Mac startup shortcuts

less than 1 minute read

Because I keep forgetting them, here’s a list of buttons you can press during a Mac’s boot to change behaviour:

Key Action
C boot from CD or DVD
N Attempt to start up from a network server (NetBoot)
T start up in FireWire target disk mode
X force Mac OS X startup
Shift boot into safe mode
Mouse button eject CD before booting normally
Command-S boot into single user mode
Command-V verbose boot
Option choose startup disk at boot time
Option-Command-Shift-Delete Bypass primary startup volume and seek a different startup volume (such as a CD or external disk)
