    Hi. I have been getting a quick white bright flash before the boot logo appears on startup and reset. I have done the pram and smc reset. Even wiped the dialed and reinstalled. And it still remains. Is this a bad sign? Boots fine to OS X. So I'm insure what's going on

    Many thanks.

    I'm guessing by the flash, you're talking about the one just after the boot chime, before the apple boot logo shows up. if thats the case then it's normal and there nothing wrong with your MB.

    Really!? I'm positive it never used to do that. I also don't get a chime??

    The white flash is really annoying and in your face. Like full on brightness. Surely that's not right.

    My friends MacBook Pro doesn't do the flash either...

    Thanks for your reply mate.

    I seem to recall this happening when 'startup disk' is not configured. The system blinks as it expects to go, then has to stop and look around for the correct drive. Boot with option key to respecify or visit your system prefs.

    Finally I am glad someone else has noticed this.

    My one day old MBA 2013 has this issue.

    It's not an issue, that just how the mac starts up.
