How to middle click on a MacBook trackpad

Apple trackpads have no middle button and macOS has no setting that produces one. You have three realistic options: a keyboard equivalent that works in some apps, an external mouse, or a utility that turns a trackpad gesture into a real middle click.

Option 1: keyboard equivalents (free, app by app)

Many apps offer another route to the thing you'd middle click for:

These cover the common cases but not the long tail: CAD viewports, games, remote desktops, Linux VMs, and web apps that listen for the middle button directly.

Option 2: an external mouse

Any three-button or scroll-wheel mouse gives macOS a real middle button with no software. Press the wheel. This is the right answer at a desk and the wrong answer on a train.

Option 3: a real middle click from the trackpad

A small utility can watch the trackpad for a specific gesture and send a genuine middle-button event, so every app sees exactly what a mouse would have sent. The Mid Click does this with a three-finger tap or click:

  1. Download it, move it to Applications, open it. It appears in the menu bar.
  2. Grant Accessibility access when asked. This is why it's needed.
  3. Pick Tap or Click, and Three or Four fingers.
  4. Try it on the test pad in the window: it reports Left, Right or Middle for each click it receives.
Tap mode
Three fingers down and up within about 300 ms, without sliding. Fastest. Fingers must not be resting beforehand.
Click mode
Rest three fingers and press the trackpad. The left click becomes a middle click, and holding it gives you middle-drag, which 3D apps need.
Four fingers
Same as above with four, for people who already use three-finger gestures.

Gestures that can get in the way

macOS reserves some multi-finger gestures. Check these in System Settings → Trackpad if a tap isn't recognised:

Which should you use?

If you only ever want "open in new tab" in a browser, ⌘-click is enough and free. If you close tabs by pointing at them, work in 3D or CAD tools, use a Linux VM, or just miss the button, a gesture utility is the only thing that behaves like a real middle button everywhere.
