How to Start Up iMac 2009 in Safe Mode

Starting up into Safe Mode does several things that can help resolve software or directory
issues that may exist on the startup volume. To start up in Safe Mode:

1. Shut down the computer.

2. Press power button.

3. Immediately after you hear startup tone, press and hold Shift key.
Note: The Shift key should be held as soon as possible after startup tone but not before.

4. Release Shift key when you see the screen with a gray Apple and progress indicator (looks
like a spinning gear). Note that booting into Safe Mode will take longer than a normal
startup. During startup, the words ”Safe Boot” will appear on Mac OS X startup screen.

5. To leave Safe Mode, restart computer normally, without holding down any keys during
startup.

We’ll show you how to quickly access the command line while a Mac is booted into Recovery Mode. For some quick background, on a normally booted Mac, the Terminal application is found within the /Applications/Utilities/ folder, and it can be accessed directly through the folder hierarchy or by using Spotlight to search for and launch Terminal app. But Recovery Mode does not have the same applications directory access, nor does it have Spotlight or Launchpad.
