Temporarily Disable Login Items in Mac OS X
Login Items are applications and helpers that launch immediately when a user logs in to Mac OS X. These apps and utilities are easily adjusted and managed in system preferences on a user level, but you can also temporarily disable them on a per-boot and per-login basis if need be.
To stop the automatic login items in OS X on a temporary per-boot basis, you need to use a keystroke modifier at just the right time. This is slightly different depending on the status of password protection on the Mac, but the basic idea is the same.
