Your MacBook trackpad not working properly? Before you panic, let's diagnose whether it's a simple software glitch or something more serious.

Software Troubleshooting

Quick Tests First

• Does the trackpad work in Recovery Mode? (Restart, hold Command + R)
• Does it work with a new user account?
• Does it work in Safe Mode? (Restart, hold Shift)

SMC Reset (Intel Macs)

1. Shut down completely
2. Press Shift + Control + Option + Power for 10 seconds
3. Release and power on normally

Check System Settings

• System Settings → Trackpad → Check all options
• Ensure "Tap to click" is enabled if you prefer that
• Check tracking speed isn't set extremely slow

Common Hardware Causes

The Battery Swelling Problem

Warning

Safety alert: If your trackpad is raised or won't click properly, check if the battery is swelling. A bulging battery case or difficulty closing the lid are warning signs. Stop using the Mac and get it checked immediately - swollen batteries can be dangerous.

Battery swelling is the #1 cause of trackpad click failure. As the battery expands, it pushes up against the trackpad from below, preventing the click mechanism from working. If this is your issue, you'll need a battery replacement.

Signs of Battery Swelling

• Trackpad sits higher than normal or feels raised
• Physical click doesn't work (but tap-to-click does)
• Bottom case looks slightly bulged
• Mac wobbles on flat surface
• Lid doesn't close flush

Flex Cable Issues

The trackpad connects to the logic board via a thin flex cable. On MacBook Pros from 2016-2019, these cables run near the display hinge and can fail over time—similar to the keyboard flex cable issues on the same models.

Symptoms of Cable Issues

• Trackpad works intermittently
• Cursor jumps or behaves erratically
• Works better when lid is at certain angles
• Issue appeared gradually over time

The good news: cable replacement is relatively straightforward and much cheaper than trackpad replacement.

Trackpad Replacement Process

1. Diagnosis: We verify the issue (trackpad vs cable vs battery)
2. Quote: Exact price based on model and issue
3. Battery check: If swelling, we'll replace that too
4. Replacement: New trackpad with Force Touch calibration
5. Testing: All gestures, pressure levels, and click verified

Frequently Asked Questions

Can I use a mouse while the trackpad is broken?

Yes, any USB or Bluetooth mouse works fine. You can also enable "Tap to Click" in System Settings if physical clicks don't work but touch tracking does.

Why does Apple replace the whole top case?

Apple's repair approach bundles keyboard, trackpad, and battery into one "top case" assembly. We use component-level repair techniques to fix just the faulty part, saving you significant cost.

Is a swollen battery dangerous?

It can be. While most swell slowly and safely, punctured or crushed lithium batteries can catch fire. Don't use excessive force on a swollen Mac, and get it serviced promptly.
