Mac 的屏幕截图(Screenshot)应用程序提供了多种方式来快速轻松地截取屏幕截图。但尽管已集成到 macOS 中，但它偶尔会停止正常运行。
例如，屏幕截图(Screenshot)应用程序可能拒绝显示，其键盘快捷键也可能没有响应。或者，它可能会截取屏幕截图但无法保存。
错误和故障、权限不足和设置冲突是可能导致屏幕截图无法在Mac上运行的一些因素。发生这种情况时，下面的修复列表应该可以帮助您解决问题。
1. 重启你的 Mac
如果您刚才在Mac上截屏没有任何问题，那么您可能正在处理截屏(Screenshot)应用程序中的一个小故障。解决此问题的最佳方法是重新启动Mac。在继续进行其余修复之前立即执行此操作。
2. 更新你的 Mac
如果您使用的是主要 macOS 版本的早期迭代（例如 macOS Big Sur），最好应用任何待处理的系统软件更新。这样做可以解决干扰系统相关功能（例如屏幕截图应用程序）在(Screenshot)Mac上正常工作的已知错误。
1. 打开Apple菜单并选择系统偏好设置(System Preferences)。
2. 选择软件更新(Software Update)。
3. 选择立即更新(Update Now)以安装任何待处理的更新。
macOS 的Beta(Beta)版本也可能导致Mac出现问题。如果以下修复都不起作用，请(Make)确保将其更新到最新的 beta 版本或降级到稳定频道。
3. 限制可能是一个因素
某些程序和网站（例如Apple TV 和Netflix）禁止(Netflix—prohibit)您截屏。发生这种情况是由于受版权保护的内容的复杂性。如果您的屏幕截图显示为空白，其中没有任何内容，这可能就是原因。
4.检查屏幕截图键盘快捷键(Screenshot Keyboard Shortcuts)
如果您在使用 Screenshot 应用程序的键盘快捷键(using the Screenshot app’s keyboard shortcuts)时遇到问题，您必须检查它们是否存在无效或不正确的组合键。
1. 打开Apple菜单并选择系统偏好设置(System Preferences)。
2. 选择键盘(Keyboard)。
3. 切换到快捷方式(Shortcuts )选项卡。
4. 选择截图(Screenshots)。
5. 仔细检查键盘快捷键并根据需要激活或修改它们。
5.设置截图保存位置
默认情况下，Mac将屏幕截图保存到桌面。但是，如果您在截屏后找不到屏幕截图，则可能是您之前指定了不同的位置。你应该仔细检查一下。
1. 按Shift + Command + 5调出屏幕截图(Screenshot)应用程序。或者，转到Finder > Applications > Utilities并打开Screenshot。
2. 选择浮动工具栏上的选项。(Options)
3. 您应该在Save to(Save to)下看到当前的保存位置。您可以从列表中选择一个备用目的地，或使用“其他位置(Other Location)”选项选择另一个目录。
6.修改保存位置权限
如果您的屏幕截图仍然没有出现在桌面或选择的保存位置，您必须检查目录的读写权限。
1. 打开查找器(Finder)。然后，找到并按住 Control 单击保存目标（例如Desktop）。
2. 选择获取信息(Get Info)。
3. 展开共享和权限(Sharing & Permissions)部分。
4. 确保选择您的 Mac 帐户名称旁边的读取和写入。(Read & Write)
5. 此外，请确保取消选中General部分下Locked旁边的框。(Locked)
6. 关闭信息(Info)窗格。
如果您必须在步骤4或5中进行修改，您的屏幕截图应该会正确保存。
7.检查第三方云存储(Cloud Storage) 服务(Services)
您的屏幕截图会在您拍摄后立即从桌面上消失吗？如果您在Mac(Mac)上安装了第三方云存储服务，它可能会自动将它们移动到其同步文件夹中。以下是在OneDrive(OneDrive)和Dropbox上停止这种情况的方法：
在 OneDrive 中禁用屏幕截图备份(Disable Screenshot Backups in OneDrive)
1. 选择Mac 菜单栏上的OneDrive图标。(OneDrive )
2. 选择帮助和设置(Help and Settings)>首选项(Preferences)。
3. 在Preferences选项卡下，取消选中(Preferences )Save screenshots to OneDrive旁边的框。
在 Dropbox 中禁用屏幕截图备份(Disable Screenshot Backups in Dropbox)
1. 选择Mac 菜单栏上的Dropbox图标。(Dropbox )
2. 选择您的头像，然后选择首选项(Preferences)。

8. 以安全模式启动您的 Mac
将Mac(Mac)启动到安全模式(Safe Mode)通常有助于解决随机出现的与系统相关的缺陷。如果您继续遇到屏幕截图(Screenshot)应用程序的问题，您应该立即执行此操作。
根据您的Mac是采用Intel芯片组还是Apple Silicon 芯片组(Apple Silicon chipset)，您需要遵循两种稍微不同的程序之一才能进入安全模式(Mode)。
配备英特尔芯片的 Mac(Macs With Intel Chips)
1. 关闭你的 Mac。
2.等待(Wait)10 秒。然后，按住Shift键并打开 Mac。
3.看到 Apple 标志后松开Shift键。(Shift )
配备 Apple 硅芯片的 Mac(Macs With Apple Silicon Chips)
1. 关闭你的 Mac。
2.等待(Wait)30 秒。然后，按住电源(Power )按钮，直到进入带有启动磁盘的屏幕。
3. 选择 macOS 启动盘。
4. 按住Shift键并选择Continue in Safe Mode。
5. 松开Shift键。
一旦您的Mac启动到安全模式(Safe Mode)，请尝试截屏。如果可行，请正常重新启动您的Mac并拍摄另一个屏幕截图。在大多数情况下，屏幕截图(Screenshot)应用程序及其快捷方式都应该像往常一样重新开始工作。
9. 扫描 Mac 上的恶意软件
您可能听说过Mac(Macs)不易受到恶意软件的影响，但这不一定是真的(that’s not necessarily true)。恶意程序可以劫持 macOS 的功能和快捷方式，因此您必须排除Screenshot应用程序是否仍然会导致问题。
Malwarebytes是一个专门的恶意软件清除程序，可以帮助您。使用它来执行扫描并检查它是否在您的Mac上检测到任何危险。
10. 重置 Mac 的 NVRAM
Mac上的NVRAM（非易失性随机存取存储器）保存少量的杂项数据，这些数据可能会过时并阻碍 macOS 中的各种功能。因此(Hence)，重置它可能会修复屏幕截图(Screenshot)应用程序。但是，您只能在配备英特尔(Intel)芯片组的Mac上执行此操作。(Macs)
1. 关闭Mac并等待 10 秒钟。
2. 重新启动您的Mac，但同时按住Option、Command、P和R键。
3. 在您的Mac(Mac)第二次播放启动铃声后松开按键。如果您的Mac配备Apple T2 安全芯片，请在(Apple T2 Security Chip)Apple徽标出现并消失两次后 松开按键。

您现在可以截图
Mac上与屏幕截图相关的问题通常很容易解决，上面的修复希望对您有所帮助。如果某个特定问题反复出现，纠正该问题的最佳方法是在Mac上安装任何新的系统软件更新，只要它们可用。您还可以清除 Mac 的系统缓存(clear the Mac’s system cache)，看看是否有所不同。
除了 Mac 的Screenshot应用程序之外，一种不太方便但原生的截屏方式是使用Preview 应用程序(Preview app)（选择File > Take a Screenshot）。您还可以查看Mac 的顶级第三方截图替代品(top third-party snipping alternatives for the Mac)。
Screenshot Not Working on Mac? 10 Troubleshooting Tips
The Mac’s Screenshot app provides multiple wаys to grab screеnshots quicklу and easily. But despite being integrated into macOS, it can occasionally cease to functiоn correctly.
For instance, the Screenshot app may refuse to show up, and its keyboard shortcuts might also not respond. Or, it could appear to take screenshots but fail to save them.
Bugs and glitches, insufficient permissions, and conflicting settings are some of the things that may lead to screenshots not working on the Mac. When that happens, the list of fixes below should help you sort things out.
1. Restart Your Mac
If you were taking screenshots on your Mac without any trouble just a moment ago, you’re probably dealing with a minor glitch in the Screenshot app. The best way to fix that is to restart the Mac. Do that now before moving on with the rest of the fixes.
2. Update Your Mac
If you’re using an early iteration of a major macOS release (say macOS Big Sur), it’s a good idea to apply any pending system software updates. Doing so resolves known bugs that interfere with system-related functionalities—such as the Screenshot app—from working correctly on the Mac.
1. Open the Apple menu and select System Preferences.
2. Select Software Update.
3. Select Update Now to install any pending updates.
Beta versions of macOS can also cause problems on the Mac. Make sure to update it to the latest beta release or downgrade to the stable channel if none of the fixes below work.
3. Restrictions May Play a Factor
Some programs and websites—such as Apple TV and Netflix—prohibit you from taking screenshots. That happens due to complications with copyrighted content. If your screenshots appear blank with nothing in them, that’s probably the reason why.
4. Check Screenshot Keyboard Shortcuts
If you have trouble using the Screenshot app’s keyboard shortcuts, you must review them for inactive or incorrect key combinations.
1. Open the Apple menu and select System Preferences.
2. Select Keyboard.
3. Switch to the Shortcuts tab.
4. Select Screenshots.
5. Double-check the keyboard shortcuts and activate or modify them as needed.
5. Set Screenshot Save Location
By default, the Mac saves screenshots to the desktop. However, if you can’t find your screenshots after taking them, you might have specified a different location previously. You should double-check that.
1. Press Shift+Command+5 to bring up the Screenshot app. Or, go to Finder > Applications > Utilities and open Screenshot.
2. Select Options on the floating toolbar.
3. You should see the current save location under Save to. You can pick an alternative destination from the list or choose another directory using the Other Location option.
6. Modify Save Location Permissions
If your screenshots still don’t appear on the desktop or the chosen save destination, you must check the directory’s read and write permissions.
1. Open Finder. Then, locate and control-click the save destination (e.g., Desktop).
2. Select Get Info.
3. Expand the Sharing & Permissions section.
4. Make sure to select Read & Write next to your Mac account name.
5. Additionally, make sure to uncheck the box next to Locked under the General section.
6. Close the Info pane.
If you had to make modifications in steps 4 or 5, your screenshots should save correctly going forward.
7. Check Third-Party Cloud Storage Services
Do your screenshots disappear from the desktop as soon as you take them? If you have a third-party cloud storage service installed on your Mac, it’s probably automatically moving them to its sync folder. Here’s how to stop that on OneDrive and Dropbox:
Disable Screenshot Backups in OneDrive
1. Select the OneDrive icon on the Mac’s menu bar.
2. Select Help and Settings > Preferences.
3. Under the Preferences tab, uncheck the box next to Save screenshots to OneDrive.
Disable Screenshot Backups in Dropbox
1. Select the Dropbox icon on the Mac’s menu bar.
2. Select your profile portrait and choose Preferences.
3. Switch to the Backups tab. Then, uncheck the box next to Share screenshots and screen recordings using Dropbox.
8. Launch Your Mac in Safe Mode
Booting your Mac into Safe Mode often helps resolve system-related flaws that crop up randomly. If you continue to experience issues with the Screenshot app, you should do that now.
Depending on whether your Mac has an Intel or an Apple Silicon chipset, you need to follow one of slightly two different procedures to get into Safe Mode.
Macs With Intel Chips
1. Turn off your Mac.
2. Wait for 10 seconds. Then, hold down the Shift key and turn on your Mac.
3. Release the Shift key once you see the Apple logo.
Macs With Apple Silicon Chips
1. Turn off your Mac.
2. Wait for 30 seconds. Then, press and hold the Power button until you get to the screen with the startup disks.
3. Select the macOS startup disk.
4. Hold down the Shift key and select Continue in Safe Mode.
5. Release the Shift key.
Once your Mac boots into Safe Mode, try taking a screenshot. If that works, reboot your Mac normally and take another screenshot. In most cases, both the Screenshot app and its shortcuts should start to work again as usual.
9. Scan for Malware on Your Mac
You might’ve heard about Macs being insusceptible to malware, but that’s not necessarily true. Malicious programs can hijack macOS functionalities and shortcuts, so you must rule that out if the Screenshot app still causes trouble.
Malwarebytes is a dedicated malware remover that can help you with that. Use it to perform a scan and check if it detects anything dangerous on your Mac.
10. Reset Your Mac’s NVRAM
The NVRAM (non-volatile random-access memory) on the Mac holds tiny amounts of miscellaneous data that can go obsolete and impede various functions in macOS. Hence, resetting it may fix the Screenshot app. You can, however, only do that on Macs with Intel chipsets.
1. Turn off your Mac and wait for 10 seconds.
2. Reboot your Mac but hold down the Option, Command, P, and R keys together at the same time.
3. Release the keys after your Mac plays the startup chime for the second time. If your Mac has an Apple T2 Security Chip, release the keys once the Apple logo shows up and disappears twice.
That should reset the NVRAM. For comprehensive step-by-step instructions, check out this post about resetting the NVRAM on your Mac.
You Can Take Screenshots Now
Screenshot-related problems on the Mac are typically easy to resolve, and the fixes above hopefully helped you with that. If a specific issue crops up repeatedly, the best way to rectify that is to install any new system software updates on the Mac as soon as they become available. You can also clear the Mac’s system cache and see if that makes a difference.
Besides the Mac’s Screenshot app, a less convenient but native way to capture screenshots is to use the Preview app (select File > Take a Screenshot). You can also take a look at the top third-party snipping alternatives for the Mac.
