I have an Apple mouse that has one button but it senses whether your finger is on the left or right side when you click. The scroll wheel also is "touchscreen". When I'm playing Minecraft, it will randomly scroll through my hot bar because of this. Is there a way to fix this or should i just buy a new mouse?
I used to use the same mouse. If you are careful, it will not randomly scroll through. The scroll wheel is one way people select items, and because the mouse broadcasts smooth motion rather than clicks for scrolling, your game will interpret it as a huge amount of scroll clicks, and will appear to be randomly shifting through items. If you keep your pointer finger on the mouse, it shouldn't scroll like that. I was able to play the game fine with the mouse. If it really bothers you, I would recommend getting a mouse with actual individual buttons and a click scroll wheel.
