无法在Mac笔记本电脑或台式机上复制或粘贴文件、文本和其他项目？我们将解释为什么会发生这种情况，并为 macOS 中的复制和粘贴问题推荐可能的修复方法。
在继续之前，请确认您使用分配给复制、剪切和粘贴功能的正确组合键。作为复习：“Command + C”复制数据，“Command + X”剪切数据，而“Command + V”粘贴复制的数据。
如果Mac 的键盘出现问题，(problem with your Mac’s keyboard)这些快捷键可能不起作用。也许，某些键在键盘上无法正常工作(certain keys aren’t working properly)。如果热键不起作用，请尝试从 Mac 的菜单栏中复制和粘贴数据。
选择文件或文本，选择菜单栏上的编辑，然后选择(Edit)剪切(Cut)、复制(Copy)、粘贴(Paste)或粘贴并匹配样式(Paste and Match Style)。
您还可以从 macOS 上下文菜单中复制和粘贴数据。选择(Select)并右键单击（或按住 Control 单击）要复制的内容，右键单击或按Control +单击，(click,)然后在上下文菜单中选择“复制”。(Copy)前往目标文件夹、应用程序或文本字段，然后在上下文菜单上选择粘贴。(Paste)
如果您无法使用这些方法中的任何一种在Mac上复制和粘贴，请尝试以下故障排除步骤。(Mac)
1.强制关闭并重新打开您的应用程序
如果问题是特定于一些Mac应用程序；强制退出并重新打开受影响的应用程序。这会刷新应用程序并可能恢复复制和粘贴功能。
- 按Command +空格键(Space bar)启动Spotlight Search。在搜索框中输入活动监视器，然后按(activity monitor)回车(return)键或选择活动监视器(Activity Monitor)。
或者，转到Finder > Applications > Utilities > Activity Monitor。
- 选择受影响的应用程序并选择活动监视器工具栏中的停止(Stop)图标（x 图标(x icon)）。
- 在确认提示中选择强制退出。(Force Quit)
对所有受影响的应用重复(Repeat)这些步骤。重新启动应用程序并检查您是否可以复制或粘贴内容。
2.强制关闭Pboard服务器
“ Pboard ”代表“粘贴(Pasteboard)板” 。粘贴板(Pasteboard)服务器是一个重要的后台进程，它在您的Mac上复制和粘贴数据方面发挥着重要作用。Pboard用作 macOS 的剪贴板守护程序 - 临时存储，用于保存和传送从源复制的数据到目标文件夹或应用程序。
如果粘贴板服务器出现问题，复制和粘贴可能无法在您的计算机上运行。强制退出该过程(Force-quitting the process)将清除 Mac 的剪贴板，刷新复制和粘贴功能，并帮助恢复秩序。
通过活动监视器强制关闭 Pboard(Force Close Pboard via the Activity Monitor)
在Activity Monitor(Activity Monitor)中终止粘贴板服务器，等待几秒钟，然后在 macOS 自动重启进程时尝试复制和粘贴内容。
- 前往Finder > Applications > Utilities并双击Activity Monitor。
- 点击右上角的搜索图标(search icon)。
- 在搜索栏中键入pboard ，然后在“活动监视器”窗口中双击pboard。
- 选择退出(Quit)。
- 选择强制退出(Force Quit)按钮。
通过终端强制关闭板(Force Close Pboard via the Terminal)
您还可以使用 macOS 中的终端终止系统进程(kill system processes using Terminal in macOS)。以下是如何使用终端命令(Terminal command)强制关闭印刷板进程。
- 转到Finder > Applications > Utilities并双击Terminal。
- 在控制台中粘贴或键入sudo killall pboard并按键盘上的回车(return)键。
- 输入您的 Mac 密码，然后按回车(return)键。
关闭终端(Close Terminal)并检查您是否可以在所有应用程序中复制和粘贴数据。
3.强制关闭WindowServer
WindowServer是另一个对(WindowServer)Mac操作系统的运行至关重要的系统组件。终止WindowServer可以帮助消除导致复制和粘贴无法在您的(WindowServer)Mac上工作的系统级故障。
我们建议在强制退出WindowServer(WindowServer)之前关闭所有活动的应用程序并保存所有正在进行的工作。这是因为该操作会将您从Mac中注销，关闭所有活动的应用程序，并刷新您的Mac操作系统。
当您登录Mac时，所有关闭的应用程序都会自动启动，但您可能会丢失未保存的数据。
- 打开Activity Monitor，在搜索栏中输入windowserver，然后双击WindowServer。
- 选择退出(Quit)。
- 选择强制退出(Force Quit)。
在登录屏幕上输入您的 Mac 密码，然后检查您现在是否可以使用键盘快捷键和其他方法复制和粘贴数据。
4. 重启你的 Mac
如果在尝试上述故障排除修复后仍无法复制和粘贴，请重新启动Mac并再次检查。确保在重新启动Mac(Mac)之前关闭所有打开的应用程序，以避免丢失未保存的数据。
选择菜单栏上的Apple 标志，然后选择(Apple logo)重新启动(Restart)。
5.以安全模式启动
在安全模式下(Safe Mode)启动Mac可以帮助确定问题是否由损坏或粗略的第三方软件（扩展、启动程序、字体等）引起。
以安全模式(Safe Mode)启动的步骤因设备的硬件配置而异——基于 Intel 的 Mac 或基于Apple Silicon 的Mac(Macs)。我们创建了一个详细的教程，涵盖如何在安全模式下启动和使用 Mac(boot up and use Mac in safe mode)。
以常规模式重新启动您的Mac，并检查复制和粘贴现在是否正常工作。
6. 更新或降级你的 Mac
macOS 主要升级的第一个版本通常带有最严重的错误和问题。复制(Copy)和粘贴故障是macOS Big Sur 的最大问题(biggest problems with the macOS Big Sur)之一。
(Some Mac users)一些最近升级到 macOS Big Sur的(Big Sur)Mac 用户在使用Finder时无法在上下文菜单中找到“粘贴”选项。此后， Apple(Apple)发布了修复此问题的更新。更新您的Mac并检查是否可以解决问题。
打开System Preferences，选择Software Update，然后安装页面上可用的任何更新。
如果您的Mac是最新的，但粘贴功能仍未显示，请回滚到稳定版本的操作系统。本关于降级 macOS 的教程包含您需要了解的有关在(tutorial on downgrading macOS)Mac上回滚更新的所有信息。
(Reset your Mac’s NVRAM and SMC)如果此处未列出任何潜在修复程序，请重置 Mac 的 NVRAM 和 SMC ，恢复Mac上的复制和粘贴功能。请访问附近的Genius Bar 天才吧(Genius Bar)或授权的Apple 服务提供商(Apple Service Provider)，以对您的 Mac 进行维修或维修(have your Mac serviced or repaired)。
Copy and Paste Not Working on Mac? 6 Fixes to Try
Can’t copy or paste fіles, texts, and other items on your Mac notebook or desktoр? We’ll explaіn why that happens and recommend possible fixes for copy and paste issues in macOS.
Before proceeding, confirm that you’re using the correct key combinations assigned to copy, cut, and paste functionalities. As a refresher: “Command + C” copies data, “Command + X” cuts data, while “Command + V” pastes copied data.
These shortcuts may not work if there’s a problem with your Mac’s keyboard. Perhaps, certain keys aren’t working properly on the keyboard. If the hotkeys don’t work, try copying and pasting data from your Mac’s menu bar.
Select a file or text, select Edit on the menu bar, and select Cut, Copy, Paste, or Paste and Match Style.
You can also copy and paste data from the macOS context menu. Select and right-click (or control-click) what you want to copy, right-click or press control + click, and select Copy on the context menu. Head to the destination folder, app, or text field, and select Paste on the context menu.
Try the troubleshooting steps below if you can’t copy and paste on your Mac using any of these methods.
1. Force Close and Reopen Your Apps
If the problem is specific to a few Mac apps; force-quit and re-open the affected app(s). This refreshes the app and possibly restores the copy and paste functionality.
- Press Command + Space bar to launch the Spotlight Search. Enter activity monitor in the search box, and press return or select Activity Monitor.
Alternatively, go to Finder > Applications > Utilities > Activity Monitor.
- Select the affected app and select the Stop icon (the x icon) in the Activity Monitor toolbar.
- Select Force Quit on the confirmation prompt.
Repeat these steps for all affected apps. Relaunch the app(s) and check if you can copy or paste content.
2. Force Close the Pboard Server
“Pboard” stands for “Pasteboard.” The Pasteboard server is a crucial background process that plays a considerable role in copying and pasting data on your Mac. Pboard functions as macOS’ clipboard daemon—the temporary storage that holds and conveys copied data from the source to the destination folder or app.
Copy and paste may not work on your computer if there’s a problem with the pasteboard server. Force-quitting the process will clear your Mac’s clipboard, refresh the copy and paste functionality, and help set things back in order.
Force Close Pboard via the Activity Monitor
Terminate the pasteboard server in the Activity Monitor, wait for a few seconds, and try copying and pasting content when macOS automatically restarts the process.
- Head to Finder > Applications > Utilities and double-click Activity Monitor.
- Tap the search icon in the top-right corner.
- Type pboard in the search bar and double-click pboard in the Activity Monitor window.
- Select Quit.
- Select the Force Quit button.
Force Close Pboard via the Terminal
You can also kill system processes using Terminal in macOS. Here’s how to force close the pboard process using a Terminal command.
- Go to Finder > Applications > Utilities and double-click Terminal.
- Paste or type sudo killall pboard in the console and press return on the keyboard.
- Enter your Mac’s password and press return.
Close Terminal and check if you can copy and paste data across all apps.
3. Force Close the WindowServer
WindowServer is another system component that’s crucial to the functioning of the Mac operating system. Terminating WindowServer can help eliminate system-level glitches causing copy and paste not to work on your Mac.
We recommend closing all active applications and saving all ongoing work before force-quitting the WindowServer. That’s because the operation will log you out of your Mac, close all active applications, and refresh your Mac’s operating system.
All closed applications will automatically launch when you sign in to your Mac, but you may lose unsaved data.
- Open the Activity Monitor, enter windowserver in the search bar, and double-click WindowServer.
- Select Quit.
- Select Force Quit.
Enter your Mac’s password on the sign-in screen and check if you can now copy and paste data using keyboard shortcuts and other methods.
4. Reboot Your Mac
If you still can’t copy and paste after trying the troubleshooting fixes listed above, restart your Mac and check again. Ensure you close all open applications before restarting your Mac to avoid losing unsaved data.
Select the Apple logo on the menu bar and select Restart.
5. Boot in Safe Mode
Starting your Mac in Safe Mode can help determine if the problem is caused by corrupt or sketchy third-party software—extensions, startup programs, fonts, etc.
The steps to boot in Safe Mode vary depending on your device’s hardware configuration—Intel-based or Apple Silicon-based Macs. We created a detailed tutorial covering how to boot up and use Mac in safe mode.
Restart your Mac in regular mode and check if copy and paste now work without any issue.
6. Update or Downgrade Your Mac
The first version of major macOS upgrades usually ships with the worst bugs and issues. Copy and paste malfunction is one of the biggest problems with the macOS Big Sur.
Some Mac users who recently upgraded to macOS Big Sur couldn’t find the “paste” option in the context menu when using Finder. Apple has since released an update that fixed this issue. Update your Mac and check if that resolves the problem.
Open System Preferences, select Software Update, and install any update available on the page.
If your Mac is up-to-date and the paste functionality still isn’t showing up, roll back to a stable version of the operating system. This tutorial on downgrading macOS has everything you need to know about rolling back the update on your Mac.
Reset your Mac’s NVRAM and SMC if none of the potential fixes listed here, restore the copy and paste feature on Mac. Visit a nearby Genius Bar or an authorized Apple Service Provider to have your Mac serviced or repaired.
