Too many login items slow down your Mac's boot time. macOS Ventura reorganized startup management under a new System Settings location.

View Login Items

Go to System Settings > General > Login Items. Here you see apps that open at login and background services.

Remove an Item

Select the item and click the minus (-) button to remove it.

Via Terminal

osascript -e 'tell application "System Events" to get the name of every login item'

To remove an item by name:

osascript -e 'tell application "System Events" to delete login item "AppName"'
