I have recently bought a new i7 27" imac and when the imac goes to slep it seems to crackle/buzz very very faintly.
I phoned apple who told me to do the following:
Turn off the imac.
Hold down ALT, CMD, and R, and then hold the power button.
Then still holding ALT, CMD, and R press the P key.
I've owned my iMac for a little over a year and I started having a weird buzzing noise coming from a hard drive fan. Downloaded iStat, everything runs at idle speeds (hard drive fan at 1200rpm), so the speed is not an issue. Sounds like a mechanical problem. Also downloaded FanControl, and once I increase the fan's speed to 2500rpm, the buzzing noise goes away, but now I can hear the fan It kind of defeats the purpose of having the expensive computer, that used to be virtually silent. I am in remote location in Alaska, where we don't have Apple store and the only way to fix is to ship it to mainland. Apple warranty is over, but I still get additional 1 year of coverage from Amex credit card, but I would much rather prefer to to fix it myself. Any suggestions on possibly replacing the fan myself? I am really debating whether I should ship it to Apple and trying to go through American Express with warranty. That would be complicated and I would end up without a computer for a few weeks.
Late 2008 iMac 24'. 3.06 GHz, 2GB RAM, 500GB Hard Drive, NVidia GeForce 8800GS.
I bought a second hand iMac G3 off eBay for a pretty good deal, and am trying to figure out where the buzzing is coming from.
It doesn't come with any CDs so I don't think I can do a hard wear test, but I've noticed it is happening even when the display is off, and is in sleep (although it gets less audible in sleep).
Another thing I noticed is that in OS X it will stop after a while of not using it, despite the screen being on and still showing the image, is this the hard drive stopping? When I go and touch a key or move the mouse it starts again.
How common is this? I prefer darker backgrounds and this may be an issue.I'm over the yellow and the buzzing, but this too? Don't take me the wrong way - I love my Macs but I can't say I'm crazy about this..See attachment. Ignore the image noise, the big spot that bothers me is on the top to the right.

A couple of years ago when I got a tv for my room, my dad built a rack of shelves into the wall, one for my tv, one for my stereo and one for random stuff. It's always been nice, but restricting. I like to move my room around, and My desk is forced to stay right next to that rack to transmit audio to my receiver via a hard wire. Seeing as my iMac has bluetooth built in, I was wondering if it is at all possible to send stereo high quality audio over bluetooth to some sort of receiver that would feed into two RCA plugs... Now, I'm not talking audiophile quality, this is just a $400 sony rig, no crown audio here, but I dont want it to sound like those old 900mhz wireless headphones with all the interference. Is this at all possible? Or am I doomed to either staying put, or running 5' of cable under my carpet?

View 16 Replies View Relatedjust purchased a new 27" Quad core i5 and it takes about 5 seconds for it to go to sleep, and then makes a loud noise after.
My hard drive is also noisy, it whines and drums constantly.
I also have got yellow tint on all sides of the screen.
I live in NZ so if i will not get a new replacement, instead it will be sent away to apple which will take forever
by the way it is the older 27" (late 2009) version.
Well, I have a late 2008 13" Macbook Aluminum, (I've had it since Christmas of 2008) and just yesterday, I noticed a weird buzzing-like sound coming from the inside of it. There's also a faint vibrating feel to it. I felt around, and the vibrating feels like it's coming from under the middle of the keyboard more severely. The buzzing occasionally sounds like it's getting faster, and then slower, faster, slower, etc.
View 10 Replies View RelatedI received my nice new Mac Pro yesterday. 2.66GHz With one 160gb drive and one 500gb drive and some other customisations which, for the purpose of this are not relivent.
My first and most serious problem is a rhythmic clicking, which according to technical support is a known issue and is to do with my hard disk drive. The noise comes from the top front side of the machine and clicks at around 200bpm at all times. It is very audible and unnexceptable and for this reason Apple are replacing my machine.
The second problem which I believe to be more of a design flaw is noisy fans. I obviously know fans make noise but this is an intermitent buzz, at a constant frequency. It sounds like a bee is flying about in my machine and varies according to the angle of the machine and wheither the superdrive bay is open.
As you will understand I am very dissatisfied. My machine took 3 weeks to arrive and is riddled with problems.
I noticed that when I move my MacBook Air when the fan is running, it makes a slight buzzing/grinding sound. Is this just air hitting the fan at a different angle or is it a bigger problem that needs to be fixed ASAP?

View 7 Replies View RelatedI was just downstairs in my basement using my macbook and I decided to come upstairs and when I got up here I noticed that my fan is making a weird buzzing noise. I can tell it is my fan because when I make the fans spin faster in smcfancontrol the noise gets louder. Could this be something that is in the fan or could this be a more serious problem? I can take the back case off and check but I just wanted to know if this could be a serious problem with the fan. Is there any chance I could have bent something by carrying it wrong?

About 5 mins ago i rebooted my Mac, and in the boot process something started to buzz horibly. I was in a dark room, so it was very scary for me and very late too... Being scared i pushed CTRL+OPTION+SHIFT+POWER so it shut down imeaditly.
I powered it on, no buzzing. But OS X did not boot at all. Just stood there. Now I'm booting of the recovery DVDto disable my EFI pass, so i can boot verbose.

I have had my MBA for almost a week, and I've had no issues so far. Until now. This is the case: The fan operates as it should. It stays on 2500 rpm at light use, and increases with heavier use. At 2500 rpm I was not able to hear it without putting my ear next to the keyboard. That was yesterday. Today the fan produces a new noise. It isn't very loud, but clearly audible at 2500 rpm in a quiet environment. It's a low, constant, buzzing kind of noise. It also increases with fan speed.

I have have never heard this before as it isnt that loud at all, and only cam across it by chance. I kind of figured out that it might be the electrical current.
View 1 Replies View RelatedI purchased my Macbook in August 2007 and have no problems until Christmas this year.
It started buzzing and I wasn't sure what it was, until a week later I got a folder with a question mark at log-in, from what I understand my hard-drive died. I replaced the hard-drive myself within a few minutes, very easy and no problems, and it runs perfectly.
It's been two weeks and it's already buzzing again. I take very good care of my Macbook but I do transport it from class and back everyday.
I just purchased the Macbook Air rev 2 120gb HD model. I it has the problems with the lines on the screen. It flickers on the one test image from the forums, but does not appear to flicker during normal usage. Also, it has a sort of CPU buzzing comming from the left side of the keyboard. It gets worse then I move the trackpad.
I was thinking of calling support on this, but I don't want to end up getting the same screen with the same problems. I was wondering if anyone has gotten any of this fixed. Is there some way that I can direct support so that they put in the correct model of screen.
My whitebook is making a buzzing sound that is coming from under the F4 and F5 keys, it can be heard a little with no background noise but when i put my ear close i can hear it much clearer. Does anyone elses macbook do this or does anybody have any idea what it is and should i take it to the apple store?

View 8 Replies View RelatedOver the past few months or so, I've been noticing a sound, much like a buzzing, coming from the left speaker area of my computer. It seems to be near the area where I plug in the charger. The sound is not terribly loud, but when it's quiet in my surroundings, it becomes quite evident. I'm not talking about an audio-related issue, but I am just unsure as to what may be causing the sounds and whether or not I should be worried.

View 3 Replies View RelatedYesterday I started up my MacBook Pro that I've only had for about 9 months. I immediately noticed that there was a barely audible buzzing / humming sound coming the inside of the laptop, most likely in the fans. I don't know how long this has been going on, and I really don't know the cause of it. So is this something I should be worried about (the sound is barely audible)? Or is this something that happens after prolonged use of the laptop?Â

My MacBook charger has always sparked a little when I plug it in (not every time, but often), which I've read is normal, but lately, I've also been getting a pretty loud buzzing sound both from the block and from the outlet. I have taken the disconnectable cord off the block, made sure all the connections looked clean, then made sure it was reconnected snugly, but I still have the problem. I've been having to unplug and replug from the socket several times to get the buzzing to stop (if it makes a difference, I always plug into the wall before I plug into the laptop, so the charger is plugged into nothing when I plug it into the wall. The sound starts as soon as the LED turns orange, and continues intermittantly, especially if I move the mouse. The block, itself, doesn't seem any hotter than normal). The cord is undamaged, but the prongs are a little scored up at the tips. It seems to happen more readily when the charge is below 65%. I did have water damage occur several years ago (I got lucky: The only problem I had was a messed up battery), but have had no other problems with my MacBook. I've only plugged it into an alternate outlet when the charge is above the 65% mark, and have gotten no noise from the other outlet, but can't say for sure if it's because it's a different outlet or if it's because my charge is above 65%.Â
I am planning on bringing it in to see if I can get my cracked palm rest repaired (if it's covered despite being out of warranty, which I have read/been told by a fellow MacBook owner that it is) and to see about upgrading to Lion, and I plan to have them check the cord and battery (Which no longer warns when it wants to be plugged in and is at 349 cycles), but I was wondering if this is something I should be concerned about, and to see if anyone else has had an issue with it.

Let me preface this by saying I am probably taking this to the Apple Store about an hour away from where I live tomorrow. For A while my MacBook Pro 13" has been making a loud spinning/grinding noise on occasion. Normally, I'd just shut down, boot up, and it would be fixed. Well, yesterday, that didn't work. After being told by the support guy that my free phone support expired 14 days ago (Mac bought in June), he said he'd do what he could to help. I told him about the noise and held the phone up to it (it is coming from the right of the trackpad). He said he had never heard that before and said to take it in to the Apple Store. I've found an Apple Support article, but it doesn't shed a lot of light on the situation.
