Custom MouseTap to click, right-click and real pinch-to-zoom for your Apple Magic Mouse.

Short answer: macOS has no tap-to-click setting for the Magic Mouse. Tap to click exists only in the Trackpad settings. On a Magic Mouse every click is a physical press of the whole shell — which is why so many people find its click stiff, loud or tiring after a long day.

To make a Magic Mouse click with a light tap:

1. Install Custom Mouse and open it from the menu bar.
2. Allow it in System Settings → Privacy & Security → Accessibility (the app shows you where).
3. Tap lightly toward the front of the mouse, on the left half (by default the front 60% of the left side responds; the settings window highlights the exact area). That tap is now a click; tap twice for a double-click, three times for a triple-click.

Pressing still works exactly as before, so you can mix taps and presses. If taps fire when you only meant to rest your hand, lower the sensitivity in the settings window.

There are three ways to right-click (secondary click) with a Magic Mouse on a Mac:

1. Turn on Secondary click. Open System Settings → Mouse and set Secondary click to Click Right Side. Then press down on the right half of the mouse.
2. Control-click. Hold the Control key and click anywhere. Works everywhere, but needs two hands.
3. Tap the right side with Custom Mouse — a real right-click with no press and no modifier key. Turn on Right-side tap for right-click in its settings window first (it’s off by default).

Magic Mouse right-click not working?

• Secondary click is off. Check the setting above; it is sometimes reset after pairing a new mouse.
• Another finger is touching the left side. The Magic Mouse reports a left click whenever a finger rests on the left half. Lift it, press only on the right.
• It right-clicks when you don’t want it to. Your finger is drifting onto the right side. Move it left, or set Secondary click to the opposite side. Custom Mouse’s settings window draws the exact zones.
• Low battery or a weak Bluetooth link can drop clicks. Charge the mouse and re-pair it if needed.

The Magic Mouse cannot pinch to zoom on its own. macOS gives it two partial substitutes:

• Smart zoom — double-tap with one finger to zoom a webpage or PDF in, and again to zoom back out. Turn it on in System Settings → Mouse. It toggles between two fixed levels; it can’t zoom gradually. If you use Custom Mouse’s double-tap, leave it off (see Recommended settings below).
• Accessibility zoom — in System Settings → Accessibility → Zoom, turn on Use scroll gesture with modifier keys to zoom, then hold Control and scroll. This magnifies the whole screen, not the document you’re looking at.

Neither is the pinch you know from a trackpad or an iPhone. Custom Mouse adds a real two-finger pinch to zoom: spread two fingers on the mouse to zoom in, bring them together to zoom out. It sends the same magnify gesture a Magic Trackpad sends, so it works smoothly and continuously in apps that support trackpad pinch — not a ⌘+scroll or keyboard-shortcut imitation.

A good starting point in System Settings → Mouse:

• Tracking speed — one or two notches above the default if you have a large or high-resolution display.
• Natural scrolling — on if you also use an iPhone or iPad; off if you’re used to a wheel mouse.
• Secondary click — Click Right Side, so pressing the right half still right-clicks.
• Swipe between pages and Swipe between full-screen apps — on; they don’t interfere with Custom Mouse.
• Smart zoom — off. It also reacts to a one-finger double-tap, so with it on, a double-tap in Safari or a PDF would double-click and zoom the page.

Then in Custom Mouse: leave tap sensitivity at the default for a day, and lower it only if you notice accidental clicks while resting your hand.
