Then check that the correct microphone is selected in System Settings \u2192 Sound \u2192 Input and that the input volume is not at zero. For problems specific to Zoom, Teams or FaceTime, the application must be authorised individually. In 95 % of cases, this is a software problem that can be resolved in a few minutes.\n<\/div>\n\n<div class=\"toc-box\">\n<strong>Contents<\/strong>\n<ul>\n<li><a href=\"#tester\">Quickly test whether the microphone is working<\/a><\/li>\n<li><a href=\"#autorisations\">Check Confidentiality permissions<\/a><\/li>\n<li><a href=\"#parametres\">Configuring microphone parameters<\/a><\/li>\n<li><a href=\"#zoom-teams\">Problems specific to Zoom, Teams and FaceTime<\/a><\/li>\n<li><a href=\"#dictee\">Activate dictation to restart the microphone<\/a><\/li>\n<li><a href=\"#materiel\">When the microphone physically fails<\/a><\/li>\n<li><a href=\"#faq\">Frequently asked questions<\/a><\/li>\n<\/ul>\n<\/div>\n\n<h2 id=\"tester\">Quickly test whether the microphone is working<\/h2>\n\n<p>Before trying to repair, determine whether the problem is software or hardware. The quickest test is to use Siri or Voice Dictation, which are built into macOS and independent of third-party applications.<\/p>\n\n<h3>Test 1: via Siri<\/h3>\n\n<p>Maintain <strong>Cmd + Space<\/strong> or click on the Siri icon in the menu bar. Ask a simple question like \u00abWhat time is it? If Siri responds and displays your command as text, your microphone is working in hardware - the problem is with an application or authorisation.<\/p>\n\n<h3>Test 2: via Sound Settings<\/h3>\n\n<ol>\n<li>Open <strong>System settings \u2192 Sound \u2192 Input<\/strong>.<\/li>\n<li>Select <strong>Internal microphone<\/strong>.<\/li>\n<li>Speak in a normal voice.<\/li>\n<li>Observe the <strong>Input level<\/strong> The blue bars should react to your voice.<\/li>\n<\/ol>\n\n<p>If the bars move when you speak, the microphone is working. The problem lies elsewhere: authorisation denied to an application, the wrong input selected by the application itself, or a software conflict. If the bars don't move at all, go on to the next troubleshooting steps.<\/p>\n\n<div class=\"info-box tip\">\n<strong>Where is the microphone on your Mac?<\/strong> on recent MacBook Air models, the microphone is located on the left-hand side, level with the speaker grille. On recent MacBook Pros, three microphones are located under the speakers to the right of the keyboard. On iMacs, it's in the top bar near the camera. The Mac mini and Mac Pro don't have a built-in microphone - you need to use an external USB microphone.\n<\/div>\n\n<h2 id=\"autorisations\">Check Confidentiality permissions<\/h2>\n\n<p>Since macOS Mojave, every application has to request permission to access the microphone. If you've accidentally refused during an installation, the application simply can't use your microphone - even if everything else is configured correctly.<\/p>\n\n<h3>Procedure for authorising an application<\/h3>\n\n<ol>\n<li>Click on the Apple menu \u2192 <strong>System settings<\/strong>.<\/li>\n<li>In the sidebar, click on <strong>Confidentiality and security<\/strong>.<\/li>\n<li>In the list on the right, click on <strong>Microphone<\/strong>.<\/li>\n<li>You will see a list of applications that have requested access to the microphone.<\/li>\n<li>Activate the button next to the application causing the problem (Zoom, Teams, FaceTime, Skype, Discord, etc.).<\/li>\n<li><strong>Exit the application completely<\/strong> (Cmd + Q) and then launch it again for the change to take effect.<\/li>\n<\/ol>\n\n<p>If the application does not appear in the list, it has never requested authorisation. Launch the application and try to use the microphone - a system dialogue box should appear asking for authorisation. Click on <strong>Authorise<\/strong>.<\/p>\n\n<img decoding=\"async\" src=\"\/wp-content\/uploads\/2026\/04\/authorisation-microphone-mac-confidentiality.webp\" alt=\"Microphone privacy settings on macOS to authorise applications\" title=\"How to authorise an application to use the Mac microphone\" width=\"1200\" height=\"568\" loading=\"lazy\">\n\n<h2 id=\"parametres\">Configuring microphone parameters<\/h2>\n\n<p>If the authorisations are correct but the microphone still doesn't work, check the system settings.<\/p>\n\n<h3>Steps to follow<\/h3>\n\n<ol>\n<li>Open <strong>System settings \u2192 Sound \u2192 Input<\/strong>.<\/li>\n<li>Check that the correct microphone is selected. If you have several devices (internal microphone, USB headset, Bluetooth microphone), select the one you want to use.<\/li>\n<li>Check the <strong>Input volume<\/strong> The slider should be around 75 %. If it is at the minimum, your voice will not be picked up.<\/li>\n<li>Uncheck the <strong>Ambient noise reduction<\/strong> if it is ticked and you are testing (it can attenuate the voice in a quiet environment).<\/li>\n<li>Talk to us and look at the <strong>Input level<\/strong> They have to move.<\/li>\n<\/ol>\n\n<h3>Special case: external device<\/h3>\n\n<p>If you're using USB headphones, AirPods or a Bluetooth speaker with a microphone, macOS sometimes automatically selects this device as the default input. If the device is incorrectly connected, unplugged or broken, you won't get any input sound. Solution: explicitly select <strong>Internal microphone<\/strong> in the list, or unplug the external device.<\/p>\n\n<h2 id=\"zoom-teams\">Problems specific to Zoom, Teams and FaceTime<\/h2>\n\n<p>Each videoconferencing application has its own microphone settings which can overload those of the system. Here are the specific checks.<\/p>\n\n<h3>Zoom<\/h3>\n\n<ol>\n<li>Open Zoom \u2192 <strong>Settings<\/strong> (top right).<\/li>\n<li>Click on <strong>Audio<\/strong> in the sidebar.<\/li>\n<li>In the <strong>Microphone<\/strong>, select the correct device from the drop-down menu.<\/li>\n<li>Click on <strong>Testing the microphone<\/strong> and speak. The green bar should react.<\/li>\n<li>Uncheck <strong>Mute my microphone when I enter a meeting<\/strong> if you want to talk straight away.<\/li>\n<\/ol>\n\n<h3>Microsoft Teams<\/h3>\n\n<ol>\n<li>Click on your profile picture \u2192 <strong>Parameters<\/strong>.<\/li>\n<li>Click on <strong>Peripherals<\/strong>.<\/li>\n<li>In <strong>Microphone<\/strong>, select the correct device.<\/li>\n<li>Launch a <strong>Test call<\/strong> to check that your voice is being received.<\/li>\n<\/ol>\n\n<h3>FaceTime<\/h3>\n\n<p>FaceTime automatically uses the system microphone. If FaceTime doesn't pick up your voice, the problem is with the system settings (Authorisations or System Settings \u2192 Sound \u2192 Input), not FaceTime itself. Check these settings first before reinstalling the application.<\/p>\n\n<div class=\"info-box warning\">\n<strong>Important information:<\/strong> certain professional applications (Logic Pro, GarageBand, OBS Studio) take exclusive control of the microphone. If one of these applications is open in the background, Zoom or Teams will not be able to access the microphone. Quit these applications completely before launching a call.\n<\/div>\n\n<h2 id=\"dictee\">Activate dictation to restart the microphone<\/h2>\n\n<p>It's a little-known but often effective trick: activate the <strong>Voice dictation<\/strong> macOS forces the system to reload audio drivers and microphone permissions. This resolves persistent bugs that resist other methods.<\/p>\n\n<ol>\n<li>Open <strong>System settings \u2192 Keyboard<\/strong>.<\/li>\n<li>Scroll to <strong>Dictation<\/strong>.<\/li>\n<li>Activate <strong>Dictation<\/strong>.<\/li>\n<li>Accept the download of the speech recognition files (a few hundred MB).<\/li>\n<li>Once activated, test your microphone again.<\/li>\n<\/ol>\n\n<p>This works particularly well after a macOS update that has disrupted the audio drivers. You can disable Dictation immediately afterwards if you don't want to use it.<\/p>\n\n<h2 id=\"materiel\">When the microphone physically fails<\/h2>\n\n<p>If all the software solutions have failed and Siri itself can no longer hear you, the microphone may be physically faulty. There are several possible causes.<\/p>\n\n<table class=\"tg-table\">\n<thead>\n<tr>\n<th>Symptom<\/th>\n<th>Probable cause<\/th>\n<th>Solution<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><span class=\"cell-label\">No microphone response, even via Siri<\/span><\/td>\n<td><span class=\"cell-desc\">Microphone disconnected or faulty<\/span><\/td>\n<td><span class=\"cell-desc\">Diagnosis and replacement<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Very weak and distorted sound<\/span><\/td>\n<td><span class=\"cell-desc\">Damaged microphone membrane<\/span><\/td>\n<td><span class=\"cell-desc\">Replacing the microphone<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Micro HS after liquid damage<\/span><\/td>\n<td><span class=\"cell-desc\">Oxidation of contacts<\/span><\/td>\n<td><span class=\"cell-desc\">Deoxidation or replacement<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Microphone out of order after a fall<\/span><\/td>\n<td><span class=\"cell-desc\">Disconnected or broken tablecloth<\/span><\/td>\n<td><span class=\"cell-desc\">Reconnection or replacement of water table<\/span><\/td>\n<\/tr>\n<tr>\n<td><span class=\"cell-label\">Constant noise or murmur<\/span><\/td>\n<td><span class=\"cell-desc\">Internal short circuit<\/span><\/td>\n<td><span class=\"cell-desc\">Motherboard diagnostics<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n<p>On most recent MacBooks, the microphone is integrated into the top case (the keyboard + top chassis assembly) and cannot be replaced individually.

First check that Teams is authorised in System Settings \u2192 Privacy and Security \u2192 Microphone. Then, in Teams, go to Settings \u2192 Devices and select the correct microphone. Exit and relaunch Teams after each change.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>My Mac mini or Mac Pro has no microphone, is this normal?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>Yes, that's quite normal. The Mac mini, Mac Pro and Mac Studio don't have a built-in microphone. To use a microphone with these machines, you'll need to plug in a USB headset with a mic, a dedicated USB mic or use AirPods. Once plugged in, the device appears in System Settings \u2192 Sound \u2192 Input.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>My microphone was working before the macOS update. What should I do?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>MacOS updates sometimes reset Confidentiality authorisations. Go to System Settings \u2192 Privacy &amp; Security \u2192 Microphone and check that your applications are still authorised. Enable Voice Dictation to force the audio drivers to reload. If the problem persists on an Intel Mac, reset the NVRAM.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>How do I know if my microphone is physically out of order?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>The most reliable test is Siri. If Siri hears you and transcribes your commands correctly, the microphone is working in hardware - the problem is software. If Siri doesn't respond at all, and no bars move in System Settings \u2192 Sound \u2192 Input even when speaking loudly, the microphone is probably faulty or disconnected.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>My microphone can hear but the sound is very weak, why?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>Check the Input Volume in System Settings \u2192 Sound \u2192 Input - it should be around 75 %. Uncheck Ambient Noise Reduction, which can muffle your voice. Make sure nothing is physically obstructing the microphone (case, sticker, dust in the grille). On recent MacBooks, gently clean the microphone grille with compressed air.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>Why do people tell me I spit?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>There are several possible causes: input volume too high which saturates the microphone (reduce to 60-70 %), interference from a Bluetooth device, a physically damaged microphone (pierced membrane), or incorrectly configured audio filters in the videoconferencing application. Test with a USB headset to isolate the problem.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>How can I completely reset my microphone authorisations?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>Open Terminal and type : <code>tccutil reset Microphone<\/code>. Press Enter and enter your password. This command deletes all existing microphone authorisations. The next time you launch an application that uses the microphone, it will ask you for authorisation again.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>My microphone works but Siri can't hear me, why?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>Siri uses a specific audio processing chain. Check that Siri is activated in System Settings \u2192 Siri and Spotlight. Also check that Siri's language matches your spoken language. Deactivate then reactivate Siri to force a reset. If the problem persists, disconnect and then reconnect to your Apple ID.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>The microphone on my USB headset doesn't work, is this a Mac problem?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>First check in System Settings \u2192 Sound \u2192 Input that headphones are selected as the input source. Then check MIDI Audio Configuration (Applications \u2192 Utilities) to see if the device is correctly detected. Test the headphones on another computer to confirm that they work. If so, the problem is a driver or USB conflict on your Mac.<\/p><\/div>\n<\/div>\n\n<div class=\"faq-item\">\n<div class=\"faq-question\"><span>Can MAC Repair repair a faulty Mac micro?<\/span><span class=\"faq-toggle\">+<\/span><\/div>\n<div class=\"faq-answer\"><p>Yes, with over 15 years' experience since 2010, we diagnose and repair microphone faults: reconnection of the mat, deoxidation after liquid damage, replacement of the microphone module, micro-soldering of the audio chip. 180-day guarantee on all repairs.
