OS X :: Humming Sound Coming From Early Intel IMac?

Mar 31, 2009

There is a new humming sound coming from my parents iMac, I think it's the processor cooler but I'm not sure. It could be the hard drive as well, I just know it kicks up sometimes when there is a lot of activity. The problem is they don't do a lot on the computer so it scares them.

They are convinced that it is going to die because it's soo old, I think under two years, but this is the second computer they owned. The first was the first 20" G5 iMac that, instead of turning it off the correct way, they just unplugged from the wall outlet. Needless to say it died, but they think it was because their son in law used it too much. I try to tell them that it's because how they turned it off, but they didn't like their son in law, who is now an ex-son in law, so they blame it on him. Yes, I know, my parents are the last people to own a computer.

They also don't want to spend any money on their computer, so worse case scenioro, taking it to the Genius Bar without this computer being under warranty and having them replace the processor fan and/or the hard drive, what would it cost? I think it might just require a new fan for the processor cooler, but what if they need to replace a lot more?

May 29, 2012

The ivy bridge processors are coming out soon (or may already be out). I have heard that macbook pro 13" models might be able to use the new processers due to their lower energy useage. I presume that I will be able to take my mac to an apple store and have it installed. Is this information true?

Intel Mac :: No Input Sound Coming Through (External Microphone)

Apr 25, 2012

My external mike (Samson C01U, USB connection) isn't working; there's no input sound coming through. I'm certain it's not a hardware problem with the mike On preferences > sound, there's no sign of any input (with input volume level turned right up). Trying to record on Camtasia / Audacity / Quicktime also isn't giving any input.

Intel Mac :: Early 2009 To Sony Bravia KDL-52XBR9, Can't Get Video And Sound At The Same Time

Jun 23, 2012

I use a mini display port to HDMI to get the video and i use audio Y cable splitter for the audio.i can get video but not sound. If i disconnect the HDMI cable from the T.V. then i can get sound. If the HDMI cable and the audio cables are connected at the same time i can get video but no sound. I called Sony and according to them there is no setting on the T.V. that would help. My theory is that it's some kind of setting in the imac that prevents it from sending audio and video to the tv at the same time. Unfortunately i have not been able to figure it out.

IMac :: Computer Making Loud Constant Noise / Sound Coming After 30 Seconds

Nov 17, 2010

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.

Hardware :: Computer Making Buzzing/humming Sound - Fixing It?

Sep 1, 2008

I've had my imac for under two years, and just recently I noticed it making an odd humming/buzzing sound at times. It's not the normal sound you hear when your hard drive is working hard, it's definitely different. It's not the speakers either, it happens whether they are on or muted.

My suspicion may be that it has something to do with the power. That's because I've been bug testing a mac beta game, and it often crashes my computer, and I have to manually turn off my computer by holding down the power button until it cuts the power.

Does anyone know why this may be and how I can prevent it/fix it?

Software :: Sound Not Coming Properly / Sound Changes Automatically From Normal To High

Feb 9, 2009

I just bought an iMac 24" 2.8Ghz Dual Core, 2Gb RAM, 320 HDD. This nice iMac has been with me only 2 days and the problems already started. I don't know why when I play a song either in iTunes or in web(audio streaming) the audio suddenly changes. It's as if you applied an EQ and removed all the low frecuencies and after a few seconds the sounds returned just as normal. When this "auto EQ" happens, the sound becomes "brighter" (I hope you understand what I am trying to say) but just as I said, after a few seconds, the sound is played normaly. I am running Mac OS X v 10.5.2.

IMac :: External Speaker Sound Only Coming Out Of One Speaker?

Dec 21, 2009

I have a 2.1 Logitech Z4 setup, and the sound is only coming out of the left speaker. I have checked the wires, they are fine, and both speakers do work - but it could be the socket that's the problem. It's plugged into the line-in socket, I have put the output in System Preferences to Headphones, and everything is inserted correctly.

What do I do?

EDIT: My sound system is plugged into the headphones jack. I have tried putting headphones into the headphone jack and the sound also only comes out of the left earbud.

IMac (Intel) :: Grey Green Tint Over Entire Display / Early 2009 24 Inch

Jun 25, 2014

early 2009 Intel iMac 24". OS 10.6.8. 

Working in Excel today, I was highlighting groups of cells with color when the entire screen suddenly had a pale grey-green tint. Can still see colors beneath, but everything tinted (not just the Excel window, but the entire display). White, of course, is most dramatic. The Dell monitor beside it is fine. 

I've recalibrated color a half dozen times (have always had to do that to get the Dell and iMac screens as similar as possible). It's impossible to get white on the Mac.  Rebooted several times, including hard boot, zapped the PRam, ran Permissions Repair and Disk Repair from the startup CD. Installed Temperature Monitor to see if there's a heat problem, but I could not find normal temp values anywhere on the Web, so that was something of a bust. Temps attached below in case there's an educated set of eyes out there.... 

Ran some online tests, too, for color distortion, dead pixels, that kind of thing, but nothing reveled. 

I've been all over the Web looking for some guidelines, but most posts at apple and elsewhere seem to focus on later-model iMacs with the yellow lower screen problem when new (It's not that) or panic screens of wild colors, stripes, and the like. This is just a grey-green tint that covers the entire screen, rendering whites grey-green and colors muddy.

IMac :: 27" I7 With 2TB Hitachi Humming?

Sep 10, 2010

Last week I recieved my 27" iMac i7 2,93GHz with the 2TB Hitachi Drive.

I ordered this drive because it was said in this forum that this one should be silent.

Now, during access it is not really silent, but thats no problem

What bothers me more is, that there is a permament silent hum. An I can fell this vibration even on the stand (hopefully this is the correct term, I am from Austria, so english is not my native language).

And this vibration is also forwarded onto the table, but it is not really feelable on the table.

So my question is: Some say that their iMac is "dead silent". Mine isn�t, I also can here the fans silently, but that doesn�t bother me either. But this humming is somewhat distracting or annoying.

Maybe I am just to "picky", but do you really have iMacs which are almost inaudible?

Because I do not have any other problems I am not sure whether I should ask for a replacement.

IMac :: New 27" - Humming Normal?

Aug 16, 2010

My new iMac 27" (i3, 3.2GHz) is not so quiet as my previous iMacs -

I can hear a low humming noise! Not very loud, but I don't like it.

It grabs my attention...

It sounds like a fan motor or a transformer.

I can also feel a corresponding vibration.

Is this normal now? Does anyone else have this problem too?

Would you recommend to return/exchange this iMac?

IMac :: Fixing 27" Humming Noise?

Sep 19, 2010

After returning 4 21.5" imacs with yellow screens and hard drive noise, I decided to try a 27" and finally a beautiful screen with no problems, no hard drive noise. I was very happy...untill I started hearing a humming noise that sounds like it is coming from the power supply. The noise stops when I put it in sleep mode. I tried a bunch of things to determine if it was the fans or hard drive and that was not it. I am pretty sure it is the PSU humming all the time. This is the first imac with a perfect screen and now it is humming. I am so frustrated.

What should I do? Have the power supply replaced or return it for another one and take the chance of getting one with a yellow screen? I am still within my 14 days of original purchase date.

IMac :: 27" Humming - When Screen Dims

Nov 13, 2009

I bought iMac 27" from local apple store two days ago. Everything is fine execpt that there is some weird sound coming from the computer when the screen turns darker to save energy. Once I move my mouse to activate the screen, the sound goes away. I am saying the sound is so load, but it is still noticable and a little annoying in a quite room.

Update: I search "screem+humming+dim" and turn out actually a lot of iMac owners have this problem. Is it a technical issue Apple fails to resolve in general?

MacBook Air :: Sound Coming Out From It

Mar 31, 2012

I didn't play any music. Not beep sound or something similar. The sound comes from one side of the speaker. I closed all application but the sound is still there. Sounds like fan or something blowing inside. I ain't sure.  It stops only when I completely shut down my computer. When I switched it on, it's gone. My battery level is low (22%). Does this affect?

Intel Mac :: Making Constant Buzzing/humming Noise?

May 6, 2012

I purchased a 21" iMac a couple of months ago. Today it started making constant buzzing/humming noise. It's not really loud, but it is noticeable and annoying after a while. It stops if I put the computer in sleep mode or turn it off, but it starts back up  the moment I turn it back on again. It sounds like it is coming from the bottom of the screen near the speakers. I have tried adjusting the brightness and volume, but to no avail. I also tried lifting the computer off the desk to see if it was just vibration, but that did not make a difference either.

Intel Mac :: White 2006 Loud Humming Noise?

May 11, 2012

I have a 2006 White Intel Imac and I recently replaced the Superdrive with a non apple Panasonic Superdrive Model: UJ-85J-B from a used Acer Laptop.  The replacement drive has no sensor circuit board.  After putting it back together there was a loud humming noise and I assumed it was the new drive but when I took it out and started the Imac without it the noise remained?  Now I am thinking it is the fan just below where the Superdrive sits?  I blew out as much dust as I could from this fan and around the bottom of the case and that made the noise just a little less annoying.  It sounds like it is about to take off like an jet airplane?

MacBook Pro :: Different Hiss Sound Coming From My MBP?

Aug 24, 2010

I've read in several posts in this website's forum that there's a CPU noise problem with the MBPs, i even got to this site: o-noise-update...The thing is, that my computer is experimenting completely different symptoms, and that's quite annoying. I feel I'm alone in this The thing started like this, I sent my 13" Mid 2009's 2GHZ MBP to AppleCare to be repaired after the audio jack stopped working, they told me the audio card was to be replaced, and they did fix that problem, little did I not notice in the Apple Store (due to the store's natural noisy environment) that after this repair they gave me the computer back with the infamous hissing sound.
