MacOS mouse shortcuts are reset upon restart or shutdown
My custom mouse shortcuts reset after each restart or shutdown. I assign Mouse Button 5 to Mission Control and Mouse Button 4 to Application Windows.
I’ve tested various Bluetooth mice and don’t use any mouse software—such as Logitech Options or LinearMouse.
This issue appears to be specific to macOS 15.1, as I haven’t encountered it in the past 2 years of using macOS.
