Apple - Boot Into Safemode
Posted by John Woodard on 23 April 2014 02:47 PM

Background Information

Safe Mode starts your Mac and basic checks and disables some of the normal startup programs/preocesses.

Starting up in Safe Mode

To start up into Safe Mode (to Safe Boot), follow these steps.

  1. Be sure your Mac is shut down.
  2. Press the power button.
  3. Immediately after you hear the startup tone, hold the Shift key.
  4. The Shift key should be held as soon as possible after the startup tone, but not before the tone.
  5. Release the Shift key when you see the gray Apple logo and the progress indicator (looks like a spinning gear).

After the logo appears, you should see a progress bar during startup. This indicates that your computer is performing a directory check as part of Safe Mode.
To leave Safe Mode, restart your computer without holding any keys during startup.
