How to Fix or Disable Magic Mouse Zooming By Itself Randomly

Apple’s wireless Magic Mouse for desktop Macs is a truly revolutionary computer mouse. For a more premium feel to the whole experience and for increased ease of use, everything on the Magic Mouse – from clicking to scrolling – happens via touch. The entire surface of the Magic Mouse is touch-sensitive, which basically makes the Magic Mouse a trackpad that offers the same look and feel of a mouse. The Magic Mouse has a scroll-zooming feature which allows users to zoom in and out of their displays by simply touch-scrolling.

In most areas, the Magic Mouse’s scroll-zooming feature is a godsend. However, in a few areas, such as when interactive maps are on the user’s screen or when using an Adobe application, even the slightest bit of movement on the Magic Mouse’s surface can be registered as a scroll-zoom, uncontrollably zooming in and out of the display. Your entire display being zoomed in and out uncontrollably when you simply move your mouse around or drag and drop objects on your screen can be pretty frustrating, to the extent where it becomes almost motion sickness-inducing.


Thankfully, though, the following are some of the most effective solutions that can be used to disable the Magic Mouse’s scroll-zoom feature and/or get rid of it:

Solution 1: Disable the scroll-zooming feature

  1. Go to System Preferences > Universal Access > Seeing.
  2. Click on Options… in the Zoom
  3. Uncheck and disable the Zoom using scroll wheel while holding
  4. Save the changes that you have made.

Solution 2: Disable the Smart Zoom feature

  1. Go to System Preferences > Mouse.
  2. Locate and uncheck the Smart Zoom option under the Point & Click section to disable
  3. Save the changes.

Solution 3: Get another mouse and use it to interact with problem areas

If neither of the two solutions described above worked for you, your only remaining course of action is to acquire another mouse (preferably a wired one with physical buttons and a physical scroll wheel) and use it to interact with areas and applications in which the Magic Mouse causes uncontrollable and significant scroll-zooming. You can choose to plug the other mouse into your computer only when you need it, but you could also just leave it connected all the time and safely tucked away so that, when you need it, all you need to do is set the Magic Mouse aside and use your other mouse. Thankfully, because your computer is a Mac, leaving the Magic Mouse and the other mouse connected to it at all times won’t cause any kind of clash between them and both of them will work exactly as they are supposed to.
