While the boot chime was still echoing, she clicked the M3600’s button. Not just a click. She held it. For ten seconds. The blue light stopped blinking and started pulsing, fast.
Frustrated, Lena fell into the Google rabbit hole. "bluetooth mouse 3600 driver" yielded a graveyard of dead links: a shady "DriverUpdate2024.exe" site, a Russian forum from 2017, and a Reddit thread with one reply: "It's a mouse, dude. No driver needed. Pair it."
But tonight, it refused.
She opened System Settings. Bluetooth: On . Devices: None . She pressed the mouse’s button again. Nothing. A cold dread trickled down her spine. The M3600 was discontinued. Logitech’s official site only listed "Unifying Receiver" software for older models, and the 3600 was strictly Bluetooth. There were no dedicated "drivers" for a basic HID (Human Interface Device) mouse. It was supposed to just work .
Navigating to ~/Library/Preferences/ , she found the file: com.apple.Bluetooth.plist . Her heart pounded as she dragged it to the trash. She shut down the Mac—not restart, a full shutdown. She counted to thirty. She powered on.
