5-B8B1-1405-ED427C237CC5, BDA <private>, Nm <private> , PID 0x0269 (?), PrNm Magic Mouse, VID 0x004C, VS 1, DsFl 0xA00000 < Connections Pairing >, DvF 0x40000024000 < ClassicPaired HIDBadBehavior Connectable >, DvT Mouse, RSSI -56, CnS 0x800020 < HID ACL >, SupS 0x20 < HID >, Freq 2.4, Battery M -64%, ClkH L NoiseManagement R NoiseManagement, FV '1.9.2', LsnM Transparency, LsMC 0x6 < ANC Transparency >, BTv 3.0, MicM Auto, Plcm M Enabled, Prim Unknown, Invl 11.25ms, srMd Disabled, spAM ContentDriven, HaSp No, HtSp No, CF 0x0 < >, initial

That doesn`t happen in the 27. Maybe a fallback event?

If I had to speculate I would say that the flag 0x40 makes the fallback not be triggered. And that was what makes versions 1.x.x keep working.

The versions 3.x.x probably are already working in the initial hid handshake, not needing the fallback action.

Well... I would love to have access to the code...

I am talking about generations and commercially spoken names. In Brazil is conventional to name the usb-c pure as Magic Mouse 3, as a certified resseller below uses:

Anyway I am not attached to names and terminologies we can name it tragic cat, barrel monkey or jumping dinossaur…

The point is that several users are reporting problems with evidences, logs and prints.

If yours is working it is excelent for you…

But if you really wish to help us, please send us a log of what happens when you turn you mouse on in the terminal. So we can compare and figure out if there’s a workaround to do before an oficial fix.

log stream --predicate 'subsystem == "com.apple.iohid" AND composedMessage CONTAINS[c] "Magic Mouse"' --info --debug

Life saver! For those like me that dont know anything about developing and coding i just pasted the github link to chat gpt and asked it to walk me step by step on resolving the issue based on the site instructions. It took about 40 minutes copy pasting but now mouse works fine. 🫡

It seems that Bluetooth isn't working at all. It wants to connect to my AirPods (The one thing I never want it to do.) It briefly connected to my Apple Magic Keyboard, but then it dropped it. My Logitect "MX Master 3S for Mac" never appears at all. It's a real pain. There's no Bluetooth icon in the top menu.

My 2021 MacBook Pro was repaired and I reloaded from Time Machine. Apple of course automatically returned my MBP with Golden Gate 27.0 on it. It's not an Intel Chip machine. I guess I'll call Apple Care, do that shuffle and then dig back into Time Machine are reinstall the old OS....

I also suggest all that are having this problem that open a bug report too:

Feedback - Magic Mouse - Apple

I think that it maybe helps Apple to prioritize this issue.

Thanks for the reply. I only did not tested yet the 1 min cooldown with the cable. I will try when back at home.

But before, when using the macOS 26 I changed the same Magic Mouse between a macmini m4 and a my currently MacBook without any problems.

After the update, the pairing is only recognizing it but without any actions: click, move, gestures.

I tried first without the other bluetooth mouse… but I’ll try this out top since I used other mouse in the beginning of the diagonais.

I have an iPad here too and not sure if it is interfering in the diagonis someway (never paired the Magic Mouse with it). But I’ll try isolating it too.

I’ll post the results later.

Thanks for the reply.

FWIW, I haven't used a Magic Mouse 2 for at least a year. I connected the one I did use to my M3 iMac running macOS 27 and it worked right away. Moving, scrolling, clicking, right clicking all work.

I had the same issue with Magic Mouse (lightning model) after updating to macOS27 Golden Gate.

I have also already attempted disconnection, re-pairing, connecting via usb charge for firmware update and all related troubleshooting steps; but the issue persists.

Magic Mouse seems to be connected but it does not respond.

(I had to buy a USB Logitech just for that but now I've lost one port.)

Is there any official answer to that bug?

Any tested way to fix it?

My firmware:

Magic Mouse de Fábio:

Address: D0:03:4B:FF:65:C4

Vendor ID: 0x004C

Product ID: 0x0269

Firmware Version: 1.9.2

Minor Type: Mouse

RSSI: -55

Services: 0x800020 < HID ACL >

For what I have read, looks likes it is possible a cap due to the microcontroller of the Magic Mouse. Magic Mouses 2 can have different microcontrollers...

I just want to clarify something, The Magic Mouse 2 was discontinued in 2024. The replacement is the Magic Mouse (USB-C). Since my Magic Mouse 2 works fine with macOS 27 and my firmware is 3.1.1, I have to surmise people are having problems with the newer Magic Mouse.

Now that's is new for me! Until now I was thinking that it was a problem just with the Magic Mouse 2 firmware 1.X.X. Is your mouse model USB-C to USB-C or USB-C to lightning port? Can you share it please?
