Keyboard responsive in one app but not others?

Fix #1: Check Keyboard Language/Input

Success Rate: 10% • Time: 2 minutes

Step 1: System Settings → Keyboard → Input Sources
Step 2: Make sure correct input language is selected
Step 3: Sometimes wrong input (e.g., Dvorak) makes keys appear unresponsive
Step 4: Try switching to US English or your local language
Step 5: Test keyboard

Unlikely but worth checking.

Fix #2: Clean Under Keys

Success Rate: 60% • Time: 10 minutes

Step 1: Power off MacBook completely
Step 2: Close the lid
Step 3: Tilt MacBook at an angle (30-45 degrees)
Step 4: Use compressed air to blow out debris (3-5 second bursts)
Step 5: Focus on the unresponsive key area
Step 6: Don't hold upside down — tilt at an angle
Step 7: Power back on and test

Dust and debris under keys is the #1 cause of unresponsiveness.

Fix #3: Reset SMC

Success Rate: 35% • Time: 5 minutes

Intel MacBook:
1. Shut down completely
2. Press Shift + Control + Option (left side) + Power button
3. Hold 10 seconds
4. Release all keys
5. Wait 5 seconds, power on normally

Apple Silicon (M1/M2/M3):
1. Shut down
2. Press power button for 10 seconds, then release
3. Wait a few seconds
4. Press power to start

SMC controls keyboard hardware behavior. Reset can fix stuck keys.

Fix #4: Reset NVRAM/PRAM

Success Rate: 25% • Time: 3 minutes

Intel MacBook only (not Apple Silicon):
1. Shut down
2. Immediately power on
3. Hold Command + Option + P + R
4. Hold until you see the Apple logo twice
5. Release and let it boot normally

Apple Silicon: Automatic (no manual reset needed)

Clears keyboard settings. Worth trying if SMC reset didn't work.

Fix #5: Force Restart

Success Rate: 30% • Time: 2 minutes

Step 1: Save any open work
Step 2: Shut down: Apple menu → Shut Down
Step 3: Wait 30 seconds
Step 4: Power back on
Step 5: Test keyboard

Often clears temporary glitches that affect keyboard recognition.

Fix #6: Test in Safe Mode

Success Rate: 40% (diagnostic) • Time: 5 minutes

Intel MacBook:
1. Shut down
2. Power on and hold Shift until login screen
3. Login (Safe Mode restricts startup apps)
4. Test keyboard

Apple Silicon:
1. Power on and hold power button
2. Release when you see startup options
3. Select your drive, hold Shift and click "Continue"

If keyboard works in Safe Mode: third-party app is interfering. Check recent installs.

Usually: debris under that specific key
Solution: Use compressed air on that key area
If still stuck: key mechanism may be damaged (hardware issue)

Multiple Keys Unresponsive

Try all fixes above (especially SMC reset)
If persists: entire keyboard may be failing
Likely requires keyboard replacement

Keys Respond but Produce Wrong Characters

Check input language (Fix #1)
Try different language/keyboard layout
Usually software, not hardware

Entire keyboard dead (no keys respond)
