You’re sitting there, deadline looming, and suddenly the cursor just... stops. It’s frozen. You click, you tap, you perform that frantic two-finger scroll, but nothing happens. It’s a specific kind of panic. When the touchpad on MacBook Air not working becomes your reality, it feels like the entire machine is suddenly a very expensive paperweight. Honestly, we’ve all been there. Most people assume the hardware is fried, but usually, it's something much weirder or, thankfully, much simpler.
MacBook trackpads are marvels of engineering. Unlike old laptops with physical diving-board buttons, modern MacBook Airs use Force Touch. There isn't actually a button under there. Your brain thinks there is because of a haptic engine called the Taptic Engine that "clicks" back at you. If that engine loses power or gets a software glitch, the trackpad feels "dead" or stuck, even if the glass itself is fine.
First, Check the Silly Stuff
Before you go booking a Genius Bar appointment or crying over your bank balance, let's look at the obvious. I know, I know—you're smart. But you’d be surprised how many times a touchpad on MacBook Air not working is just a setting you forgot about.
Check for a wireless mouse. Seriously. If you have a Magic Mouse or a Bluetooth trackpad buried in your backpack or sitting in another room, and it’s "on," your MacBook might be disabling the built-in trackpad to prioritize the external one. It’s a feature, not a bug, technically. Go to System Settings > Accessibility > Pointer Control and see if "Ignore built-in trackpad when mouse or wireless trackpad is present" is toggled on. If it is, and your mouse is clicked "on" inside your bag, your trackpad will stay dead until you move that mouse.
The Software Ghosts in the Machine
Sometimes the software that talks to the hardware just... quits. It’s like a waiter forgetting a table exists. You can try to "force" the macOS to remember the trackpad is there by resetting the SMC (System Management Controller) or the NVRAM/PRAM.
Now, if you have an M1, M2, or M3 MacBook Air (Apple Silicon), the process is different. These chips don't really have a traditional SMC. Usually, just shutting the lid for 30 seconds and reopening it, or a full restart, does the trick. But for those still rocking the Intel-based MacBook Airs, an SMC reset is the "holy grail" of fixes. You shut down, hold Shift-Control-Option and the Power button for 10 seconds, and let go. It resets the power flow to components like the trackpad.
Why Your Touchpad on MacBook Air Not Working Might Be a Battery Issue
This is the one that scares people, and for good reason. Underneath that glass trackpad sits the lithium-ion battery. These batteries are designed to be thin and flat. However, as they age or if they're exposed to extreme heat, they can undergo a chemical reaction that causes them to swell.
It starts subtly.
Maybe the trackpad feels harder to click than usual. Maybe it feels "stiff." Eventually, the battery expands so much it physically pushes against the underside of the trackpad. If your trackpad is physically bulging or if the laptop doesn't sit flat on a table anymore, stop using it immediately. A swollen battery is a fire hazard. Apple’s own support documentation and various repair experts at iFixit have documented this for years. If the battery is the culprit, the fix isn't a software patch—it's a hardware replacement.
Dust, Gunk, and the Friction Problem
We eat over our laptops. We drink coffee. Skin oils, crumbs, and microscopic debris find their way into the tiny perimeter gap around the trackpad.
If a tiny crumb gets wedged in that gap, it can trick the Force Touch sensors into thinking you're constantly pressing down. Or, it can block the haptic feedback entirely. Grab a soft-bristled toothbrush or a can of compressed air. Gently—emphasis on gently—clean that seam. You might find that a single grain of salt was the reason your touchpad on MacBook Air not working was driving you crazy.
The "Haptic Feedback" Settings
Sometimes the trackpad is "working" but it doesn't feel like it. Since there's no moving part, the "click" is simulated. If your "Click" pressure is set to "Firm" in System Settings, you might feel like you're pushing against a brick.

Go to System Settings > Trackpad.
- Check the "Click" slider.
- Slide it to "Light."
- Toggle "Silent clicking" off and on.
Sometimes toggling these settings forces the Taptic Engine to recalibrate. It’s a quick digital nudge that often brings the hardware back to life.
Troubleshooting the T2 Security Chip
If you have an Intel Mac from roughly 2018 to 2020, you have the T2 Security Chip. This chip handles a lot of things, including the touch bar (if you have a Pro) and some input/output functions. Occasionally, the bridgeOS—the software that runs on the T2 chip—crashes.
When this happens, you might find your keyboard works but your trackpad is dead. The only real way to fix a "hung" T2 chip is a hard restart or, in extreme cases, using another Mac to "Revive" or "Restore" the firmware using Apple Configurator. It sounds intimidating because it is. Most casual users shouldn't do this unless they've exhausted every other option, but it's a known fix in the technician world.
Humidity and Static
It sounds like voodoo, but it's physics. Trackpads are capacitive. They rely on the electrical conductivity of your finger. If the humidity is extremely high, or if there's a weird static buildup on the chassis of the MacBook Air, the sensors get confused.

Try this: touch a grounded metal object to discharge any static you're carrying. Then, take a slightly damp (not wet!) microfiber cloth and wipe the trackpad surface thoroughly. Dry it immediately. Sometimes a layer of oil or moisture creates a "ghost touch" effect where the cursor jumps around or refuses to move.
Updating macOS: Not Just for New Emojis
Apple frequently pushes "HID" (Human Interface Device) updates within their macOS releases. If you’re running an ancient version of Big Sur or Monterey on a newer machine, you might be missing critical driver patches.
If you can plug in a USB mouse, go to System Settings > General > Software Update. Even a minor "point" update (like 14.1 to 14.2) can contain firmware fixes for the trackpad controller. It’s the least invasive fix, so it’s always worth checking before you start unscrewing the bottom plate.
When to Give Up and Go to the Pro
If you’ve reset the SMC, cleaned the edges, toggled the settings, and your touchpad on MacBook Air not working persists, it’s likely a hardware failure.
Trackpads connect to the logic board via a very thin, very fragile ribbon cable. This cable runs directly over the battery. If you’ve ever spilled a tiny amount of liquid—even a drop—it often runs down through the keyboard and lands right on that connector. Corrosion happens fast. A technician can usually tell within five minutes if there’s liquid damage by looking at the internal LCI (Liquid Contact Indicators).
Practical Next Steps for a Broken Trackpad
Don't panic. Start with the software and work your way out.
- Plugin a Mouse: Use any cheap USB or Bluetooth mouse to regain control. This allows you to navigate the menus needed for testing.
- Safe Mode: Restart your Mac and hold the Power button (Silicon) or Shift (Intel) to enter Safe Mode. This disables third-party drivers. If the trackpad works in Safe Mode, you have a software conflict—usually a weird utility app or an old driver.
- Check for Swelling: Lay the laptop on a perfectly flat glass surface. If it wobbles, your battery is likely swelling and pressing on the trackpad.
- The "D" Key Test: Restart and hold the D key to enter Apple Diagnostics. It will run a hardware scan. If it spits out a code like NDR001, NDR003, or NDR004, your trackpad is officially a hardware goner.
- External Repair: If you’re out of warranty, third-party shops are often half the price of Apple for a trackpad replacement. It’s a modular part, meaning they don’t have to replace the whole top case (usually), which saves you a ton of money.
The reality of a touchpad on MacBook Air not working is that it's rarely a mystery for long. It’s almost always a settings mishap, a dirty sensor, or a battery that’s lived its best life. By systematically ruling out the easy stuff—like that hidden mouse in your bag or a dirty seam—you can save yourself a trip to the store and a lot of frustration.
