MacBook Air :: System Making A Strange Noise / Loud High Pitch Whine
Jun 18, 2008
Hey guys, got a little issue here. I have had a MBA since about march of this year. Just recently I on two occasions the computer has all of a sudden had this loud high pitch whine. It has only happened twice and at both times (if I remember the 1st time correctly) I wasn't really doing anything on the computer. Today specifically it was just sitting idle on my desk. Not sure where its coming from maybe speakers? Any idea to what this is? Should I be setting up an appointment to see a Mac Genius?

I have a June 2010 17" 2.66 i7 UMBP. This is going to sound really silly and I do not really know how to describe it correctly, but it has begun to make lots of strange "Tapping/Clicking" noises. It happens quite regularly when the notebook is stationary but increase whenever the notebook is moved.
I am familiar with the hard drive clicking noise but this is totally different - it kind of sounds like a small metal ball-bearing inside a small, thin glass sphere knocking or clicking against it's side or like tapping a small thin glass object with something like a thin metal rod.
I am sorry for the poor description but that is the best way I can describe it & know I must sound like a complete idiot but I am not very savvy to computer issues but I hope someone can identify what these noises are if if they mean that something bad is going on.

ive had a look around an only found bits an pieces relating to this but nothing really specific.i have an imac 3.06ghz, 4gb memory. less than a year old its been making some noises recently (like a downloading sound for afew seconds every so often) which happens every 30 seconds or so. this happens even when theres no programs open and im not connected to the internet!!! ive only really noticed it doing this the last month or so to be honest.
the computer has also been re-formated about a month ago as it was passed onto me from a family member, an im wondering if its got anything to do with that?is this a normal thing for macs an maybe i just havent noticed it before, or does it sound like something is wrong??

I have a Macbrook Pro, one generation old. In the past week, it started making a high pitched noise from the upper left hand corner, near the keyboard. When I pick the computer up and change the angle, I can eliminate the noise.
Just in the past day I noticed that in addition to this high pitched noise, periodically a much louder, different noise comes from the same area, which again, if I move the computer around, I can minimize the noise.
My guess is that there is something loose in the computer, maybe a fan? Should I bring it to apple? My computer has been running pretty slow lately, could this have anything to do with it?

I've noticed on my MacBook Pro (late 2013 with retina, 13", 2,4GHz i5, 256GB SSD, 8GB Ram) that when I run the display on low brightness, there is a high pitch noise coming from the screen (inverter problem)? It seems as it disappears when adjusting to either a high brightness or turning it to zero.
Info:
MacBook Pro with Retina display, OS X Mavericks (10.9.4)

I have been presented with an iMac G3 400Mhz. It has an annoying loud whine. The whine is constant and high pitched. I am thinking exhaust fan. Is my thinking correct? Is it hard to get to and replace?

This is my first post, and I apologize as it's a little long. I just wanted to get the whole story on the table and clarified.I've had one of the new Aluminum 13" MacBooks (2.0GHz C2D) since Christmas Eve. A few weeks ago, it accidentally fell off my desk at work (not a far drop , but far enough for my heart to stop for a few minutes) when I got tripped up in the power cord under the desk.
For all intents and purposes, the MacBok seemed to work fine. I had one of our IT staff, who happened to be a trained Apple repair tech, take a look at it; the only real damage was that the display hinge had been knocked a little out of alignment. Just ot be on the safe side, I took the machine to the Apple Store, where they told me not to worry about attempting to get the hinge fixed (because I'd be paying a lot of money for such minor work), and the Genius sold me a hardcover plastic Speck case for the MacBook.
While the Speck case certainly looked nice and madethe already sturdy laptop feel sturdier and "protected", I was a little concerned about the amount of heat the machine was giving off within the case. On Sunday, I unplugged the machine from the MagSafe charger for a few hours and left it closed in sleep mode. When I woke it back up, the fan on the left continually gave off some sort of high-pitched whine whenever the computer was in idle mode.
I Googled, searching this site and others, and read about the "CPU whine" in the previous generation MacBooks and MacBook Pros. I also saw where a few people with new Aluminum MacBooks were having this same issue or something similar:
URL
It seems to only make the noise when the computer is running off of the battery - plugging in the MagSafe charger makes the noise quiet 85% of the time (I've found that plugging, unplugging, and replugging will not stop the whine from occurring).
I tried installing QuietMBP as was recommended in some posts, but the only setting that will stop the computer from whining is the "highest" setting (that is, allowing the processor 0 seconds of idle time), which causes QuietMBP to eat up 30% of my processor usage in Activity Monitor and to start the fans going (and, presumably, to significantly lower my battery life).
I don't know whether all of this was the result of the MacBook falling, from it overheating in the case, or something that "just happened". I set up an appointment with the Genius bar for today at 4 PM, but Idiscovered another odd occurance when I set up a new account for the Apple Store (rather than give them my password)
The noise never happened under the new account. Never. I left the machine idle until any and all initial processes were done. No noise. I checked Activity Monitor for stray processes. None. And no noise.
Now I'm bewildered. Could something have gone wrong somewhere in my account, leading to a corruption of a power management utility or process? I'm not canceling my appointment, but I am going to try a few things before I leave. I've already repaired disk permissions, and I'm about ot reinstall the 10.5.6 OS X combo update. Should I try to reset the PRAM too? What other options should I be looking at?
Or should I just wait, and let the Genius Bar folks look into it? As a note, I'm aware I may have to pay for any repairs because they may or may not blame them on the MacBook having dropped (despite two to three weeks passing between the fall and this issue arising), and I'm okay with paying for reapirs (though I will try my best to argue my case, of course).

I just bought a pair of the Rokit 5 external speakers. When I plug them into a Mac Pro (Tower) I get a high-pitched hum from the speakers each time I try to play a sound. So if I go into System Preferences/Audio, and I try to play a sound, the high-pitch is heard as the sound plays, and for a second or two after, then it goes away, and is heard again each time I try to play a sound. Same with when I play something thru iTunes or any of my audio apps.
If do the exact same thing playing from a Macbook, I do not have that problem at all, the sound is nice and clear with no high-pitch sound.
I have the speakers plugged in using 1/4 inch jacks to an external sound card (MBox), and this audio card is plugged USB into the Mac.

I just bought my MacBook Pro last week. When I power it up, it makes a loud noise for about a second and a half. I think it's the hard drive starting up or the disc drive. I'm not sure which one, but it's pretty loud, so I was just wondering if anyone else noticed this and if it is normal.

Every time my trackpad is touched it makes a clicking noise/rattling noise. No, it is not coming from the speakers. It seems to originate from the bottom middle and the bottom left where I mostly click, but even when I scroll more upwards it makes the noise. This computer is in excellent condition and has never been dropped or anything.

My Macbook Air has suddenly decided not to turn. I have tried the rebook using the left hand side keys 'shift/control/option & power' but still nothing happens. Every now and again when I try turning it on using the power button the fan turns on and is really loud?

I am so upset right now, this is my 2nd macbook with this problem. I just got this macbook yesterday and the hard drive is making a clicking noise, but it isn't a click....click...click... like a lot of people have had, it's actually more of a quick series of clicks every few seconds, almost like the hard drive is shaking. It goes away for a bit when I am typing, like right now, but after I stop it comes right back.
Also the fan is pretty loud, considering I haven't put anything on the computer yet.. I've already been to the genius bar and all they did was give me a new, worse macbook, so there is no way I'm going back. Are there any fixes for a noisy hard drive aside from voiding my warranty and putting my own in? If it is normal, I might just invest in a good pair on noise cancelling head phones... Thanks!

My (new) iMac makes a strange noise when I boot. It looks like the hard disk to me. As long as it makes the noise, it doesn't boot. After the noise is gone (sometimes in a minute, sometimes five). I have attached a file recorded with my iPhone to illustrate what I mean. Is this normal or should I get back to Apple?

I have a new 27" I7 that appears to have the high pitch sound issue if the brightness is not at max or lowest. How "common" is this issue?
I do not need the perfect iMac (I have some gray banding and the 1TB HD grumbling and it is not a big issue to me) I just wanted to see if this high pitch noise is considered a defect and needs to be fixed/replaced or it is more common than not with the iMac.

My first generation unibody Macbook hasn't had any problems to this date but now it's constantly making that mechanical loading-like noise which is usually heard when the Macbook is switched on (the noise before the start up sound) or when the lid is opened to wake up the computer. Is there a fix to this?

I just received my new Mac Pro from apple on Saturday. This thing is a beast! I am planning on running apps from Final Cut Studio 3, Photoshop, After Effects, and others. 2.66 Quad/6GB RAM (OWC)/640GB HD/ATI 4870
I have a few questions.
1.) Is it normal for the Mac Pro's fans to make a lot of noise when you first start it up or wake it from sleep? My fans make a lot of noise for about 16 seconds or so.
2.) I am planning to put a second optical drive in it. Is there a way to eject only one tray at a time, or will it do both?
Now, I am selling my iMac for around $800 and I am looking at some upgrades:
An additional 21.5" Acer LCD display
A mini display port to dvi adapter
A LG blu ray burner
Two 1TB samsung internal HDs
A blu ray player (I do not have one yet)
Elgato Eye TV hybrid

I was out of town so this description was second hand but the computer has been running a little weird for a while. When I have too many apps open or on a website that has a lot going on...the computer starts revving up until I quit out of everything and let it slow down. I guess while I was gone, this happened but nobody quit out the apps and it eventually turned the screen black. When I tried restarting it sounds like the computer is working but the screen is black so I can't see if it is booting up or not. I took the monitor into the apple store yesterday and it started up right away for them. It's a cinema 23" I think.

Today, I got home and turned on my iMac 21.5 inch. On a typical day, I'd here the "BONG" and then everything would be normal. Today, my fans, or something inside the computer, sounded like it was going crazy. I have no idea what's wrong.

My family just recently upgraded from an old PC to this 27" iMac, during the early part of the summer. While using it over the last little while, I would notice a noise that sounded like a harddrive spinning or possibly some sort of a fan noise. The best way to describe it would probably be as digital noise. It's not incredibly loud, but it's a decent volume, and can get quite annoying. It has a little bit of a squeak to it.
Over the last little while, it's become more constant. When the computer is in use, it'll usually occur quite often. It's quite annoying and obtrusive when I'm watching videos and I'd like to know what it could be.I think our computer is still under warranty, so I'm hoping to find out if it is something wrong, so I can get it replaced.
I've also been wondering if it's a fan, or a regular noise. However, it's so constant that I'm starting to wonder. The other night, I was watching a video and it seemed like it was coming on every 30 seconds for a long span of time. We don't run any memory heavy programs on this computer. If anything, we're just using Firefox, iTunes and/or Messenger. Sometimes Office. There's little to nothing stored on this computer, as it's brand new, so most of its memory is free.

I have an older 15" powerbook Titanium. About five years old now. Been working pretty well all five years, save for an external hinge I had to replace. Last night, the computer started buzzing from the insides, a buzzing reminiscent of a distant chainsaw. The program i was working in (firefox) just went to the pinwheel of doom and never recovered. I moved to the finder, which did the same. I forced booted. Same noise. Same problems. I can use programs for a few minutes, but then they pinwheel of doom and the computer freezes out.

I just bought and received a new 21.5'' iMac and love it but the screen is making a high pitched noise, similar to a dog whistle. It's that sound that isn't loud but pierces through your brain. And the brighter the backlight is, the louder is gets. I love this machine but I don't think it should be doing this and it bothers the heck out of me. I called Apple and all they said was to bring it to the Genius Bar.

It happens when the MBP wakes up from sleep. The longer it sleeps, the louder it's. Listen for it after the 1st 10 second.

I've heard of people having issues with high pitched whining coming from the left-side of the keyboard due to the backlight inverter. There isnt much that can be done about it from what i've seen. My issue is slightly different, as I get the high pitched whine nearly at all times, and it changes dependent on the angle of the screen and level of backlight brightness.The biggest problem is that at certain points where the whining is happening, everything on-screen will freeze until Ive messed with the screen angle and played with the backlight buttons, then as soon as i've done that, it almost 'snaps out of it' and things on screen start happening again.

I know this happened before in the old Macbook Pros by the look of things when I searched around.Basically there is a noticeable high pitched whine when the screen brightness is either not completely off or max.

Whenever my screen is not turned up to the maximum brightness, a really high pitched sound is emitted from the laptop. If you've ever heard the "mosquito ringtone", that's basically what it sounds like. Really odd. It's definitely got something to do with the screen brightness, and I basically can't use my laptop at medium brightness because the sound drives me a little nuts. Turning the brightness to the lowest setting makes the sound less intense, but it's still audible.
