如何控制Mac啟動程序？

There are probably a few apps on your Mac that run in the background and come up when you start your computer. These are called startup (or login) items, and while they're meant to be convenient, some of them can be unruly.

It's easy to see that there are Mac startup programs that you would benefit from. For example, Calendars should sync in the background, and if you have an app that manages the health of your computer, it should also proactively launch when you start your device.

In this article, we'll tell you how to get rid of startup apps that Mac computers don't need, and give you a few ways to better manage your system.

What are Mac startup programs?

Mac launchers, also known as login items, are apps or processes that automatically launch when you sign in to a user account.

Why do these programs start automatically? Well, there are several reasons why they may be helpful to you:

• Convenience and saving time. Thanks to the startup programs' existence, you can use the apps you need immediately after logging in. It is especially true for programs that you regularly interact with. Imagine no longer having to manually launch them every time you log in! Convenient, right?
• Workflow optimization. Users often choose apps as launchers to create the most comfortable working environment. For example, if you constantly need to access your email or calendar, there is nothing better than setting them to automatically start when you turn on the computer.
• Background services. To ensure the productive work of some programs (even when closed), the constant presence of background processes is required. This category includes system utilities, background updates, or software components that are constantly running to support certain features.
• Notifications. Several apps require installation as startup programs to ensure timely notification delivery. It is typical for instant messengers, productivity tools, etc.

At first glance, such programs are helpful for faster and more productive computer work. But at the same time, an excess of unnecessary startup items slows down the computer boot time and consumes numerous system resources. Properly managing startup programs on Mac will help you avoid such problems.

Types of startup programs

As mentioned, on Mac, several types of launchers can start automatically when you sign in to a user account. It can be both basic system processes and numerous user apps. Let's take a look at the most common startup programs and find out what they are designed for.

1. System Services — iCloud, Notification Center, Bluetooth, Time Machine, etc. These are built-in macOS services and processes that provide basic system functions, namely, file indexing, cloud synchronization, remote device connection, backup, and receiving notifications.
2. Custom Apps — Mail, Messages, Dropbox, Calendar, Evernote, etc. They can be installed as startup programs to provide quick access to apps frequently used for work or personal purposes.
3. Background utilities — antivirus software, firewall apps, and system maintenance tools. These programs run in the background and protect the system, optimize performance, and more.
4. Cloud and synchronization services — Dropbox, Google Backup and Sync, and OneDrive. They automatically run to sync your files with your cloud storage, ensuring your data is up-to-date and available across all devices.
5. Apps for messaging and communication — Slack, Skype, etc. These programs allow you to stay connected with colleagues, relatives, or friends all the time.
6. Productivity tools — Todoist, Microsoft Office, and Google Workspace. They are used to efficiently manage tasks, projects, and documents, which can help improve the organization and productivity of the workflow.
7. Media and entertainment apps — iTunes, Spotify, VLC, Steam, etc. When auto-launched, they provide users immediate access to their favorite media and entertainment content.

How to manually stop Mac apps from opening on startup

You can change startup programs in another way, though it takes a bit more time. If you're okay with that, here's how to manage startup programs on Mac manually:

Remove and manage startup programs on Mac from the Dock

Are you looking for how to turn off startup programs Mac via Dock? Follow the steps below:

1. Run the app that you are going to remove from startup
2. Right-click on its icon in the Dock and click Options
3. Uncheck Open at login.

Tip: If you find your Mac's Dock a bit intrusive or cumbersome, you may like uBar. The Dock replacement for your Mac, uBar keeps things tucked out of the way, and shows you in a much better interface which apps are active and running on your Mac. It even has multiple-monitor support and status bars for apps running processes or downloading content.

Delay Mac startup apps

If you don't want to disable startup items, you may instead want to know how to edit startup programs Mac does not need immediately. An app named Delay Start can delay the start of apps at startup. This is a great option if your Mac is booting up slowly, but you still need apps to run in the background throughout your day.

It's also a nice app to keep in mind if you have a dedicated workflow. If you are a photo editor, you may want to delay the start of your photo editing software. If the first thing you do is import images from an external drive or camera, apps spinning up may interfere with the process. Rather than risk unintended consequences like lost images or damaged files, delaying an app's start may be the better workaround.

Remove daemons and agents from the startup process

You can check which daemons and agents are running on your Mac via the Finder app, but a word of caution: daemons and agents are hidden, which indicates you shouldn't alter them unless you have a very clear understanding of the repercussions it may have. So, tread lightly.

Here's how to remove agents and daemons via Finder:

1. In the Finder, click on the Go menu and choose Go to Folder. You can also use the Shift + Command + G key combination
2. Then type /Library/LaunchDaemons and press Enter

1. Scan the list of .plist files and search for anything with a name you don't recognize
2. If you see one, click on it and preview the file, looking for the name of a vendor you know
3. If you don't find one, drag the file to Bin

1. Then go to the Go to Folder (see step 1), type /Library/LaunchAgents, and press Enter
2. Next, repeat steps 3-5
3. Once you've dragged all the files you want to remove to Bin, empty it and restart your Mac.

FAQ

How do I access the startup menu on a Mac?

The Mac does not have a traditional "Start menu" like some other operating systems. However, you can access and manage the startup items (login items) that launch automatically when you sign in to your user account. These login items are responsible for launching apps at startup.

The fastest way to get rid of excessive startup programs is by using the app called CleanMyMac X. Install and open it on your Mac. On the left side of the window, select Optimization. Then choose which items you want to delete. Done. Alternatively, you can do that manually (Apple menu > System Settings > General > Login Items).

Why do programs open automatically on my Mac?

Programs open automatically on your Mac due to settings like Login Items and Startup Items, user preferences, background processes, and scheduled tasks. These automatic launches aim to provide convenience, timely notifications, and essential background services, but having too many startup items can slow down your Mac's boot time and use up system resources.

Is it OK to disable all startup items on Mac?

It is safe to remove startup apps from your Mac. You'll never run into problems when changing login items with the help of CleanMyMac X or in System Preferences. However, when you start deleting startup agents and daemons via Finder (Library Folder), it's possible to remove something you really need. Delete the wrong thing, and apps can become unstable or difficult to use.
