This is the second apple mouse I have bought for my Mac. The problem with both of them is they will not scroll down, just up using the little scrolling button on top. What gives?
Thanks for any help you might offer. The old one was wireless this newer one is USB – I disconnected it and plugged it back in but nothing helped.
This is actually a dirty scroll ball issue. There is not a problem with your computer or the mouse hardware. You just need to clean the dirt out of the scroll sensor. This is so common that Apple made a demo video on how best to clean your mouse.
