Magic Mouse 2 not working after macOS 27 update

Hi everyone,

I'm having a serious issue with my **Apple Magic Mouse 2 (Lightning version)** after updating my **MacBook Neo** from macOS 26 to **macOS 27**.

**Before the update:** The mouse worked perfectly, no issues at all.

**After the update:**

- The mouse connects via Bluetooth. In settings, it shows the battery level and firmware version **1.9.2**.

- When connected via Lightning cable, the system shows firmware version **8.6.0**.

- **The main problem:** The sensor does not work. The cursor does not move, and no buttons respond. The mouse is recognized by the system, but does not function as an input device.

What I've already tried (all standard troubleshooting steps):

- Removed the device from Bluetooth list and re-paired it.

- Reset the Bluetooth module (Option + Shift → Reset the Bluetooth module).

- Rebooted the MacBook (normal restart and full shutdown).

- Connected the mouse via cable and left it charging for several hours.

- Checked Bluetooth settings in the system — everything is enabled correctly.

- Tried connecting the mouse to another device — it works there, so the issue is specific to macOS 27.

- Deleted mouse plist files to reset settings.

All standard solutions recommended by Apple and found in official sources have been tried. None of them worked.

Additional information:

- Device: MacBook Neo

- macOS version: 27

- Mouse model: Apple Magic Mouse 2 (Lightning)

- Mouse firmware (via Bluetooth): 1.9.2

- Firmware shown when connected via cable: 8.6.0

Question: Is this a known compatibility issue between macOS 27 and Magic Mouse 2? If so, when can we expect a fix? If not, what else can I try?

Any help would be greatly appreciated.
