Nothing ruins a smooth workflow faster than pressing down on your MacBook trackpad only to realize the signature Force Touch click feels like a completely dead piece of glass.
In my eight years of tearing down laptops and diagnosing hardware bugs, I have seen hundreds of users panic when their trackpad stops clicking. The sudden loss of tactile feedback makes it feel as though the mechanical spring inside snapped.
Here is the secret most people do not realize: modern Mac trackpads do not have a physical button underneath. Apple switched to a solid-state glass design powered by electromagnetics and pressure sensors. When your click stops working, you are usually dealing with a software driver freeze, a power daemon crash, or an expanding battery pushing against the sensor board from inside the chassis.
Before booking an expensive service appointment, follow this diagnostic guide I developed on my repair bench to get your Force Touch haptics firing again.
Understanding the Taptic Engine Architecture
To fix the issue, you must understand what creates the click. Beneath the glass surface sits the Taptic Engine, an electromagnetic actuator that vibrates rapidly when force sensors detect downward pressure.
This creates the realistic illusion of a physical drop-click. If your MacBook is powered off entirely, the trackpad will not click at all because there is no electricity feeding the magnets.
If your laptop is turned on but the trackpad feels rigid, macOS has lost communication with the Human Interface Device framework. This happens when background services freeze or power delivery flags get scrambled inside the system controller.

Method 1: Resetting System Preferences and Haptic Profiles
Sometimes the internal preference plist file controlling trackpad feedback becomes corrupted after a system update or unexpected shutdown. Re-initializing the haptic profile forces macOS to re-write these configuration files.
Click the Apple menu () in the top-left corner and open System Settings.
Scroll down the sidebar and select Trackpad.
Toggle the Force Click and haptic feedback switch off, wait five seconds, and turn it back on.
Drag the Click pressure slider from its current position to Light, test the surface, and then move it back to Medium or Firm.
Testing this on my bench machine restored immediate haptic clicks in about two out of ten cases where the software preference daemon had simply stalled out.
Method 2: Force Restarting the macOS Human Interface Device Daemon
When the GUI settings fail to respond, jumping into the command line bypasses the user interface entirely. macOS runs a background process named hidd (Human Interface Device Daemon) that manages all trackpad, keyboard, and mouse inputs.
Restarting this process forces the operating system to reload the Force Touch kernel extensions instantly.
Press Command (⌘) + Spacebar to open Spotlight, type Terminal, and press Enter.
Type the following command exactly as shown:
sudo killall hidd
Press Enter and type your administrator password when prompted.
Your screen may flash briefly for a second as input drivers reload. Once the process restarts automatically, press down on the trackpad surface to see if haptic feedback has returned.
Method 3: System Controller Resets for Intel and Apple Silicon
If background software is not the culprit, low-level power management chips might be withholding current from the Taptic Engine magnets.
Resetting the SMC on Intel MacBooks
For Intel models with the T2 security chip:
Shut down your Mac completely.
Press and hold Control + Option (Alt) + Shift on the built-in keyboard for 7 seconds.
While keeping those keys held down, press and hold the Power button for another 7 seconds.
Release all keys, wait 5 seconds, and boot your Mac normally.
Power Cycling Apple Silicon (M1, M2, M3, M4)
Apple Silicon chips do not have a traditional SMC. Instead, hardware controllers reset every time the machine shuts down completely without power connected.
Click Apple menu () > Shut Down.
Close the lid completely and disconnect the MagSafe or USB-C charging cable.
Leave the Mac completely powered off for at least two minutes.
Reopen the lid and press the power button to boot up.
Method 4: Diagnosing Battery Swelling and Physical Sensor Lock
If software tweaks and controller resets fail, you must consider the hardware environment beneath the palm rest. In my physical hardware evaluations, a degrading lithium-ion battery is the most common hardware cause behind a dead Force Touch click.
As MacBook batteries age or suffer heat stress, they off-gas and swell up. Because the battery sit directly beneath the glass trackpad frame, even a millimeter of expansion exerts upward force on the strain-gauge sensors. This constant pressure tricks the system into thinking the trackpad is permanently being held down, blocking new click triggers.
The Flat-Surface Inspection Test
Place your MacBook on a perfectly flat glass or granite table.
Look at the trackpad edges closely: Is the glass sitting flush with the aluminum palm rest, or is one corner raised?
Check if the laptop wobbles when you type on the corner palm rests.
If you notice lifting or casing deformation, stop using the charger immediately. Check the
Frequently Asked Questions
Why does my trackpad feel completely stiff when my Mac is turned off?
Modern Mac trackpads use an electromagnetic Taptic Engine instead of a mechanical spring. Without active electrical power from a booted system, the glass surface cannot vibrate or simulate a physical click.
Can a spilled liquid ruin Force Touch without breaking cursor movement?
Yes. Liquid often seeps around the perimeter gasket, shorting out the delicate strain-gauge pressure sensors while leaving the optical cursor tracking layer functional.
Why does my trackpad click work in Safe Mode but not normal mode?
Safe Mode disables third-party kernel extensions and startup items. If Force Touch works in Safe Mode, a third-party app (like a custom window manager or mouse utility) is intercepting input drivers.
