To close the application that starts up automatically on your Mac, you can use the following methods: 1. Enter the "Login item" in "System Settings", select the target app and click the minus sign (–) to remove it; 2. Open the preferences of the corresponding app and uncheck the "Start-up" option; 3. Use terminal commands to view and delete the .plist file in the LaunchAgents directory to process hidden startup items; 4. Use tools such as LaunchControl, CleanMyMac X, or AppCleaner to assist in managing startup items. The above methods range from simple to traditional, and are suitable for different scenarios. Usually, the system settings are preferred to solve the problem.

Some applications on Mac will automatically start when they are powered on, which is really annoying, especially those programs that you don't use frequently but open by default. If you find that an app always pops up on your own when you turn it on, you can actually turn it off in several simple ways.

1. Close the login item in the system settings

This is the most direct way to work for most applications that will launch with the system:

• Turn on System Settings or System Preferences
• Find Users & Groups or Login Items
• After clicking in, you will see a list of all the apps that are automatically enabled.
• Select the one you want to disable, click the minus sign (–) button to remove it

Some software may still be here after uninstalling and can be cleaned up easily.

2. Turn off the self-start option inside the application

Many apps themselves also provide switches for whether to turn on or start, such as WeChat, DingTalk, Chrome, etc.:

• Open the App
• Go to Preferences or Settings
• Find options like "Open at Login" and "Start with system"
• Uncheck it

This method is cleaner because some apps are recognized as login items by the system, and are actually added through their own settings.

3. Use terminal commands to handle hidden startup items

Sometimes you will find that an app will start even if it has not been added to the login item. This may be because it registers the launchd daemon. You can try using the terminal to view and delete:

• Open Terminal
• Enter the following command to view the current user's startup item:

   ls ~/Library/LaunchAgents

• If you find suspicious .plist files, you can use the rm command to delete them (replacement is recommended before operation)

Of course, this method is a bit technical and is not recommended for beginners to operate at will.

4. Third-party tool-assisted management

If you don't want to move the command line or flip the settings one by one, you can use some lightweight management tools to view and control the startup items in a unified manner:

• LaunchControl : Powerful, suitable for users who like fine control
• CleanMyMac X or AppCleaner : The interface is friendly, suitable for one-click management of ordinary users

These tools can help you quickly identify which apps are added secretly and can also be operated in batches.

Basically these are the methods. Most of the time, you can do it by using the first system settings, but if you encounter stubborn background startup items, you have to check the application settings in depth or use tool assistance. The operation is not complicated, but it is easy to ignore the details. For example, some apps are still started when they are not in the login item. At this time, you have to go to its own settings to check it out.
