Bird 进程会占用 Mac 的CPU吗？该过程是否会减慢或冻结您的 Mac(freezing your Mac)？本教程解释了 macOS 中的 Bird 进程以及如何减少或降低其CPU使用率。
“Bird”在 macOS 中做什么？
Bird 进程有助于Mac计算机上的 iCloud 和 iCloud (Mac)Drive同步。它是负责将应用程序数据、文档和桌面文件同步到 iCloud 的后端进程。
Bird是一个轻量级系统守护进程，不断在后台运行，但在处理 iCloud 相关操作时最为活跃。正常运行时这是一个无害的系统进程。然而，在某些情况下，进程会出现故障，使用大量CPU，并降低Mac 的(Mac)速度。
如果 Bird 在Mac上同步 iCloud 数据时遇到问题，您可能会注意到 Bird 的(Mac)CPU使用率激增。在Mac(Mac)和 iCloud之间同步大文件时，后端进程也可能会消耗大量CPU。
如何减少 Bird 的 CPU 使用率
强制停止 Bird 进程、删除其缓存文件或重新启动Mac应该会减少其CPU使用率。重新启用 iCloud Drive并更新Mac操作系统也可以稳定 Bird 的CPU消耗。
强制退出小鸟
Bird 进程在Mac(Mac)计算机的后台持续运行。强制退出bird会刷新进程，并有助于稳定Mac上的CPU使用率。
- 打开Finder，前往Applications > Utilities，然后双击“活动监视器”(Activity Monitor)。
或者，按Command + Spacebar，在Spotlight 搜索(Spotlight Search)框中键入 Activity Monitor，然后选择Activity Monitor。
- 在右上角的搜索框中输入“bird”。
- 选择鸟进程并选择顶部菜单上的
停止(X) 图标。(Stop)
- 选择强制退出。
当您关闭或强制退出进程时，macOS 会自动重新启动 Bird。关闭(Close)并重新打开Activity Monitor，并检查强制退出 Bird 进程是否会降低其CPU使用率。
重新启用 iCloud 驱动器
关闭并重新启用 iCloud Drive(Turning off and re-enabling iCloud Drive)会从Mac中删除已存储在 iCloud 中的文件。我们建议您先备份Mac的 iCloud Drive文件夹中的文件，然后再重新启用 iCloud Drive。
您可以将 iCloud Drive文件备份到外部存储设备或Mac上的其他文件夹。
将您的Mac(Mac)连接到Wi-Fi，然后按照以下步骤重新启用 iCloud Drive。
- 打开“系统设置”(System Settings)并在左上角
选择您的Apple ID名称。(Apple ID)
- 在“使用 iCloud 的应用程序”中选择 iCloud Drive。
- 关闭同步此 Mac。
- 选择保留(Keep)副本以存储已备份到 iCloud 的文档。
等待几秒钟，让您的Mac关闭 iCloud Drive。在活动监视器中(Activity Monitor)检查(Check)Bird 的CPU使用情况，并在CPU消耗减少时重新启用 iCloud Drive。
- 再次打开“同步(Sync)此Mac”以重新启用 iCloud Drive。
- 轻点“完成”(Tap Done)关闭 iCloud Drive设置页面。
如果您的Mac运行 macOS Mojave或更早版本，请前往System Preferences > Apple ID，选择“iCloud”，然后取消选中“iCloud Drive”。等待几分钟，然后选中 iCloud Drive框以将其重新打开。
如果重新启用 iCloud Drive后 Bird 的(Drive)CPU消耗异常增加，请尝试下一个故障排除建议。
删除小鸟缓存文件
Bird 进程会在您的Mac上存储临时文件以加快其操作速度。但是，这些文件可能会阻碍其活动、增加CPU使用率，并且如果损坏，还会导致其他问题。
删除bird的缓存文件可以稳定其活动并减少其消耗的系统资源。请按照以下步骤删除Mac上的 Bird 缓存文件。
- 打开Finder并按Shift + Command + G打开“转到文件夹(Folder)”对话框。或者，选择菜单栏上的“前往”，然后选择“前往文件夹”(Folder)。
- 将 ~/Library/Caches/ 粘贴到对话框中，然后按键盘上的
Return 键。(Return)
- 找到 com.apple.bird 缓存文件夹。右键单击 com.apple.bird 并选择(Bin)移至(Move)Bin 。或者，将其移动到Mac(Mac)上的其他位置。
打开活动监视器(Activity Monitor)并检查删除bird的缓存文件是否可以稳定其CPU使用率。
删除 iCloud 帐户缓存文件
从计算机中删除 iCloud 帐户缓存文件也可以减少 Bird 的CPU使用率。
- 打开Finder，选择菜单栏上的“前往”，然后选择“前往文件夹”(Folder)。或者，使用Command + Shift + G快捷键打开“转到文件夹(Folder)”对话框。
- Paste ~/Library/Application Support/iCloud/Accounts/到对话框中，然后按键盘上的
Return 键。(Return)
- 将“帐户”文件夹中的文件移动到Mac上的其他文件夹。
如果bird的CPU(CPU)使用率没有变化或增加，
请将文件恢复到“Accounts”文件夹中。
重新启动你的Mac
在重新启动计算机之前关闭所有打开的应用程序，以避免丢失未保存的更改或数据。
选择Mac 显示屏右上角的Apple徽标，然后在Apple菜单中选择(Apple)“重新启动”(Restart)。
更新您的 Mac
在Mac(Mac)上安装最新的 macOS 更新可以解决系统进程和第三方应用程序的故障。
- 打开“系统设置”(System Settings)，选择侧边栏上的“常规” ，然后选择(General)“软件更新”(Software Update)。
- 选择立即更新。
运行恶意软件扫描
如果 Bird 继续过度使用CPU(CPU)资源，请检查您的Mac是否感染恶意软件。Avast Security、Malwarebytes、Bitdefender和Norton 360是适用于 Mac 计算机的最佳防病毒选项(best antivirus options for Mac computers)。
这些推荐的应用程序可以消除导致 Bird CPU使用率飙升的恶意软件感染。
剪掉鸟的翅膀
(Reset your Mac’s Non-Volatile RAM (NVRAM) and System Management Controller (SMC))如果 Bird 进程仍然使用大量CPU ，请重置 Mac 的非易失性 RAM (NVRAM) 和系统管理控制器 (SMC)。如果问题仍然存在，
请联系 Apple 支持(Contact Apple Support)或将您的Mac带到附近的Apple Store 零售店。(Apple Store)
What Is the “Bird” Process on Mac (and How To Reduce Its CPU Usage)?
Does the bird process hog your Mac’s CPU? Is the process ѕlowing down or freezing your Mac? This tutorial explains the bird process in macOS and how to reduce or reduce its CPU usage.
What Does “Bird” Do in macOS?
The bird process facilitates iCloud and iCloud Drive synchronization on your Mac computer. It’s the backend process responsible for syncing your app data, documents, and desktop files to iCloud.
Bird is a lightweight system daemon that constantly runs in the background but is most active when handling iCloud-related operations. It’s a harmless system process when operating normally. However, there are instances when the process malfunctions, uses a lot of CPU, and slows down Mac.
You might notice a spike in bird’s CPU usage if it has trouble synchronizing iCloud data on your Mac. The backend process could also consume a lot of CPU when syncing large files between your Mac and iCloud.
How to Reduce Bird’s CPU Usage
Force-stopping the bird process, deleting its cache file, or rebooting your Mac should reduce its CPU usage. Re-enabling iCloud Drive and updating your Mac’s operating system can also stabilize bird’s CPU consumption.
Force Quit Bird
The bird process constantly runs in the background on your Mac computer. Force-quitting bird refreshes the process and could help stabilize its CPU usage on your Mac.
- Open Finder, head to Applications > Utilities, and double-click Activity Monitor.
Alternatively, press Command + Spacebar, type activity monitor in the Spotlight Search box, and select Activity Monitor.
- Type bird into the search box in the top-right corner.
- Select the bird process and choose the Stop (X) icon on the top menu.
- Select Force Quit.
macOS automatically relaunches bird when you close or force-quit the process. Close and reopen the Activity Monitor, and check if force-quitting the bird process reduces its CPU usage.
Re-Enable iCloud Drive
Turning off and re-enabling iCloud Drive deletes files already stored in iCloud from your Mac. We recommend backing up files in your Mac’s iCloud Drive folder before re-enabling iCloud Drive.
You can back up the iCloud Drive files to an external storage device or a different folder on your Mac.
Connect your Mac to Wi-Fi and follow the steps below to re-enable iCloud Drive.
- Open System Settings and select your Apple ID name in the top-left corner.
- Select iCloud Drive in the “Apps Using iCloud.”
- Toggle off Sync this Mac.
- Select Keep a Copy to store documents already backed up to iCloud.
Wait a few seconds while your Mac turns off iCloud Drive. Check bird’s CPU usage in the Activity Monitor and re-enable iCloud Drive when its CPU consumption reduces.
- Toggle on Sync this Mac again to re-enable iCloud Drive.
- Tap Done to close the iCloud Drive settings page.
If your Mac runs macOS Mojave or older, head to System Preferences > Apple ID, select iCloud, and uncheck iCloud Drive. Wait a few minutes and check the iCloud Drive box to turn it back on.
Try the next troubleshooting recommendation if bird’s CPU consumption increases abnormally after re-enabling iCloud Drive.
Delete the Bird Cache File
The bird process stores temporary files on your Mac to speed up its operations. However, these files could hinder its activities, spike CPU usage, and cause other issues if they get corrupted.
Removing bird’s cache files can stabilize its activities and reduce how much system resources it consumes. Follow the steps below to remove bird’s cache files on your Mac.
- Open Finder and press Shift + Command + G to open the “Go to Folder” dialog box. Alternatively, select Go on the menu bar and choose Go to Folder.
- Paste ~/Library/Caches/ in the dialog box and press Return on your keyboard.
- Locate the com.apple.bird cache folder. Right-click on com.apple.bird and select Move to Bin. Alternatively, move it to a different location on your Mac.
Open the Activity Monitor and check if removing bird’s cache files stabilizes its CPU usage.
Delete iCloud Account Cache Files
Removing iCloud account cache files from your computer can also reduce bird’s CPU usage.
- Open Finder, select Go on the menu bar, and choose Go to Folder. Alternatively, use the Command + Shift + G shortcut to open the “Go to Folder” dialog box.
- Paste ~/Library/Application Support/iCloud/Accounts/ in the dialog box and press Return on your keyboard.
- Move the files in the “Account” folder to a different folder on Mac.
Restore the files to the “Accounts” folder if bird’s CPU usage doesn’t change or increase.
Reboot Your Mac
Close all open applications before rebooting your computer to avoid losing unsaved changes or data.
Select the Apple logo in the top-right corner of your Mac’s display and choose Restart in the Apple menu.
Update Your Mac
Installing the latest macOS updates on your Mac can resolve malfunctions with system processes and third-party apps.
- Open System Settings, select General on the sidebar, and choose Software Update.
- Select Update Now.
Run a Malware Scan
Check your Mac for malware infection if bird continues to overuse CPU resources. Avast Security, Malwarebytes, Bitdefender, and Norton 360 are some of the best antivirus options for Mac computers.
These recommended apps could remove malware infection responsible for bird’s CPU usage spike.
Clip the Bird’s Wing
Reset your Mac’s Non-Volatile RAM (NVRAM) and System Management Controller (SMC) if the bird process still uses a lot of CPU. Contact Apple Support or take your Mac to a nearby Apple Store if the issue persists.
