What are startup apps on Mac?
Startup items (aka login items), are programs and services that run in the background when you boot up your Mac. Some may be added to the startup by yourself, while others may not have your permission.
Adding some startup items that are frequently used can improve your work efficiency, however, too many startup items running behind the scenes will eat up your MacBook's RAM, furthermore, resulting in your Mac running slow. Therefore, you must turn off those unwanted Mac startups.

How to turn off Mac login items in System Preferences
If you have too many Mac startup programs, using Mac Dock to look for each app and stop it could not be the best option. Instead, you can do it by using macOS System Preferences. You can find login items on macOS Ventura in System Settings.
- Select the Apple menu > System Preferences.
- Choose Users & Groups.
- Switch to the Login Items tab in the top center. The list of the enabled startup apps appears here.
- Click on an app you want to disable in the Login Items list.
- Select the minus icon (-) under the center pane to disable the app from startup.
- Repeat step 4 and step 5 for the rest of the unwanted Mac login items if you still have any.
Note: If you want certain apps to launch at startup without popping up on your Mac screen. You can tick the Hide box next to each app that is in the Login Items list. This ensures the program won't get in your way but will be ready to use when you need it.
If you're not sure what the app or program in the Login Items list is and are worried about whether its removal may cause some macOS problems, here is a way to help you identify an app that you don't recognize.
- Select the unknown or unrecognized application from the Login Items list and right-click on it.
- When the Show in Finder option appears, click on it.
- In Finder, right-click on the item, then select Quick Look from the context menu. This will bring a pop-up showing its version, size, and last modified date.
- If you need more information on the app, choose Get Info instead. Now, you'll see all the file attributes, such as the type of file, size, created date, last opened, and more.
After you've checked all related information regarding this unknown app or program, if you still can't decide whether to remove the app from opening up on Mac or not, we suggest you keep them in the Login Items list as long as the app is not malicious.
Mac startup programs are not in login items, how to remove them?
If you find Mac startup programs not in login items in System Preferences, it's likely due to launch daemons and agents hidden within your Mac Libraries. These files tell your Mac computer to launch programs independently of regular startup items. To find where those launch daemons and agents are stored and stop the programs from running at startup, use Mac Finder to help you.
- Launch Finder, and open Macintosh HD - the internal disk of your Mac computer.
- Select Library and look for folders named LaunchAgents and LaunchDeamons. As you can see, these files are .plist files that may be connected to a certain program or service.
- If you recognize a file name that matches a program you know continues opening from startup, you can delete it by moving it to Mac Trash. This action will stop the program from telling macOS it needs to be launched.
However, we don't recommend deleting every plist file you find unless you're 100% sure it's nefarious or unsafe. If you don't know what the plist file is used for, search its name online before proceeding with deletion. There are also LaunchAgents and LaunchDeamons folders within your Mac's System folder that you should not interfere with because your computer needs them to function properly.
