After a macOS replace, a MacEbook can attain the login display screen or desktop whereas its built-in keyboard and trackpad ignore each keypress, click on, and gesture. The energy or Touch ID button should work, however the pointer stays nonetheless and the trackpad could lose its regular haptic click on.

The Mac exhibits no error explaining what stopped. The timing makes the replace look accountable, nevertheless it doesn’t show that macOS broken the enter units.

An replace can expose an incompatible enter utility or broken system element. An accessibility setting, unapproved exterior gadget, or {hardware} shared by the keyboard and trackpad can produce the identical outcome.

The most helpful clue is the place enter returns. A Mac that works on the login display screen, in Safe Mode, or in Recovery wants a distinct restore from one whose built-in controls stay lifeless in each startup atmosphere.

What nonetheless responds	What that outcome tells you
Built-in enter works at login, then stops on the desktop	A login merchandise, extension, remapper, or account setting is loading after sign-in.
Built-in enter works solely in Safe Mode	Software excluded by Safe Mode is interfering with regular startup.
Built-in enter works in Recovery however not in macOS	The {hardware} can nonetheless talk exterior the put in working system.
Only an exterior keyboard or mouse works	Use it to full the software program assessments, however don’t rule out shared inner {hardware}.
Built-in enter fails in Recovery and Apple Diagnostics	Further reinstalls are unlikely to assist; report the outcome for {hardware} service.

1. Check the Mac With a Known-Good External Keyboard or Mouse

Built-in enter can fail when the Mac is ready behind an unseen low-battery alert or when its inner controls cease speaking. A working exterior gadget bypasses these controls and separates a locked session from a whole-Mac enter failure.

Use this solely with a tool you already know works, linked instantly. An untested dock, hub, cable, and keyboard collectively introduce too many unknowns. Skip this check if the liquid or swelling warning above applies.

1. Connect the Mac instantly to energy and depart it linked whilst you check.
   
2. Connect a known-good wired USB keyboard or mouse instantly to the Mac. Try one other port if the primary one doesn’t reply.
3. On a Mac laptop computer with Apple silicon, a brand new USB gadget could present Unlock to use equipment. A locked Mac have to be unlocked earlier than it may well approve an unknown USB or Thunderbolt accent.
4. For a Magic Keyboard or Magic Trackpad, flip it off and on. Connect it with its charging cable for about one minute, then observe Apple’s Magic accent pairing methodology.
   

   

5. If an Apple-silicon Mac rejects new wired enter whereas locked, shut it down. Hold the ability button till startup choices seem.
6. Press the ability button 3 times, with every press inside one second of the earlier press. Use Bluetooth Setup Assistant to pair a keyboard, mouse, or trackpad.
7. Restart as soon as. If the Mac won’t restart usually, maintain the ability or Touch ID button for up to 10 seconds, then flip it on once more. A pressured shutdown can discard unsaved work.

If the built-in controls return after energy or restart, the failure was momentary. If solely the exterior gadget works, preserve it linked and proceed under; it’s now the management you want for the remaining assessments.

2. Check the Settings That Can Suppress Keyboard or Trackpad Input

Typing fails when Mouse Keys takes over the keyboard. Slow Keys delays every keystroke, whereas Pointer Control can ignore the built-in trackpad when Mouse Keys or one other pointing gadget is lively.

Use this solely when these accessibility options weren’t enabled deliberately. Otherwise, alter their choices relatively than turning them off.

1. Using the working exterior gadget, open Apple menu > System Settings > Accessibility > Pointer Control.
2. Turn off Mouse Keys. You may also press Option-Command-F5 and deselect it in Accessibility Shortcuts.
   

   

3. Clear Ignore built-in trackpad when mouse or wi-fi trackpad is current. Open the Mouse Keys info button and additionally clear Ignore built-in trackpad when Mouse Keys is on.
4. Open Accessibility > Keyboard and flip off Slow Keys. Apple contains Mouse Keys and Slow Keys in its official unresponsive-keyboard checks.
5. If Mouse Keys was enabled unintentionally, open its choices and flip off Press the Option key 5 occasions to toggle Mouse Keys.
   

   

If keyboard enter or trackpad motion returns, no operating-system restore is required.

For typing alone, use the narrower MacEbook keyboard checks. For scrolling or gestures alone, use the trackpad scrolling checks.

If each built-in units are nonetheless unresponsive, proceed under.

3. Test the Login Session and Safe Mode

Input that works earlier than sign-in and dies solely when the desktop opens is robust proof in opposition to a totally disconnected keyboard or trackpad. macOS could also be loading a remapper, driver, safety extension, or login merchandise that now not agrees with the up to date system.

Safe Mode helps as a result of it excludes a lot of that startup software program. Do not use the elimination steps on a managed work or faculty Mac; report the outcome and depart managed instruments for the administrator.

1. If the controls work at login, enter the password and click on Log In. Immediately maintain left Shift till the desktop seems. Apple paperwork this below its different Mac startup strategies.
2. Test the built-in keyboard and trackpad earlier than opening any app. If they now work, take away the just lately added merchandise below System Settings > General > Login Items & Extensions.
3. On Apple silicon, shut down and maintain the ability button till startup choices seem. Select the startup disk, maintain Shift, and click on Continue in Safe Mode.
4. On an Intel Mac, flip it on and instantly maintain Shift till the login window seems. Apple’s Safe Mode information covers each startup procedures.
   
5. Test the built-in controls earlier than opening different apps. If they work, set up any pending macOS replace, then assessment Login Items & Extensions for just lately added enter remappers, mouse utilities, safety instruments, and driver extensions.
   

   

6. Restart usually and restore disabled gadgets separately. Update or take away the merchandise that makes each built-in units cease responding once more.

If enter works after a standard restart, the replace uncovered a startup-software battle relatively than an inner {hardware} failure. If Safe Mode continues to be unresponsive, proceed under and check the controls exterior the put in copy of macOS.

4. Use macOS Recovery to Separate macOS From the Built-In Hardware

Normal enter fails when broken macOS parts or low-level software program intervene after startup. Recovery runs independently of that session, so working enter there confirms that the Mac can nonetheless obtain keyboard and trackpad alerts exterior the put in system.

Do not use Erase for this check. Keep a working exterior enter gadget hooked up if the built-in controls are wanted just for comparability.

1. On Apple silicon, shut down the Mac, maintain the ability button till startup choices seem, choose Options, and click on Continue.
2. On an Intel Mac, flip it on and instantly maintain Command-R. Use a wired keyboard if a wi-fi startup shortcut doesn’t register. Apple paperwork each paths in its macOS Recovery directions.
3. Before opening one other utility, check the built-in keyboard and trackpad in Recovery.
   
4. If each units work in Recovery however stay lifeless in macOS, again up the Mac and select Reinstall macOS. A typical Recovery reinstall retains apps and private knowledge.
5. Allow the set up to end with out closing the lid, then check the built-in controls earlier than reinstalling enter utilities or restoring disabled extensions.

If the reinstall restores enter, the put in macOS state was accountable. If the built-in controls nonetheless fail in Recovery, cease repeating software program repairs and proceed under with Apple Diagnostics.

5. Use Apple Diagnostics and Record the Result for Service

When each built-in units fail in regular macOS, Safe Mode, and Recovery, shared inner {hardware} turns into extra probably. The timing of the replace doesn’t outweigh that proof.

Apple Diagnostics can establish some faults and supplies reference codes that make a service request extra helpful.

A clear outcome doesn’t show that an intermittent cable, sensor, trackpad controller, or logic-board connection is wholesome. Do not use it as permission to preserve working a swollen or liquid-damaged Mac, and don’t open the Mac solely as a result of no code seems.

1. Disconnect nonessential equipment, leaving energy and any keyboard, mouse, show, or Ethernet connection wanted for the check.
2. On Apple silicon, maintain the ability button till startup choices seem, then maintain Command-D.
3. On an Intel Mac, flip it on and instantly maintain D. Try Option-D if the primary shortcut doesn’t work.
4. Follow Apple’s Diagnostics directions. On macOS Tahoe 26 or later, choose the built-in keyboard and trackpad assessments when provided; earlier variations select the obtainable assessments robotically.
   

   

5. Keep each reference code and give it to Apple Support or an Apple Authorized Service Provider.

A Diagnostics code belongs within the restore request. Service can be applicable when the built-in controls stay lifeless in Recovery, or the failure adopted liquid, affect, case swelling, or inner restore.

If Diagnostics studies a code, embody it within the restore request. If no code seems however enter continues to be lifeless in Recovery, one other macOS reinstall is unlikely to add helpful info.
