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.

Same here: Mac mini M4, macOS 27.0, Magic Mouse 2 (0x0269, firmware 1.9.2).

I think I found what the driver is skipping. On macOS 26 the mouse receives a feature report that switches it out of boot-mouse mode into multi-touch mode. On 27 that report is never sent, so the mouse connects, reports its battery, and then just sits there waiting. The Linux hid-magicmouse driver sends the same four bytes: F1 06 01 37.

Sending it by hand brings the mouse back instantly. I put up a small program that does exactly that - one C file, no binary to trust, no network, nothing left running unless you install the optional LaunchDaemon:

https://github.com/oleksandr-antonian/macos27-magic-mouse-fix

Credit for spotting the report goes to o0mohd0o/MagicMouseFix - I verified it and wrote my own version so the source is short enough to read before running.

Still worth filing Feedback with Apple. This is a workaround, not a fix.

Same problem here. I did try everything that is mentioned here and that was suggested by all four leading AIs: ChatGPT, Grok, Claude, Gemini, and nothing worked. The mouse connects and is active but does not click or move after updating to macOS 27 Golden Gate. Then I tested the mouse on my iPad that I have also updated to iPadOS 27, and the problem was the same, connects and active but does not move the cursor or click. I even started thinking that there was a hardware problem with the mouse, because my Magic Keyboard works just fine after the update on both devices. Funny thing is that when I decided to try the mouse again on my older iPad with iPadOS 26 installed still, and Magic Mouse started working!!! So it seems like there is a software issue with the MacOS 27 and iPadOS 27, that makes the mouse not work, will need to wait for the bug to be patched in future updates.

For sure.

But I think that for non-devs the solution of

https://github.com/o0mohd0o/MagicMouseFix

already described in the xander-ag repos readme could be enough.

I would give it a try first. There is a small interface for installation and so on, like a default behavior.

If it not works or anyone still needs a hand I can give a small tutorial step by step in the xander-ag method, that is already a proven solution for me.

Hardware: Mac mini (2024, M4), 16 GB

OS: macOS 27.0 (26A428)

Device: Magic Mouse 2, firmware 1.9.2, VID 0x004C, PID 0x0269

SUMMARY

After updating to macOS 27.0 the Magic Mouse 2 pairs and shows as

Connected with a battery level, but sends no input at all. The Mouse

pane in System Settings is empty. A Magic Keyboard on the same Mac over

the same Bluetooth stack works normally, as does a non-Apple Bluetooth

mouse. The same Magic Mouse works correctly on another Mac running

macOS 26.

STEPS TO REPRODUCE

1. Update a Mac to macOS 27.0.

2. Pair a Magic Mouse 2 (firmware 1.9.2).

3. Move the mouse.

EXPECTED

Pointer moves, clicks and gestures work, Mouse pane shows settings.

ACTUAL

No pointer movement, no clicks, no gestures. Mouse pane empty.

DIAGNOSIS

The mouse never becomes an HID device:

ioreg -c IOHIDDevice -> no Magic Mouse entry

ioreg -c IOBluetoothHIDDriver -> no instance

ioreg -c AppleMultitouchDevice -> no instance

bluetoothd flags the device on every connection:

DvF 0x40000024000 < ClassicPaired HIDBadBehavior Connectable >

CnS 0x800020 < HID ACL >, SupS 0x20 < HID >, Battery M -65%

Magic Keyboard on the same host, working:

DvF 0x40000114000 < ClassicPaired HIDGoodBehavior ConnectedOverUSB Connectable >

Telemetry in the same log: ConnectedClassicHIDDevice : 0

The reported battery level is negative (-65%) while ControlCenter, in

the same log, reports the same device correctly as batteryLevel: 0.65.

Another user reports -63% at 63% charge with identical symptoms

(discussions.apple.com/thread/256357286).

This suggests a sign error when parsing the Magic Mouse battery field,

causing the device to be classified HIDBadBehavior, which prevents the

HID profile from attaching.

ALREADY RULED OUT

Re-pairing, pairing by cable, pairing from a cleared device list,

Bluetooth reset, multiple reboots, Safe Mode, resetting

com.apple.AppleMultitouchMouse and

com.apple.driver.AppleBluetoothMultitouch.mouse preference domains.

None survive a reconnect, because the flag is recomputed each time.

Version 27.2 has fixed the issue in my Macbook M5 Pro.

You would have a faster fix if reinstall to macOS 26 Tahoe. The macOS 27 still needs a bug fix that is addressed to Apple.

I would say that it usually happens in some weeks after the first launch. If is mandatory to you to use the Magic Mouse now, the faster solution is installing macOS 26.

Similar problem. Magic Mouse 2 doesn’t work after updating to Mac OS27. I tried it on M1 and M2. At the same time, Magic Mouse 1 works with these laptops on Mac OS27. And Magic Mouse 2 works with older Mac OS versions. The issue is clearly with Mac OS27.

The problem also affects iPadOS 27, it seems to have resolved on macOS 27.2 but iPadOS 27.2 still has a problem.

Still not working... I copy pasted the diagnosis in a AI Chatbot and looks likes it can change something related to a fail in the handshake: HIDBadBehavior

The problem is that the mouse is with above 60% battery. The system is measuring it in -63%. What sounds weird....

Also, after letting it charge a bit (the recommendation of 1 min) It goes up to 65% and I did another shot and read the logs:

bluetoothd: (CoreUtils) [com.apple.bluetooth:CBPowerSource] Power source updated CBPowerSource Nm 'Magic Mouse de Fábio', SID 56164353, AcCa Mouse, AcID A0FF161D-DFC3-B8EB-9622-A904E46E2E62, PID 0x0269 (?), VID 0x004C (Apple), Type 'Accessory Source', TPT Bluetooth, CF 0x1 < Attributes >, IF 0x2 < IOKit >, Present yes, MaxC 100%, Battery -65%

Not sure if the battery is correlated with the problem, but the problem is: Magic Mouse is not accepting the handshake. And the battery is working properly.

Do you mind to share your Magic Mouse firmware? There is a user here that is working using a firmware 3.1.1. Mine is 1.9.2.

I am trying to check if this is correlated.

Thank you for the help in the investigation.

I think this is a glitch in Mac firmware showing in interface. Mine did the same when I plugged it in.

The right firmware is what shows you when it is disconnected.

You can also use in the terminal:

system_profiler SPBluetoothDataType | grep -A 20 "Magic Mouse" | grep "Firmware Version"

If you provide us with further logs we can compare and check if there are something that we can do or report.

I think that you are facing a mesa in the Mac foruns. For some weird purpose it is not timeline based so you need to take out the “sort by rank”:

I think that the possible problem is the quarantine. Try use this command:

sudo xattr -d com.apple.quarantine /Library/LaunchDaemons/com.local.magicmousefix.plist

After that:

Run again

sudo launchctl bootstrap system /Library/LaunchDaemons/com.local.magicmousefix.plist

Thanks for the reply. I tried it also, but even in security the problem still occurs. Just another different version of the macOS can support my current Magic Mouse Version 1.9.2... Sad, but true.

Sep 15, 2026 7:34 AM in response to fábio161

I'd first try restarting the Mac.

If that does not fix it, try forgetting the mouse and then pairing it again with your mac.

Magic Mouse 2 is not working in the macOS 27?
