当应用程序安装登录项时， (Item)Mac显示屏上会弹出“已添加背景项(Item)”通知。理想情况下，仅当应用程序在您的设备上安装其登录项时才会弹出此通知。但是，损坏的缓存文件和 macOS 错误可能会导致您的Mac反复显示“已添加背景项目(Item)”通知。
按照本教程中的故障排除提示停止 macOS 设备上的“已添加背景项目”通知。
更新您的 Mac
“已添加背景项目”通知在运行特定早期 macOS Ventura版本的(Ventura)Mac(Macs)上普遍存在。Apple 推出了 macOS Ventura 13.3，(Apple rolled out the macOS Ventura 13.3)以解决导致过多“添加背景项目”弹出窗口的问题。
如果您的Mac运行 macOS Ventura 13.2.1或更低版本，请更新到 macOS Ventura 13.3或更高版本。
前往System Settings > General > Software Update，然后选择立即更新(Update)或立即升级。
删除该应用程序作为登录项
登录项（或启动程序）(Login Items (or Startup Programs))是当您登录Mac时自动打开的应用程序。从Mac(Mac)的登录项(Login Items)中删除应用程序应该会阻止 macOS 显示该应用程序的持续“背景项已添加”通知。
假设您收到(Say)Zoom的“已添加背景项目”通知。停止Zoom应用程序与 macOS 一起启动应该会停止通知。
- 打开“系统设置”(System Settings)，选择侧边栏上的“常规” ，然后选择(General)“登录项目”(Login Items)。
- 在“登录时打开(Open)”部分中选择有问题的应用程序，然后选择减号(Minus)(–) 图标将其从列表中删除。
重新启动(Reboot)Mac并检查将应用程序作为登录项目删除是否会停止“已添加背景项目”通知
。(Mac)
关闭后台访问
您的Mac(Mac)是否显示特定应用程序的“已添加背景项目”通知？关闭应用程序的后台访问可能会阻止通知不断弹出。
禁用后台访问会阻止应用程序在未打开时执行任务（例如，下载更新）。
前往System Settings > General > Login Items，然后在“后台允许”部分关闭该应用程序。
更新或重新安装应用程序
对于过时的应用程序或与您的 macOS 版本不兼容的应用程序，您可能会不断收到“已添加背景项目”通知。从App Store(App Store)更新应用程序或从开发者网站下载最新版本。
(Delete)如果“已添加背景项目”通知仍然存在，
请删除并重新安装应用程序。
转至Finder > Applications，右键单击该应用程序，然后选择(Bin)移至(Move)Bin 。
我们建议您先删除应用程序的缓存数据和剩余文件，然后再将其重新安装到您的Mac上。
打开Finder，按Command + Shift + G ，在对话框中粘贴 ~/Library/Application Support ，然后按(Support)Return。
右键单击应用程序(Right-click)的(Bin)文件夹并选择移至(Move)Bin 。
重新打开“转到文件夹”框（Command + Shift + G）并删除这些目录中的应用程序文件夹和属性列表(Property List)（.plist）文件：
- 〜/库/缓存
- 〜/库/首选项
- 〜/库/保存的应用程序状态
- /库/LaunchAgents
- /库/LaunchDaemons
删除 LaunchAgents 文件夹 (/Library/LaunchAgents) 中的 .plist 文件对某些 Mac 用户(some Mac users)来说非常有效。
重新启动(Reboot)Mac并从App Store重新安装应用程序，或从开发人员网站下载应用程序的软件包文件
。(Mac)
重置登录(Reset Login)和后台项目数据(Background Item Data)
您还可以通过重置Mac(Mac)的登录和后台项目数据来停止“已添加后台项目”通知。关闭不断向Mac(Mac)添加背景项目的应用程序，然后按照以下步骤操作。
- 转至Finder > Applications > 实用程序(Utilities)，然后双击Terminal。
- (Paste)将sfltool resetbtm粘贴到终端(Terminal)窗口中，然后按Return。
- 输入 Mac 的密码或在出现提示时使用 Touch ID。
- 当您看到“数据库(Database)重置”成功消息时，关闭终端(Terminal)窗口并重新启动Mac。
不再有烦人的通知
这些故障排除提示应该会停止不断出现的“已添加背景项目”通知。如果尝试这些修复后通知仍然存在，
请联系 Apple 支持(Contact Apple Support)或访问附近的Apple Store 。
How to Stop/Disable “Background Items Added” Notifications on Mac
A “Background Items Added” notification pops up on your Mac’s display when an appliсation іnstalls a Login Item. Ideally, this notification only pops up when an application installs its login item on your device. However, corrupt cachе files and macOS bugs can cause your Mac to display the “Background Items Added” nоtificatiоn repeаtedly.
Follow the troubleshooting tips in this tutorial to stop the “Background Items Added” notification on your macOS device.
Update Your Mac
The “Background Items Added” notification is prevalent on Macs running specific early macOS Ventura versions. Apple rolled out the macOS Ventura 13.3 to resolve issues causing excessive “Background Items Added” pop-ups.
If your Mac runs macOS Ventura 13.2.1 or older versions, update to macOS Ventura 13.3 or newer versions.
Head to System Settings > General > Software Update and select Update Now or Upgrade Now.
Remove the App as a Login Item
Login Items (or Startup Programs) are applications that open automatically when you log in to your Mac. Removing an app from your Mac’s Login Items should stop macOS from displaying constant “Background Items Added” notifications for the application.
Say you’re getting the “Background Items Added” notification for Zoom. Stopping the Zoom application from starting alongside macOS should stop the notification.
- Open System Settings, select General on the sidebar, and select Login Items.
- Choose the problematic app(s) in the “Open at Login” section and select the Minus (–) icon to remove it from the list.
Reboot your Mac and check if removing the app as a login item stops the “Background Items Added” notification.
Turn off Background Access
Does your Mac display the “Background Items Added” notification for a specific application? Turning off background access for the app might stop the notification from constantly popping up.
Disabling background access stops the app from performing tasks (e.g., downloading updates) when it isn’t open.
Head to System Settings > General > Login Items and toggle off the app in the “Allow in the Background” section.
Update or Reinstall the Application
You might get constant “Background Items Added” notifications for outdated applications or apps incompatible with your macOS version. Update the application from the App Store or download the latest version from the developer’s website.
Delete and reinstall the application if the “Background Items Added” notification persists.
Go to Finder > Applications, right-click the application, and select Move to Bin.
We recommend deleting the application’s cache data and leftover files before reinstalling it on your Mac.
Open Finder, press Command + Shift + G, paste ~/Library/Application Support in the dialog box, and press Return.
Right-click the application’s folder and select Move to Bin.
Reopen the “Go to Folder” box (Command + Shift + G) and delete the application’s folders and Property List (.plist) files in these directories:
- ~/Library/Caches
- ~/Library/Preferences
- ~/Library/Saved Application State
- /Library/LaunchAgents
- /Library/LaunchDaemons
Deleting .plist files in the LaunchAgents folder (/Library/LaunchAgents) worked the magic for some Mac users.
Reboot your Mac and reinstall the application from the App Store, or download the application’s package file from the developer’s website.
Reset Login and Background Item Data
You can also stop the “Background Items Added” notifications by resetting your Mac’s login and background item data. Close the application that keeps adding background items to your Mac and follow the steps below.
- Go to Finder > Applications > Utilities and double-click Terminal.
- Paste sfltool resetbtm in the Terminal window and press Return.
- Enter your Mac’s password or use Touch ID when prompted.
- Close the Terminal window and reboot your Mac when you see a “Database reset” success message.
No More Pesky Notifications
These troubleshooting tips should stop the constant “Background Items Added” notifications. Contact Apple Support or visit a nearby Apple Store if the notifications persist after trying these fixes.
