    Basically what the title says...starting yesterday, my MBA will occasionally display a white rectangular outline when waking from sleep and at the same time produce a "zip/crackle" sound. It doesn't effect my performance, but it is a bit annoying and I am worried if something is wrong - software or hardware? I can provide a list of apps that I have installed so far, but no photos because the issue happens at random. Any help is much appreciated!

    Yes, but I'm more concerned about the brief white rectangular outline flicker.

    Managed to get a photo, sorry for the horrible quality.

    Anyone? I really hope its just a software issue, not a driver one.

    EDIT: I've done the Apple Hardware Test, and it gave me a perfectly fine result.

    Do you still have it under warranty? If so, I would just call apple and see what they say. They're super helpful and could probably tell you what is going on with it.

    As long as it's not acting up in any other way I wouldn't worry about it though.

    It's the new MacBook Air 13 inch i5/8GB/256 model. It's 8 weeks old, does that mean its still covered under warranty? I plan on updating to Mavericks and hope the problem goes away.

    The warranty is for 1 year without AppleCare.

    So after weeks of the problem persisting, I deleted a few suspicious apps, reverted some settings to their default, and the problems gone!

    :)

    I have the exact problem. Does this happen to you anymore? I restarted the pc and now it is fine, but I don't know if it will happen again.
