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.
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 a macbook ALU. When I stay in bootcamp with windows if I put the brightness between 30 80%
I listen a high pitch with nvidia drivers if I uninstall the drivers I don't have this problem.
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.Â
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.Â
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.Â

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?

View 4 Replies View RelatedI 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.
View 2 Replies View RelatedJust got my new i7 in the mail today after waiting for the refresh for 5 months and it has that stupid high pitched noise that you get when you adjust the brightness. I returned four of these things at the beginning of the year (2 HD failures, 1 power source failure, 1 DOA), one that had the hd failure also had this same high pitched noise.
I love these computers (minus the complete lack of quality control), so I don't want to switch back to PC, but I am at my wits end here. Apple already gave me $150 off this computer for me trouble, but I just don't know if its worth the hassle anymore. I am returning it for sure, but would you ask for more compensation, maybe a ram upgrade or something? I don't like to be the guy who asks for free crap, but the way I see it, they can give me another hundred $, or I can go back to pc and they lose a customer for life.
I have this high pitch sound that started intermittent this morning .
Now it's getting more frequent and last longer.
It just stopped when I moved the power saver setting of the video from never to an hour.
I'm not sure where it's coming from yet.
i was bored and decided to put my ear up to the area right of my air's trackpad, my ear was actually pressed up against the case. oddly enough, i am able to hear a somewhat high pitch beeping sound every 5 seconds. anyone else care to do the same and report back?
View 2 Replies View RelatedI just purchased a mac pro about 4 months ago and I love it, I have never had a problem with it until today, I went to install a new program on it and it did not even read it, it made a hi pitched sound for a short time then stopped, waited about 10 seconds did the same thing. After a couple times of doing this it would eject the disc, so I figured I would try another disc, I have tried many different discs such as games, cds, programs and nothing has worked.
View 7 Replies View RelatedWhenever 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.
View 2 Replies View RelatedWhen I turn it on it runs fine for sometimes about a minute (sometimes less) before it just turns itself off! After it turns itself off I'll hit the power button and it emits a high pitch squeal from the machine whilst holding the button. If I then remove the battery from the Machine depending on how long I leave the battery out and put it back in, it will then power up for a short amount of time. Sometimes I can get it to the desktop and open System Profiler for example, other times it gets as far as the Apple grey screen. I've ordered a power adaptor as I didn't get one with the machine but as far as the battery indicator goes, it's on 96% and all four green lights are on the battery indicator on the base. Has anyone heard of any problems like this before?I believe it's running a 500mhz processor and has 512mb of Ram.
View 3 Replies View Relatedrite as some will already know i have took back my 27" iMac a total of 6 times and now i am on my 7th (4th one had screen issues), after actually accepting the "belly rumbling" "popping" noise and just getting on with the i5 experience, i thought i would actually contact Seagate direct on the actual matter for the rest of people on here who have doubt about there seagate hard drives.So i ring the operator i told him the whole story his first reply was sorry we dont support apple hardware! my response was "respected but the hard drive used is a seagate product"! he then replied saying sorry sir i misunderstood and quickly responded how can i help. I then repeated the problem and he asked for the HDD serial number, i was then very specific on the the noises we are all hearing and he made me repeat what i said a good 3 times so he had a very good understanding (in other words he did take this all seriously) he then said he was going to talk to the relevant person and put me on hold....10 minutes later he's back on the phone and he again asked me a final time! (ffs) to explain the noise he then quickly said in response the hard drive is supposed to make that noise. he named it the barracuda in seagates terms.

View 4 Replies View RelatedI'd really love to get an i7 machine, but I simply do not have the space for such a big screen on my desk. Also, I kind of prefer having a 1920 by 1080 resolution display so as to view HD material at its native resolution without uprezzing. Drives me nuts, because I'd gladly spend $300 more for a 21.5 inch with an i5 or i7, but since I'm stuck looking at a C2D machine, I'd like to know how people who've had this CPU have found it to be for things like Final Cut and Aperture. Has anyone got any comments they can share?

If I replaced the fan would this solve the problem or could it be the power supply?
Can anyone provide me with a some extremely high quality wallpapers for my 27" imac? This screen is so huge, almost anything I use is somewhat blurry.
View 10 Replies View RelatedI bought one of the new-gen iMacs last month--my first Mac! My computer will often start making a low-droning noise, and it sounds like a fan. I have iStat, and usually during this time it will say that my Optical Drive and CPU Fan are both running at around 4000rpm. This happens when there is very little CPU usage too. It's happening right now, and I only have firefox running.
View 11 Replies View RelatedBeen using my imac lately and I've noticed a drop in wi-fi signal. I checked iStat and it said that the airport card's temp was 62?CIs the high temperature linked to the loss in signal?
View 1 Replies View RelatedI just recently bought an imac computer and my two friends who know a lot about apple computers thought that the fans and temperature might be a little high. The cpu fan at idle runs at just under 1200 rpm's, the harddrive fan runs at 1100 rpm's and the optical drive fan runs at 1000 rpm's. The temperature itself 40-44C. The other imac that they know of is a year old, so we weren't sure if there were newer upgrades that might be making the difference between our speeds and temperature compared to that one.

Are there any iMacs that have High Definition screens? I've seen people selling High Defintion iMacs on eBay but is it true? Are the external Apple monitors High Definition, too?
View 18 Replies View RelatedI'm seriously considering ordering one of the brand new 27" iMac's, with the 2.8 GHz i7 Processor and 8GB (4x2GB) of RAM. The only thing I'm having trouble deciding about is getting either the standard 1TB Hard Drive or the 2TB Hard Drive for a little over $200. Since the Hard Drive can't exactly be replaced easily, I'm wondering if it would be better to invest in the 2TB upgrade.
View 17 Replies View RelatedI have a 24" aluminum iMac G5. I have never had a problem with sound before, and feel like this problem is isolated to a certain DVD but the DVD works on EVERY other player I own. Everything pretty much plays DVDs, so that's many!
So here's my problem: There's parts of this movie that have very high pitched sounds, like electronic sounds that are just sound effects in the movie. Whenever I get to those parts in this movie (maybe even other movies for all I know, I don't play many) and the sound goes quiet, like the speakers can't handle that high pitched sound.
I feel there must be something I can do about it, right? I just use the regular default DVD player application that pops up when I put a DVD in. I tried playing with that equalizer but nothing changed.
If you're having this problem, try adjusting your brightness. I was experiencing this issue today, and depending on where my brightness slider was... it got worse, better, to non-existant.
