Why can't I use the laptop's built-in trackpad?

One possible reason for a malfunctioning trackpad is a pointer setting in System Preferences. Follow these steps to make sure you have the right setting: 

1. Open System Preferences > Accessibility. 
2. Select Pointer Control. 
3. Select the Scroll & Zoom tab.
4. Make sure Ignore built-in trackpad when mouse or wireless trackpad is present checkbox is is empty. If you leave the checkbox marked while a mouse is still connected to your laptop, you won't be able to use the trackpad. 
   
   

How do I customize the trackpad's click settings?

You can change how the trackpad behaves in System Preferences > Trackpad > Point & Click so you can use the app just the way you want.

• Secondary click 
  Choose one of the three different methods for triggering a secondary click with the trackpad: "Click or tap with two fingers," "Click in bottom right corner," and "Click in bottom left corner."
• Tap to click 
  Mark this checkbox so you can tap the trackpad with one finger to click. You don't have to press down on the trackpad anymore. 
• Click 
  Specify how firmly you have to press the trackpad to click: light, medium, or firm. If you mark the Tap to click checkbox, though, this setting is irrelevant. 
• Tracking speed 
  Adjust how fast the pointer should follow your finger on the trackpad. 

How do I zoom to face if the trackpad won’t recognize double taps as double clicks?

Even if you enable the Tap to click setting for your trackpad, it won't be able to register double taps as double clicks when the Smart zoom feature is also enabled. You can fix this conflict in a few steps:

1. Open System Preferences > Trackpad. 
2. Select the Scroll & Zoom tab.
3. Unmark the Smart zoom checkbox.

Why can't I rotate the camera with the Magic Mouse? 

There are a few ways you can rotate the view in the app with the Magic Mouse:

• Hold down the Shift key, secondary click (or right-click), and drag the mouse
• Hold down the Shift key and pan with two fingers or one finger on the Magic Mouse

If you have Swipe between full-screen apps enabled in System Preferences > Mouse > More Gestures,  you might encounter problems when you pan with two fingers on the Magic Mouse — without pressing the Shift key first. 

If you prefer to keep Swipe between full-screen apps enabled, then you can try the other shortcuts: 

• Hold down the Shift key, secondary click (or right-click), and drag the mouse
• Hold down the Shift key and pan with one finger on the Magic Mouse
