Keyboard shortcuts during OS X boot sequence
Posted by: drax in admin, osxNo tag for this post.
Here is a list of keyboard shortcuts or hotkeys available during the boot sequence of OS X on Intel based macs although some shortcuts also work on PPC.
Shamelessly ripped off apple’s documentation article:
Startup key combinations for Intel-based Macs.
| Keystroke | Description |
|---|---|
| Press C during startup | Start up from a bootable CD or DVD, such as the Mac OS X Install disc that came with the computer. |
| Press D during startup | Start up in Apple Hardware Test (AHT), if the Install DVD 1 is in the computer. |
| Press Option-Command-P-R until you hear two beeps. | Reset NVRAM |
| Press Option during startup | Starts into Startup Manager, where you can select a Mac OS X volume to start from. Note: Press N to make the the first bootable Network volume appear as well. |
| Press Eject, F12, or hold the mouse (/trackpad) button | Ejects any removable media, such as an optical disc. |
| Press N during startup | Attempt to start up from a compatible network server (NetBoot). |
| Press T during startup | Start up in FireWire Target Disk mode. |
