I updated my MacBook Pro with Apple M4 Pro to macOS Golden Gate 27.0 (26A428). The wireless Magic Mouse (version 3.1.4) stopped working. It connects, but it has zero response(No click or drag actions).
Already performed actions like disconnect/connect and forget bluetooth device.
Found the same issue reddit but with a beta update. But still no answer.
Confirmed: MagicMouseFix 1.0.0 works with the USB-C Magic Mouse A3204, firmware 3.1.4, on an Apple silicon MacBook Pro running macOS 27.0. The mouse appeared connected and showed its battery level, but there was no pointer movement, clicking, scrolling, or gestures—even in Safe Mode. After installing MagicMouseFix and allowing Input Monitoring, all functions started working immediately.

Magic Mouse 2 is not working in the macOS… - Apple Community
Thank you for you suggestion, i saw that ticket, and i did not have any oner bluetooth mouse, also i do not have any utility that modifies mouse behaviour—such as Logitech Options+, BetterMouse, SteerMouse, Mac Mouse Fix, or similar.
So have only 1 mouse which was work perfect before update, and then stops working after update. Even check my mouse with another macbook pro with macOs 26.7 version, all works fine.
