When your Mac boots up, are you bombarded with a series of programs you didn't open and don't regularly use? Startup apps are convenient (when you actually need them) but the functionality is too often abused by developers desperate for you to use their product. These apps can eat up precious memory and slow down your computer. What's worse is many make it hard to even shut them down. The good news is that you can fight back. Here are several ways to take control of startup apps in macOS.
1. Temporarily Disable Startup Apps
Don't want to wait but aren't ready to permanently disable everything? You can temporarily disable startup apps. Enter your login information as you normally would, but hold down the Shift key on the keyboard before submitting your credentials. Continue holding until the Dock appears, and the startup apps won't load that time.
2. Disable Startup Apps
The simplest way to disable an app from launching on startup is from the Dock. Control-click on the app and hover over Options in the menu. Apps that are set to open automatically will have a checkmark next to Open at Login. Click that option to uncheck it and disable it from opening.

Instead of hunting for each app, though, you can do it all from one place from your user profile's login items menu. In macOS Ventura and higher, go to System Settings > General > Login Items & Extensions. Here, you'll see a list of apps set to launch on startup. You can remove any item in the list if you highlight it, then click the minus (-) button.

This ensures the program won't get in your way but will be ready to use when it's needed. Just tick the Hide box next to each app listed. Newer systems grant less control, but you can still disable certain apps under the Allow in the Background section.

If you still have certain programs opening when you boot up your Mac, it's likely due to launch daemons and agents hidden within your libraries. These files are usually in places you won't normally look and tell the computer to launch programs independently of regular startup items. They can even be used for nefarious purposes. You can find them in a number of places.
Open your disk drive in Finder—Macintosh HD by default—then open Library and look for folders named LaunchAgents and LaunchDeamons. They may also be separately stored within your computer's hidden files. Open Finder, click Go, and hold down the the Option key. Select the Library folder that appears and again look for LaunchAgents and LaunchDeamons folders.

If you see a file name matching a program that continues to launch on startup, delete it. This will stop the program from telling macOS it needs to be launched. You may also find files matching programs that are no longer installed; these can also be removed.
However, don't delete every .plist file you find en masse. If you don't know what something is for, look it up online before proceeding. There are also LaunchAgents and LaunchDeamons folders within the Mac's System folder that you shouldn't mess with because your computer needs them to function properly. If this all sounds too complicated, programs like CleanMyMac X, MacKeeper, and Nektony's App Cleaner & Uninstaller can do it for you.

If you like startup apps but want to avoid having them all open at once, programs like Delay Start and DelayedLauncher let you set a timer to control when they start up. Lingon can also help you open specific apps on a schedule.
