Third hit: a weird, half-translated page from a site called "xiaomi-drivers.cn" that demanded he download a 450MB file called "Mi_Mouse_Utility_Setup_v2.3.exe". The comments below were in broken English: "This is virus. Do not install." and "Works for my RedmiBook! Thanks!" and then, chillingly, "My computer no turn on after."
"Xiaomi mice report wrong battery level to macOS. macOS then throttles the HID report rate to save power. This script forces the polling rate back to 125Hz. Use at your own risk."
Finally, at 3:15 AM, the script ran.
He spent the next forty-five minutes installing Homebrew, then pybluez, then giving Terminal permission to access Bluetooth, then disabling System Integrity Protection in Recovery Mode because the script needed low-level access.

At 9:00 AM, he delivered the presentation. No one noticed the smooth cursor. No one saw the beautiful matte-gray mouse. But Leo knew. He had traveled to the edge of the internet, fought the ghosts of driver-update scams, and returned with a Python script.
He tried the Reddit fix: plug the USB-C hub into the other side of the laptop. No change. He tried moving the Bluetooth dongle for his headphones farther away. No change.

Leo’s microwave was off. But his desk was a mess of interference: a Wi-Fi 6 router, a USB 3.0 hub (known for 2.4GHz noise), three wireless keyboards for different devices, and his phone hotspot. The air was thick with competing radio signals. Third hit: a weird, half-translated page from a
The problem was macOS.
He finished his presentation at 5:50 AM. The Xiaomi mouse worked perfectly for the entire six hours.
He opened Terminal. He typed python3 fix_xiaomi_mac.py . It spat back: ModuleNotFoundError: No module named 'pybluez' Thanks
The cursor had started to stutter, then freeze, then vanish entirely for seconds at a time. The scroll wheel had developed a mind of its own, jerking his Figma canvas to random zooms. Leo had done what any logical person would do: he turned the mouse off, then on. He removed it from Bluetooth devices and re-paired it. He changed the battery, even though the Xiaomi app on his phone said it was at 78%. Nothing.

First hit: a sponsored ad for "DriverFix 2024 - Scan for Missing Drivers!" Leo had been burned by that before. That was the path to bloatware and a hijacked homepage.
