    I've been researching this issue and haven't seen many recent threads that address it. It seems no one has come up with a concrete answer in the earlier threads, so I wanted to ask again for the newer models.

    I have a MacBook Pro 13" that I got about 2.5 weeks ago. Today I noticed a sound when I moved it very slightly. It's the sound of a lightsaber. It's pretty worrisome, but I wasn't sure if I didn't notice it before (as I have loud kids) or if it just started.

    Could this sound be normal? Could it indicate something wrong?

    The hard drive seems to be okay when I run disk utility.

    Anyone with a similar issue?

    Thank you

    I'd say you got your money's worth if it sounds like a lightsaber.

    Jokes aside, it's probably a harddrive issue or more likely a fan issue.

    I have the same issue with my right fan, which makes a grinding noise if I move it too fast, what you can do is open up your computer, take some engine oil and grease up the fan, it'll work for about 4-5 months before it comes back.

    LOL, thanks for the response. Do you think it's worth taking it in? I did open it up today to upgrade my RAM. Didn't touch anything else. Hope I didn't muck up something. I'm not a newb to opening up computers, BUT this is my first MAC as I'm a PC tech. hehe

    Definitely lightsaber. I thought so and when I asked my daughter if she heard it, she said, "What? That lightsaber sound?" lol

    This is the weirdest thing ever. Does it glow and cut through things?

    Are there specific motions that are more likely to cause the sound, or is it simply caused every time you move it? Can you get a video with sound of this?

    Only glows in the dark. ;)

    When lifting it gently straight up, no sound.
    Tilting (gently) back or forth you get a sound. I doubt video would pick it up. It's VERY low, and I wouldn't have noticed had my kids been talking or if the tv was even on.

    No CD. I haven't used the drive at all. Sound does come from that side from what I can tell. But I think that's the side the hard drive is on as well. :confused:

    Seems to be the HDD or the fans fault.
    If it annoys you, take it to a genius and get it checked out

    When you guys say HDD, do you mean just a sound it makes or something wrong?

    Yeah, I'll likely take it in or I'll probably obsess over it. :D

    I have a 17in but never heard of "lightsaber" sound on my Mac.
    It might be a defect but Im not sure since I havent heard it.
    Is it possible for you to record it?

    Thanks.
    I think the sound is too low to record. I'll make an attempt though.
    Will update.

    It might be the sound of the fan. (like the airflow making the noise when fan is running) Im not sure though.

    Will be waiting on the update.

    Alright, when you listen you have to turn your speakers way up and get your head down close to them. It's low sounding on youtube, but sounded loud enough on my iphone. Oh well. Hope you guys can hear:

    That's awesome, it almost does sound like a lightsaber. My guess is the fan, as others have said. It's possible, but very unlikely, that it's the HDD.

    I certainly did. Today! I upgraded my ram to 8gb. I assume I know what I was doing since I was a PC tech for about 10 years. But, I've been known to screw up. LOL. I am hoping it's nothing I did. I didn't touch anything but a little metal to ground myself and then swapped out the ram.

    It does sound like it, doesn't it? Strange. I suppose I'll take it in to be sure. I'm so lazy. HAHA

    This is just a guess, but the fan might be damaged.
    I had a 2008 MacBook Air and I accidentally damaged the fan.
    After that it sounded like clicking and that "vroom" sound but way louder.
    Never thought it sounds like a lightsaber lol

    Try cleaning out the fan without scratching it or anything.
    The dust or something might be clogging/damaging the fan creating that noise.

    I totally forgot to update in case anyone else had the issue. My Mac is still going strong. I took it in that week I posted and they could find nothing wrong. Matter of fact, they claimed they couldn't even hear anything! Of course I didn't either, until I got home. So strange. I back up regularly, just in case. And yes, it still makes the sound when moved. LOL.

    I have this same issue on my 2011 Macbook Pro 13". Apart from that it works fine. Never any problems with it.

    I do have this issue on my 13" 2008 Pro. The sound is due to the hard drive and it particularly noticable on 'soft surfaces' such as a bed or sofa.
