MAC OSX開機熱鍵

以下是外國網站的整理，出處有點忘了，希望對大家有點幫助。
• X = Force Mac OS X startup
• Option = Brings up a screen with startup volume choices (slow process, may take a while)
• Option+Command+Shift+Delete = Bypass primary startup volume and seek a different startup volume (such as a CD or external disk)
• C = Start up from a CD that has a system folder
• N = Attempt to start up from a compatible network server (NetBoot)
• T = Start up in FireWire Target Disk mode (very handy for plugging your Mac into another as an external hard drive)
• Shift = start up in Safe Boot mode and temporarily disable login items and non-essential kernel extension files (Mac OS X 10.2 and later)
• Command+V = Start up in Verbose mode.
• Command+S = Start up in Single-User mode
• Command+Option+p+r = Zap PRAM. Hold down until second chime.
• Command+Option+n+v = Clear NV RAM. Similar to reset-all in Open Firmware.
• Command+Option+o+f = Boot into open firmware
• Hold mouse button down = Force eject a CD/DVD

X= 強制使用Mac osx開機
C= 使用光碟開機
N= 網路開機，這個選項我沒用過，依內容所說，它會嘗試尋找可用的網路伺服器。
T= 用firewire外接硬碟開機，一般我都是從系統偏好設定中的啟動硬碟中選取開機硬碟，當然用這個也是可以啦。
不過當我外接硬碟插上去時，發現持續按著X也會切到firewire外接硬碟＠＠a，挺不解的。
shift= 安全模式
這些是比較常用的熱鍵，下面的就參考一下。另外補充一點，有時光碟卡在吸入式光碟機裡，那要怎麼退出呢？
在開機的時候一直按著touch pannel的單鍵滑鼠鍵＠＠，就會強制退出囉。
希望大家用apple用的愉快，如果有什麼錯誤的話請幫忙改正，謝謝囉！
