Hello Daing Alwee,
Thanks for using Apple Support Communities.
For more information, take a look at:
OS X: What is Safe Boot, Safe Mode?
Starting up in Safe Mode
To start up into Safe Mode (to Safe Boot), follow these steps.
- Be sure your Mac is shut down.
- Press the power button.
- Immediately after you hear the startup tone, hold the Shift key.
The Shift key should be held as soon as possible after the startup tone, but not before the tone.
- Release the Shift key when you see the gray Apple logo and the progress indicator (looks like a spinning gear).
Have a nice day,
