I follow the instructions in http://support.apple.com/kb/ht1455 to boot in Safe Mode, but it appears something different happens with Lion. After holding the shift key when hearing the startup tone, the icons for the two accounts I have configured come up as usual. If I hold the shift key after logging in, the screen stays grey and a status bar appears with a "sunburst" waiting animation. (I don't know what the canonical name for that is.) After the status bar fills, the waiting animation continues and then my MBA reboots.

How do I boot my MacBook Air (running Mac OS X 10.7.1) in Safe Mode?

If I boot my MacBook Air goes off after few second. I have tried to put on several times, it keeps going off after few second. Any help, I will appreciate –  user28850 Sep 10 '12 at 12:36

In my 2011 MacBook Air running Lion, when I select Restart... from the menu, if I then hold the shift key through the restart process, the boot process is distinctly different than a normal reboot. There is a progress bar across the bottom of the screen, and then I am deposited at the login window, despite normally automatically logging in. I suspect that a Safe Boot has indeed been performed. The difference between this an Safe Boot in previous versions is that no "Safe Mode" text appears on the login screen for me.

How can you tell that a Safe Boot has been performed? –  Daryl Spitzer Sep 8 '11 at 2:36
    
Do you have more than one account or do you have automatic login disabled? Or does it boot right into the Finder? –  Daryl Spitzer Sep 8 '11 at 2:37
    
I have one account, with automatic login enabled. But when I booted with shift held down, I got the login window. I don't have any explicit indication that a safe boot occurred, but the progress bar and the login window don't usually show up, and they did in this case. –  Daniel Lawson Sep 8 '11 at 3:07
