magic mouse doesn't scroll in finder windows

I've got the same issue... scrolling in finder doens't work...

Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Preferences/com.apple.driver.AppleHIDMouse.plist. Move the .plist to your desktop.

Log out/in and test. If it works okay, delete the plist(s) from the desktop.

If the same, return the .plist(s) to where you got them from, overwriting the newer ones.

Thanks to leonie for some information contained in this.

You might need to redo the View settings after an update.

That works, thank you very much!

You are welcome.

You are welocme.

Worked! Many thanks!

go into your settings and click on bluetooth.

disconnect your mouse

try the finder now; it should work – it worked for me

reconnect your mouse, it should still work

Thanks, this work for me.

But i need to do it from the terminal. I can't find the 'Show Library Folder’.

You are welcome. In Finder hold down the option/alt key while selecting the Go menu item. Select Library.

Easiest solution: click on the finder icon in the dock and select "relaunch."

This works for me every time.

I think you have to hold the alt button when you click on the icon. There's an excellent demonstration on You Tube

scrolling like mad now! thank you.

This worked, thanks
