To disable auto-start apps on a Mac, you can follow these steps:
1. *System Preferences:*
Click on the Apple menu in the top-left corner of your screen.
Select "System Preferences."
2. *Users & Groups:*
In the System Preferences window, click on "Users & Groups."
3. *Login Items:*
You'll see a list of user accounts on the left side of the Users & Groups window. Select the user account for which you want to disable auto-start apps.
Click on the "Login Items" tab, which displays a list of applications that open automatically when that user logs in.
4. *Remove Unwanted Apps:*
In the Login Items list, you'll see a list of applications with checkboxes next to them.
To prevent an app from launching at startup, simply select it by clicking on its name.
Click the "-" (minus) button below the list to remove the selected app from the login items.
5. *Add or Enable Items (Optional):*
To add an application to the list of login items (if you want it to start automatically), click the "+" (plus) button below the list.
Browse to the application you want to add, select it, and click "Add."
6. *Restart or Log Out:*
Changes will take effect the next time you log in or restart your Mac. You can either log out of your user account or restart your computer for the changes to apply.
After following these steps, the selected applications will no longer start automatically when you log in to your Mac. You have control over which apps are allowed to auto-start, which can help improve startup times and system performance.
