Mac Sound Not Working? Fix No Audio on MacBook Air, Pro, and iMac

If your Mac sound is not working, first test audio in a second app or website, check that the app itself is not muted, and confirm that macOS is sending sound to the output device you actually want to use. On current macOS versions, go to Apple menu > System Settings > Sound > Output, select your Mac's built-in speakers when you want internal audio, raise the output volume, and make sure Mute is off.

A Mac can also appear to have no sound when audio is routed to headphones, a Bluetooth device, a USB audio interface, a dock, or an external display. Apple therefore recommends disconnecting external audio devices before assuming that the internal speakers have failed. If the basic checks do not restore sound, update macOS, test in Safe Mode, and use Apple Diagnostics when a hardware issue is still suspected.

Part 1. Why Is My Mac Sound Not Working?

Before changing system settings, identify whether the problem affects one app, every sound source, only the built-in speakers, or only a connected device. That distinction usually tells you which layer to check first.

Identify the No-Sound Symptom First

Use the symptoms below to separate a media or app problem from an output-routing or hardware problem before you start troubleshooting.

Apple's current guidance also notes that if any app or website can play audio through the Mac's built-in speakers, those speakers are working. That makes a single silent app or file a different problem from a system-wide Mac no sound issue.

What "Mac Volume Not Working" Can Mean

Volume on a Mac has more than one control point, so a visible volume slider does not always tell you where the problem is.

Troubleshooting order: confirm the content can play, verify the active output, disconnect competing audio devices, then move to deeper system checks.

Part 2. How to Fix Mac Sound Not Working

Start with the checks that do not change system data or hardware settings. The first method follows Apple's current no-sound workflow and resolves the most common routing and mute problems without Terminal commands or legacy reset procedures.

Check App Volume, Sound Output, and External Devices

This method is the best first choice when a MacBook Air, MacBook Pro, iMac, or other Mac suddenly stops playing sound but otherwise works normally.

Step 1. Test a second sound source.

Play audio in another app or website. Check the volume or mute control inside the original app, browser tab, or media player. If another source plays through the built-in speakers, the Mac speakers are functioning and the problem is likely limited to the original app, page, or file.

Tip: Use Siri as a free speaker test: disconnect all external audio devices, then say "Hey Siri, how are you?" If Siri answers audibly through the built-in speakers, your Mac's speakers are working and the problem is elsewhere (app, output routing, or software).

Step 2. Check the Mac's system volume.

Open Control Center and raise the Sound slider. On current macOS versions, Control Center provides direct access to the Mac's sound level and connected output choices.

Step 3. Select the correct output device.

Go to Apple menu > System Settings > Sound > Output. If you want sound from the Mac itself, select the built-in speakers or the speaker entry named for your Mac model. Raise Output volume, make sure Mute is off, and keep the Balance control centered unless you intentionally changed it.

Step 4. Disconnect external audio routes.

Temporarily disconnect headphones, USB or Thunderbolt audio devices, docks, and external displays connected by USB or HDMI. Also disconnect Bluetooth headphones or speakers long enough to retest the built-in speakers. Apple specifically recommends removing external audio devices when internal speakers are silent.

Step 5. Test the sound again.

Play a known-good source through the built-in speakers. If sound returns after one accessory is removed, reconnect devices one at a time and select the intended output explicitly. If the built-in speakers remain silent, continue with the software-isolation checks below. Apple's current internal-speaker troubleshooting guidance follows this same app-volume, external-device, and output-setting sequence.

Restart, Update macOS, and Test in Safe Mode

If the output device is correct but your Mac still has no sound, the next goal is to clear a temporary software state and check whether startup-loaded software is contributing to the problem.

Step 1. Restart the Mac.

Save your work, choose Apple menu > Restart, and test the same known-good audio source again after login. A restart is a low-risk check and should come before deeper reset procedures.

Step 2. Install current compatible macOS updates.

Back up important data first, then go to Apple menu > System Settings > General > Software Update. Install an update that Software Update offers for your Mac. Apple's current update page lists macOS 27 Golden Gate as the newest major macOS release and notes that Software Update only offers software compatible with the Mac model.

For the current path and compatibility behavior, follow Apple's macOS Software Update instructions.

Step 3. Test the Mac in Safe Mode.

Safe Mode helps identify whether an issue may be caused by software that loads when the Mac starts. The startup procedure differs between Apple silicon and Intel Macs.

• Apple silicon: Shut down the Mac. Press and hold the power button until Loading startup options appears. Select a startup volume, hold Shift, then click Continue in Safe Mode.
• Intel Mac: Turn on or restart the Mac and immediately hold Shift until the login window appears. You may be asked to log in twice.

If sound works in Safe Mode but fails again during a normal startup, that suggests software loaded during startup deserves closer attention; it does not by itself identify a specific app. Apple's current Safe Mode instructions cover both Apple silicon and Intel Macs.

Use Apple Diagnostics When Built-In Speakers Still Fail

If known-good audio remains silent through the built-in speakers after output, accessory, update, and Safe Mode checks, shift from routine settings troubleshooting to hardware diagnosis.

Step 1. Prepare the Mac.

Install current macOS updates if possible, shut down the Mac, and disconnect external devices except the keyboard, mouse, display, Ethernet connection if needed, and power.

Step 2. Start Apple Diagnostics.

• Apple silicon: Hold the power button until startup options appear, release it when you see Options, then hold Command-D until the Mac restarts.
• Intel Mac: Turn on the Mac and immediately hold D. If that does not work, try Option-D.

Step 3. Follow the diagnostic results.

In macOS Tahoe 26 and later, Apple Diagnostics can ask you to choose a specific diagnostic. Record any reference code that appears. If the result does not resolve the problem and the internal speakers still fail, service is the appropriate next step rather than opening the Mac or attempting an undocumented hardware repair. See Apple's current Apple Diagnostics procedure for the full Apple silicon and Intel instructions.

Part 3. MacBook Air, MacBook Pro, and iMac Sound Differences

The same Sound settings apply across current Macs, but the devices attached to each model and the startup method used for diagnostics can change what you should look for.

MacBook Air and MacBook Pro No Sound

For MacBook Air sound not working or MacBook Pro sound not working, start by testing the built-in speakers with all headphones, docks, external displays, USB audio devices, and Bluetooth audio disconnected. Then choose the MacBook's own speakers under Sound > Output.

If headphones play normally but the built-in speakers remain silent even when the correct internal output is selected, do not assume an NVRAM or SMC reset is required. Follow the current output, update, Safe Mode, and Apple Diagnostics path first. On Apple silicon MacBook models, Safe Mode and Apple Diagnostics begin from startup options; Intel MacBook models use keyboard shortcuts during startup.

iMac No Sound or Audio Routed to a Display

For iMac sound not working, output routing is especially important when the iMac is connected to an external display, dock, receiver, or USB audio device.

Choose the output you actually want in Sound settings. If you want the iMac's own speakers, select the iMac speaker entry rather than the display or digital output. If you intentionally use a digital receiver, the Mac's normal volume controls may be unavailable because the receiver controls the listening level. That behavior is different from a broken Mac volume control.

Part 4. Is the Problem the Mac or the Audio File?

A system-wide no-sound problem and a single silent audio file require different fixes. Confirm which one you have before changing macOS settings or replacing hardware.

If One Audio or Video File Is Silent

If other apps, websites, and known-good files play through the built-in speakers, the Mac's speakers are working. Test the silent file in another compatible app and check the player volume, track selection, and whether the file actually contains an audio stream.

Do not reset macOS hardware settings just because one file will not play audio. A damaged, incomplete, unsupported, or incorrectly encoded file is a file-level problem, while Mac sound not working across all sources is a system or hardware troubleshooting problem.

If an Audio File Was Deleted or Went Missing

If an audio file was deleted or went missing from local storage, protect the data first: stop writing new files to the same volume, and check Trash, Time Machine, iCloud Drive, and other backup or sync locations. If the file is truly missing, Wondershare Recoverit Audio Recovery can help for a logical data-loss case — save recovered files to a different healthy location. Recovery is not guaranteed after data has been overwritten, and software recovery is not for drives with severe physical damage.

Important: Recoverit does not repair a silent speaker, change the active audio output, or fix a muted app. Its role is limited to recovering a missing audio file after a genuine data-loss event.

Part 5. Legacy Mac Sound Fixes to Skip as a First Step

Older troubleshooting articles often jump directly to Intel-era resets, Terminal commands, or unrelated disk repair. Those are not part of Apple's current first-line workflow for a Mac with no sound.

Do Not Start With Generic SMC or PRAM/NVRAM Resets

Old instructions commonly present SMC and PRAM/NVRAM resets as universal Mac audio fixes, but that framing no longer matches the current Mac hardware landscape.

Apple silicon Macs do not use the Intel startup shortcut for NVRAM resets, and SMC reset procedures are hardware-specific. For ordinary MacBook Air, MacBook Pro, or iMac no-sound cases, start with app volume, output routing, external devices, updates, Safe Mode, and diagnostics — use a hardware-specific reset only when current Apple documentation for that exact symptom and model calls for it.

Do Not Use Disk Utility or Terminal as a Generic Audio Fix

Disk Utility First Aid checks storage structures; it is not Apple's current generic remedy for silent Mac speakers. Likewise, killing the Core Audio process with a Terminal command should not replace the supported checks above for ordinary output-routing or mute problems.

This matters for both safety and diagnosis: an unrelated command can make troubleshooting harder without addressing the actual output path. If the current Apple workflow does not restore built-in sound, use Safe Mode and Apple Diagnostics to narrow the cause, then seek service when a hardware issue remains.

Conclusion

When Mac sound is not working, start by separating a single-app or file problem from a system-wide no-sound problem. Test another audio source, select the intended output, disconnect competing audio devices, and verify volume and mute settings. If sound is still missing, restart, install current macOS updates, test Safe Mode, and use Apple Diagnostics when the internal speakers still fail. Keep data recovery separate from audio troubleshooting: Recoverit is relevant only when an audio file itself has been deleted or gone missing.
