Fix MacBook Keyboard Not Working: 10+ Proven Solutions (2024 Guide)
TL;DR: If your MacBook keyboard isn’t working, start by restarting your Mac and checking for software updates. For persistent issues, try resetting NVRAM or SMC, cleaning the keyboard, or connecting an external keyboard to troubleshoot. If hardware failure is suspected (common in 2016–2019 Butterfly keyboards), contact Apple Support or visit an authorized service center.
I’ve been there—suddenly, my MacBook’s keyboard stops responding right when I need it most. Whether it’s a single key, the entire keyboard, or intermittent glitches, a non-functional keyboard can bring your workflow to a halt. Based on Apple Support guidelines, user forums, and my own experience, I’ve compiled a comprehensive guide to diagnose and fix a MacBook keyboard that’s not working. Let’s dive in.
Why Is My MacBook Keyboard Not Working?
Before jumping into fixes, it’s helpful to understand why your keyboard might fail. Common causes include:
- Software glitches or macOS bugs
- Incorrect keyboard settings or layout
- Low battery or power issues
- Dirt, debris, or liquid damage
- Hardware failure (especially in older Butterfly mechanism keyboards)
- Bluetooth connectivity problems (for external keyboards)
Step-by-Step Fixes for MacBook Keyboard Not Responding
1. Restart Your MacBook
Often, a simple restart can resolve temporary software glitches. Shut down your Mac completely (not just sleep or log out), wait 30 seconds, and turn it back on. During restart, uncheck "Reopen windows when logging back in" to ensure a clean boot^9.
2. Check Keyboard Settings and Layout
Sometimes, the keyboard might seem unresponsive due to incorrect settings. Here’s how to verify:
- Go to System Settings > Keyboard > Text Input.
- Click Edit and ensure "Show Input menu in menu bar" is turned on.
- Open the Input menu from the top bar and confirm the correct keyboard layout is selected (e.g., U.S. or your region’s layout)^1.
- Also, disable Mouse Keys (under System Settings > Accessibility > Pointer Control) as it can interfere with keyboard input^3.
3. Connect an External Keyboard
If the built-in keyboard is completely dead, connect a USB or Bluetooth external keyboard. This helps determine if the issue is hardware or software-related. If the external keyboard works, your built-in keyboard might need cleaning or repair^5.
4. Clean Your Keyboard
Dirt, crumbs, or debris can cause keys to stick or fail. Gently clean between keys using compressed air or a soft brush. For stubborn grime, use a slightly damp lint-free cloth. Avoid liquid cleaners or excessive moisture^6.
5. Reset NVRAM/PRAM
NVRAM (Non-Volatile Random-Access Memory) stores settings like keyboard brightness and volume. Resetting it can fix input issues:
- Shut down your Mac.
- Press the power button, then immediately hold Command + Option + P + R.
- Keep holding until you hear the startup chime twice (or see the Apple logo twice on newer Macs).
- Release the keys and let your Mac boot normally^7.
6. Reset SMC (System Management Controller)
The SMC controls hardware functions, including keyboards. Reset steps vary by Mac model:
- For MacBooks with T2 chip or Apple Silicon (M1/M2): Shut down, wait 10 seconds, then turn on.
- For older MacBooks with removable battery: Shut down, remove battery, hold power button for 5 seconds, reinsert battery, and turn on.
- For newer MacBooks without removable battery: Shut down, press Shift + Control + Option + Power button simultaneously for 10 seconds, then release and power on^6.
7. Run Apple Diagnostics
Apple Diagnostics can identify hardware issues:
- Shut down your Mac.
- Turn it on and immediately press and hold the D key.
- Follow on-screen instructions to complete the test. If keyboard issues are detected, it will recommend repairs^2.
8. Update macOS
Outdated software can cause compatibility problems. Go to System Settings > Software Update and install any available updates. Restart your Mac afterward^6.
9. Check for Third-Party App Conflicts
Recently installed apps might interfere with keyboard functionality. Boot into Safe Mode to check:
- Shut down your Mac.
- Press the power button, then immediately hold Shift until you see the login window.
- Log in and test the keyboard. If it works in Safe Mode, uninstall recent apps or reset permissions.
10. Erase and Reinstall macOS (Last Resort)
If all else fails, a clean macOS install can resolve deep-seated software issues. Back up your data first, then use macOS Recovery (hold Command + R during startup) to erase and reinstall. Note: This will delete all data, so use it only if necessary^3.
Common Mistakes to Avoid
- Using harsh cleaners: Avoid alcohol or abrasive materials that can damage keys.
- Skipping backups: Always back up data before attempting resets or reinstalls.
- Ignoring battery alerts: A low battery can cause unresponsiveness; plug in your MacBook^1.
- Overlooking Bluetooth settings: For external keyboards, ensure Bluetooth is on and the keyboard is paired correctly^1.
Case Study: M2 MacBook Air Keyboard Fix
A user on Apple Discussions reported their new M2 MacBook Air keyboard stopped working suddenly. After trying resets and diagnostics without success, they erased and reinstalled macOS. The keyboard started working again, likely due to a software glitch related to voice dictation settings. This highlights that even new models can face issues solvable with a clean install^3.

Can I use an external keyboard if my MacBook keyboard isn’t working?
Yes, connect a USB or Bluetooth keyboard to access your Mac and troubleshoot. This helps isolate whether the problem is hardware or software.
Is cleaning the keyboard safe?
Yes, use compressed air or a soft, dry cloth. Avoid liquids or harsh cleaners to prevent damage.
Why do some keys work but others don’t?
This often indicates dirt under specific keys or localized hardware damage. Try cleaning first; if unresolved, it may need repair.

Step-by-Step: How to Run Apple Diagnostics
I’ve found that running Apple Diagnostics can quickly pinpoint hardware issues without needing to log in. Here’s how I do it:
- Shut down the MacBook completely.
- Press the power button, then immediately hold the D key until the diagnostics screen appears.
- Wait for the test to complete—it usually takes a few minutes and will flag any hardware failures, including keyboard or trackpad issues^2.
Pros and Cons of Using an External Keyboard
Using an external keyboard is my go-to temporary fix, but it has its trade-offs:
- Pros: Immediate access to the Mac, helps isolate whether the issue is software or hardware, and allows continued use while troubleshooting^5.
- Cons: Not portable, adds clutter, and doesn’t resolve the underlying problem with the built-in keyboard.
Comparison: NVRAM vs. SMC Reset
I often get asked about the difference between these resets, so here’s a quick breakdown based on my experience:
- NVRAM Reset: Clears settings like volume, display resolution, and startup disk selection. I use it when keys behave unexpectedly or system preferences seem off. Hold Command+Option+P+R at startup until you hear the second chime^7.
- SMC Reset: Addresses power-related issues, including unresponsive keyboards, backlight problems, or fans running at high speed. The steps vary by model: for MacBooks with T2 chip or Apple Silicon, I just shut down and restart; for older models, it’s Shift+Control+Option+power button^6.
Why Keyboard Layout Settings Matter
Sometimes, the issue isn’t hardware—it’s software. I’ve had moments where my keyboard seemed broken, but it was just set to the wrong layout. To check:
- Go to System Settings > Keyboard.
- Click "Edit" next to Input Sources.
- Ensure the correct layout (e.g., U.S. English) is selected and enabled^1. If it’s off, keys might type unexpected characters or not respond at all.
When to Consider a Full Wipe
As a last resort, I’ve seen cases—like one user on Apple Discussions—where a factory reset resolved persistent keyboard glitches, possibly due to corrupted software or voice control settings interfering^3. Before doing this, I always back up data with Time Machine or an external drive. It’s drastic, but it can save a trip to the repair shop.
