市场上几乎每台 Mac 都配备了内置摄像头，让您可以快速拍照、通过FaceTime或Zoom进行视频通话，或者使用(Zoom)Photo Booth应用程序中的滤镜和效果展示您古怪的一面。您只需打开 Mac 相机(turn your Mac camera on)并开始使用 - 无需额外软件或额外设置。
Mac上的摄像头坏了意味着您的窗口无法与外界接触。您可以使用一些鲜为人知的技巧和技巧来修复您的Mac相机，而不是失去进行视频通话或自拍的能力。(Mac)如果您的Mac相机无法正常工作，那么您可以尝试以下一些解决方案来解决问题。
检查相机镜头(Check the Camera Lens)
显而易见的答案有时是最好的。如果您希望避免窥探者，在Mac(Mac)的摄像头上贴上贴纸可能是一个明智之举，但被挡住的摄像头是无用的摄像头，这可能是您的Mac摄像头无法工作的原因，而是显示黑色源。
在您尝试任何其他修复之前，请确保检查您的相机镜头是否有任何障碍。如果贴纸或其他物体挡住您的路，您不会收到警报 - 摄像头画面只会显示黑色。
如果您的相机馈送中有任何东西，请务必在尝试使用相机之前将其移除。但是，如果您的摄像头画面保持黑色，并且没有任何障碍，则您需要尝试以下修复方法之一。
使用其他应用程序(Use Another App)
Mac用户不需要其他应用程序来使用他们的网络摄像头，因为内置的Photo Booth应用程序应该允许您拍照和录制视频。但是，如果此应用程序（或其他应用程序，如Facetime）无法正常工作，请通过尝试其他应用程序来检查问题是否与您的相机有关。
这可能是另一个Apple应用程序（例如Facetime over Photo Booth）或第三方应用程序。Hand Mirror等应用(Apps)程序可让您从菜单栏中快速访问摄像头源，而Skype等其他应用程序则使用您的摄像头和麦克风源提供视频通话，前提是您的麦克风设置正确(microphone is set up correctly)。
尝试不同的相机应用程序将帮助您确定您的相机是否与某个应用程序有问题，或者它是否指向更广泛的软件或硬件问题。尝试另一个应用程序还可以帮助强制优先考虑哪个应用程序可以访问您的相机，因为只有一个应用程序应该能够一次访问您的Mac相机源。
在系统偏好设置中确认应用权限(Confirm App Permissions in System Preferences)
较新(Newer)版本的 macOS 会自动限制对相机源的访问。这可以防止窥探者、设计不良的应用程序和流氓网站在未经您明确许可的情况下访问您的相机。
虽然Photo Booth和Facetime等应用程序通常会自动获得相机访问权限，但(Facetime)Skype或Zoom等第三方应用程序不会。您可以在系统偏好设置(System Preferences )应用程序中检查您的相机权限。
- 要打开系统偏好设置(System Preferences)，请选择左上角的Apple 菜单图标。(Apple menu icon )从菜单中，选择系统偏好设置(System Preferences)选项。
- 在“系统偏好设置”(System Preferences)窗口中，选择“安全和隐私”(Security & Privacy )选项。
- 在“安全和隐私”(Security & Privacy )菜单的“隐私(Privacy)”选项卡中，选择左侧的“相机”选项。(Camera)在右侧，将列出可能访问相机的应用程序列表。有权使用您的相机的应用程序(Apps)将启用其名称旁边的复选框，因此请确保启用您希望在此处使用的任何相机应用程序旁边的复选框。您可能需要先选择菜单底部的锁定图标进行身份验证。(lock icon)
在“系统偏好设置”(System Preferences)菜单中启用第三方相机应用程序的权限后，关闭并重新打开该应用程序以确保已成功授予相机访问权限。
检查屏幕时间中的家长控制(Check Parental Controls in Screen Time)
屏幕使用时间(Time)是 macOS 中的一组家长控制，可让您限制其用户可以使用的功能、应用程序和服务。这对于可能想要限制相机访问的父母来说是完美的，但它是双向的。如果您已经屏蔽了摄像头并忘记了它，那么您也将无法使用您的摄像头。
- 要检查屏幕时间(Screen Time)是否阻止了相机访问，您需要打开系统偏好设置(System Preferences)。从菜单栏上的Apple 菜单(Apple menu)中，选择系统偏好设置(System Preferences)选项。
- 在System Preferences中，选择Screen Time选项。
- 从屏幕时间(Screen Time )菜单的左侧菜单中选择内容和隐私(Content & Privacy)。在应用程序(Apps)选项卡下，确保启用了相机(Camera)选项旁边的复选框。如果不是，您将根本无法使用相机（即使使用系统应用程序）。
在Screen Time(Screen Time)中恢复对相机的访问后，您可能需要关闭并重新打开相机应用程序才能正常工作。
重新启动基本相机系统进程(Restart Essential Camera System Processes)
内部Mac摄像头由在 macOS 后台运行的系统进程控制。重新启动这些进程有时可以解决可能导致Mac相机停止工作的软件冲突或问题。
- 为此，您需要从Launchpad打开(Launchpad)终端(Terminal)应用程序。在终端窗口中，键入sudo killall VDCAssistant。如果您运行的是旧版本的 macOS，您可能还需要输入sudo killall AppleCameraAssistant。如果系统要求您输入系统密码，请输入此密码以确保命令成功运行。
一旦这些进程停止，您可以通过打开其中一个内置的Mac相机应用程序（如Photo Booth）手动重新启动它们。
检查您的相机是否被正确检测到(Check Your Camera Is Detected Properly)
随着大多数潜在的软件修复用尽，您可能需要查看您的内部摄像头本身是否正常工作。如果您的Mac无法检测到它，那么这可能表明存在硬件问题，您可能需要寻求维修。
- 要检查是否检测到您的内置Mac摄像头，请选择左上角的Apple 菜单图标。(Apple menu icon )从菜单中，选择关于本机(About This Mac )选项。
- 在概览(Overview )选项卡中，选择系统报告(System Report )按钮。
- 在系统信息(System Information )菜单中，选择硬件(Hardware )选项卡下列出的摄像头。(Camera, )在右侧，您应该会看到有关您的内置摄像头的信息，包括摄像头类型和型号 ID 号。
如果信息未列出，则说明未检测到您的相机，您需要联系Apple进行维修。
进一步解决 Mac 相机问题(Troubleshooting Mac Camera Issues Further)
上述步骤应该有助于让您的Mac相机再次正常工作。大多数时候，Macbook相机的问题归结为权限问题，主要的网络浏览器(web browsers blocking camera access)默认阻止相机访问。如果您在“系统偏好设置”(System Preferences)菜单中启用了这些权限，则需要进一步解决您的问题。
如果其他方法都不起作用，则可能是更深层次的软件问题，甚至是硬件故障，因此请先尝试重置您的 PRAM 和 SMC(resetting your PRAM and SMC)。如果失败，请尝试重置您的 Mac(resetting your Mac)以将其恢复为出厂设置并删除任何冲突的应用程序或服务，但不要忘记先尝试使用USB 网络摄像头(USB webcam)查看您的硬件是否有故障。
Mac Camera Not Working? 6 Ways to Fix
Almost every Mac on the market comes with a built-іn camera, allowing you tо take quick pictυres, stagе video calls over FaceTime or Zoom, or show your quirky side using the filters and effects in the Photo Booth app. You just need to turn your Mac camera on and get started—no extra software or additional setup is necessary.
A broken camera on your Mac means losing your window to the outside world. Rather than lose the ability to make video calls or take selfies, you may be able to fix your Mac camera using a few tricks and tips that aren’t so well known. If your Mac camera is not working, then here are some solutions you can try to fix the problem.
Check the Camera Lens
The obvious answer is sometimes the best. Putting a sticker over your Mac’s camera might be a sensible move if you prefer to avoid snoopers, but a blocked camera is a useless camera and could be why your Mac camera is not working, displaying a black feed instead.
Before you try any other fix, make sure to check that there isn’t anything in the way of your camera lens. You won’t be alerted if stickers or other objects are in the way—the camera feed will simply show black.
If there is something in the way of your camera feed, be sure to remove it before you try to use your camera. However, if your camera feed stays black, and there’s nothing in the way, you’ll need to try one of the following fixes instead.
Use Another App
Mac users don’t need another app to use their webcam, as the built-in Photo Booth app should allow you to take pictures and record videos. However, if this app (or another app, like Facetime) isn’t working, then check that the problem is specific to your camera by trying another app.
This could be another Apple app (Facetime over Photo Booth, for instance) or a third-party app. Apps like Hand Mirror give you quick access to your camera feed from the menu bar, while other apps like Skype use your camera and microphone feed to offer video calls, assuming your microphone is set up correctly.
Trying different camera apps will help you determine if your camera has trouble with a certain app, or if it points to a wider software or hardware issue. Trying another app can also help to force priority over which app has access to your camera, as only one app should be able to access your Mac camera feed at once.
Confirm App Permissions in System Preferences
Newer versions of macOS limit access to your camera feed automatically. This prevents snoopers, badly-designed apps, and rogue websites from accessing your camera without your explicit permission.
While apps like Photo Booth and Facetime will typically be granted camera access automatically, third-party apps like Skype or Zoom won’t. You can check your camera permissions in the System Preferences app.
- To open System Preferences, select the Apple menu icon in the top-left corner. From the menu, select the System Preferences option.
- In the System Preferences window, select the Security & Privacy option.
- In the Privacy tab of the Security & Privacy menu, select the Camera option on the left. On the right, a list of apps with possible camera access will be listed. Apps with permission to use your camera will have the checkbox next to their names enabled, so make sure to enable the checkbox next to any camera apps you wish to use here. You may need to select the lock icon at the bottom of the menu to authenticate first.
Once you’ve enabled the permissions for your third-party camera app in the System Preferences menu, close and reopen the app to ensure that camera access has been granted successfully.
Check Parental Controls in Screen Time
Screen Time is a set of parental controls in macOS that allows you to limit the features, apps, and services that can be used by its users. This is perfect for parents who might want to limit camera access, but it works both ways. If you’ve blocked the camera and forgotten about it, then you won’t be able to use your camera either.
- To check whether camera access is blocked by Screen Time, you’ll need to open System Preferences. From the Apple menu on your menu bar, select the System Preferences option.
- In System Preferences, select the Screen Time option.
- Select Content & Privacy from the left-hand menu in the Screen Time menu. Under the Apps tab, make sure that the checkbox next to the Camera option is enabled. If it isn’t, you won’t be able to use your camera at all (even with system apps).
Once access to your camera has been restored in Screen Time, you may need to close and reopen the camera app for it to work correctly.
Restart Essential Camera System Processes
The internal Mac camera is controlled by system processes that run in the background of macOS. Restarting these processes can sometimes fix software conflicts or issues that can cause the Mac camera to stop working.
- To do this, you’ll need to open the Terminal app from the Launchpad. In the terminal window, type sudo killall VDCAssistant. If you’re running an older version of macOS, you may need to type sudo killall AppleCameraAssistant too. If you’re asked for your system password, type this in to ensure the commands successfully run.
Once these processes have stopped, you can restart them manually by opening one of the built-in Mac camera apps like Photo Booth.
Check Your Camera Is Detected Properly
With most of the potential software fixes exhausted, you may need to look at whether your internal camera itself is working. If your Mac can’t detect it, then this could point to a hardware issue, and you may need to seek a repair.
- To check whether your internal Mac camera is being detected, select the Apple menu icon in the top-left. From the menu, select the About This Mac option.
- In the Overview tab, select the System Report button.
- In the System Information menu, select Camera, listed under the Hardware tab. On the right, you should see information about your internal camera listed, including the type of camera and the model ID number.
If the information isn’t listed, then your camera hasn’t been detected, and you’ll need to contact Apple for repair.
Troubleshooting Mac Camera Issues Further
The steps above should help get your Mac camera working properly again. Most of the time, issues with a Macbook camera are down to permissions, with major web browsers blocking camera access by default. If you’ve enabled these permissions in the System Preferences menu, then you’ll need to troubleshoot your issues further.
If nothing else works, it could point to a deeper software problem, or even a hardware fault, so try resetting your PRAM and SMC first. If that fails, try resetting your Mac to restore it to factory settings and remove any conflicting apps or services, but don’t forget to try using a USB webcam to see if your hardware is faulty first.
