When you install OS X Yosemite, you can choose whether to encrypt your startup disk using FileVault. If you encrypt your startup disk, you must log in to your account whenever your Mac is restarted or wakes from sleep.
VoiceOver is not available from the FileVault login window. Depending on your computer, a series of beeps or spoken phrases indicate where the pointer is positioned in the login window.
- After your Mac wakes up or starts, determine if the FileVault login window is displayed by pressing Command-F5.
- If you hear "Username" or a single beep, then the cursor is positioned in the Name field and you can begin logging in. Continue to step 2.
- If you don’t hear any speech or a single beep, the FileVault login window might not be displayed yet. Wait a moment, then press Command-F5 again. If you still don’t hear a beep, your Mac may have encountered an issue setting up encryption. Turn off your Mac and then turn it on again. An unencrypted login process should begin where VoiceOver is available.
- Type your account name, and then press Return.
- If you hear 'Password' or a double beep, you entered a valid account name. Continue to step 3.
- If you hear 'Username' or a single beep, you entered an invalid account name and the cursor remains in the Name field. Keep entering your account name until you hear a double beep.
- Type your account password, and then press Return.
- If you hear three beeps, you entered a valid password and login proceeds.
- If you hear "password" or a double beep, you entered an invalid password and the cursor remains in the Password field. Keep entering your password until you hear three beeps.
