StartupItems

Mac OS X has actually two different notions of Startup Items, splitting up the notion of Mac OS 9 StartupItems in two concepts:

  1. System Services
  2. Login Applications

Services are started by SystemStarter.

1 System Services

Services are activated at boot time and don't feature a UserInterface. They are collected from these folders:

  • /System/Library/StartupItems
  • /Library/StartupItems)

To disable the System Services during startup, hold down the Shift key. Individual Services can be stopped or restarted using SystemStarter(8) (where supported by the startup script), instead of rebooting the whole system.

This resembles the SystemV scripts in /etc/init.d and multiple RunLevels activated by /sbin/init.

2 Login Applications

Each User can choose regular Applications to start automatically at login time, using the LoginItems PreferencePane.

To disable LoginItems, hold down the Shift key when submitting the login dialog. (verify?)
