Can anyone can tell me?

OS X :: Strange Noises Coming From System / High Pitched Noise Near The Keyboard

Mar 27, 2009

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?

MacBook :: Strange Noises After Installing Updates / Noise Coming From Fan?

Dec 21, 2010

I recently purchased a gently used MacBook. Running 10.5.8. The computer sounded and operating perfectly until I made the following software updates:

MAC OS X Update Combined
Security Update 2010-007
Remote Desktop Client Update
Airport Base Station Update
iLife Support
Java for Mac OS X 10.5 Update 5
Java for Mac OS X 10.5 Update 8
Airport Utility

Now I have an annoying hum noise, that could possibly be the fan.I have run Disk Utility, but the annoying hum noise remains. Does anyone have any suggestions before taking this by an Apple Store.This was intended as a Christmas gift for my wife. Can anyone spare me the embarassment?

MacBook Pro :: System Making Strange Noises / Noise Increase When Notebook Is Moved

Dec 25, 2010

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.

MacBook Pro :: Making Strange Noises In The HDD?

Dec 9, 2009

I bought a MacBook Pro about 10 days ago and it had several dead pixels. That got swapped out for another one which had bubbles of liquid under the glass. I'm on the third now which has a slightly warped case and is now making this clicking noise (0:15) every minute or so.

I don't know what to do - I feel so awkward going in and asking for another swap. Has anyone else got this noise?

PowerPC :: Unable To Start Powerbook / Freezing And Strange Clicking Noises

Oct 5, 2007

So I've got my mothers aluminium 12" Powerbook here because there were some troubles with it, it was freezing, made strange clicking noises on the left side (like 20 times every time she tried to restart) and eventually wouldn't start up anymore. So I guess there must be something wrong with the harddrive .

What is the best strategy to try to save as much data as possible? I have the original OS X 10.3.4 installation disks, I have an external hard drive to write the users data folder to. Do I just slide in the install disk while starting up (I mean I can't slide in the disk while it's off can I?) and will I be able to attach the external drive in order to copy the files?

Sep 10, 2010

Just accidentally rolled my MacBook Pro over a chair (About the height a little over one MacBook Pro's screen) while it was inside it's case.)

I then later found that it had strange DVD drive noises after the drop-There were 2-3 DVD grinding noises longer than the usual grinding noise at the beginning of a startup.

Is my DVD drive now dead?

MacBook Air :: High Pitched Whining Noises Coming From CPU?

Feb 1, 2009

I have a 1.86ghz 128GB SSD Rev B Macbook Air. The first one I had made a high pitch whining noise when the processor was idling or under light load. It was a very very high frequency noise, and you could only really hear it when the room was totally quiet - or unless you put your head near the top left side of the keyboard (where the CPU is located). A bit of googling and it seemed that older Macbook Pros also seemed to have had this exact problem.

I took it to the Apple Store and a Genius there took it back and said he could hear it as well. He offered to go through the repair process but since that would have taken awhile, I got an exchange instead from where I bought it from. Unfortunately, this new MBA also makes the same noise but to a slightly lesser degree (though it's possible that the frequency range isn't as high so it's not as piercing... hard to tell though).

Since this is my second RevB Macbook Air with the problem. I realize most people have lower noise sensitivity than me, so you might not notice it unless you place your ear to the top left of the keyboard. (And just to be clear, this is not a fan noise or a noise from the SSD - which don't make noises anyways. I am 100% sure this high pitched noise is coming from the CPU or somewhere on the logic board.)

PowerPC :: IBook Making Funky Noises / Mechanical Sound Coming From CD-Rom

Feb 28, 2007

but anytime someone pounds on the table and I have my 12' iBook just chilling on it, it makes a resetting noise, a very mechanical sound that makes it seem like it's resetting itself once. I have no idea why, and I just beg people around me to regulate their anger.

However, even when I am picking up my iBook it'll make the noise.Is this a sign of a deteorating cd-rom drive? Or are most iBooks and Apple laptops like this?

PowerPC :: Squeaking Or Scratching Noises / Noise Coming While Processor Works

Nov 2, 2007

I have a PowerBook G4 15" Laptop and it's recently started making a buzzing noise. It drives me crazy! The noise seems to come from the processor and happens whenever I'm scrolling through web pages, hovering over my dock, launching applications or pretty much whenever the computer is doing anything.

I've googled the issue and found it to be quite common, even being some posts on this forum. Here's the best info I've found so far:

"The squeaking is actually the processor going into Nap mode, and has been noticed on a number of G4 and G5 models. To save power when the processor has a little bit of idle time, it essentially turns itself off. What is happening when it's squeaking like this is it is alternating very rapidly between going in and out of Napping as the processor waits for more things to do. I've noticed that it happens most often during an active SSL connection; an https:// connection, Software Update, checking E-mail on a secure server, or any other secure connections can make this squeaking noise. There are many other ways to produce it too, such as scrolling through a web page or some other more graphic-intensive process.

If you want to check and/or get rid of it, you can download the CHUD tools (part of Apple's Developer Tools, and also available separately). The Processor preference pane (formerly called Hardware) will let you disable Napping, after which point the squeaking should go away. The squeaking also goes away if you reduce processor speed by turning Energy Saver processor performance down to Reduced. However, I'd recommend that you leave Napping enabled (to reduce heat output and increase battery life), so leave it in the default state."

I've downloaded the CHUD tools program and turned off Nap mode, I think. But it still makes the noises! I cannot figure out how to reduce processor speed. So frustrating. Anyone have any advice?

OS X V10.7 Lion :: Strange System Files Showing Up Everywhere?

Mar 26, 2012

Roughly two weeks ago I started noticing all kinds of unfamiliar system files showing up in a number of my folders. They are always grayed out and as far as I know have nothing to do with the actual folder. These are just straight forward folders and/or my actual Mac hard drive. Any idea where they may be coming from? I don't know that any of them are actual system files that might be important. The second link, the CODES folder should be the only file in that folder. Here are links to a couple of them. [URL]..

Mac Pro :: Getting Strange Designs And System Freezes On Boot Up

Jun 9, 2012

I was using my mac pro 3.2 octo from 2009 without any troubles. Recently it started giving non stop trouble. I have 2 gb ram from the factory and another 2 from 3rd party. My problem is when I boot my mac I am getting some strange vague designs and it freezes. I tried shifting the boot hard disk from slot 1 to slot 2, booting with either set of ram, changing the graphic card slot etc.

PowerPC :: System Making Weird Noises / Permanent Spinning Beach Ball?

Apr 14, 2007

1.33 Ghz) has started acting up, and while I think I know what the problem is, I'd like some confirmation.The symptoms:

After starting the PB up, it runs for about 5 minutes before we get a permanent spinning beach ball. When the beach ball is up, I hear what sounds like (and is coming from) the hard drive. It sounds like it's spinning either way to fast, or as if something is wrong with it. All the open programs freeze, and we do a forced shut down.Also, the first time this happened, we had a song playing in iTunes. The song would play a 2 second clip, then stop, then start, and continue to stutter.

We've tried turning the computer off, unplugging the battery and the power, but it still does this.I think it's a hard drive problem, and that we need a new hard drive. Does this sound correct?

PowerPC :: System Making Loud Noises / Gray Screen With The Apple Logo At Startup

Jul 12, 2006

I have a Rev A 12 inch Powerbook - 867 mHz, 640 RAM, 40 GB hard drive. The machine's always been reliable and has performed great over the years. I bought it the last week of July, 2003.

Yesterday, the Pbook was shut down, and I press the on button so it would boot up. Almost immediately, the hard drive makes a loud, whirring noise. The computer advances to the gray screen with the Apple logo, but it doesn't get past that point and the noise continues, as if it's a car engine that just won't start...

I'm going to take it to my local Apple Store in the morning, and hopefully the data, including my nearly 22 GB of music, can be saved. Any thoughts on how to get my computer working again? By the way, it's the original hard drive installed. Hopefully this is enough info to generate some ideas, I'm stumped.

Mac Pro :: System Freezes For Few Seconds / Strange Blue Screen With Flashes Appear

Oct 5, 2008

On my 1st Gen Mac Pro, I suddenly get a strange blue screen out of no where. Everything on the screen freezes for a few seconds then the screen flashes blue for another few seconds. After the screen comes back from the blue, everything works perfectly again. Even when listening to music, music pauses for a few seconds and then comes back. This happens a couple times a week and its getting on my nerves. Sometimes it lasts for a long time and requires a hard restart.

I have tried reinstalling Leopard/tried hardware test/upgraded to the 8800GT video card and the 3870/I cleaned the whole inside of the box with compressed air. I even took her into the apple store and had a genius look at it over night. They told me everything is working perfectly. Ofcourse it started doing it again after I got home with it. The apple store suggested that I could always replace the logic board but they want over $1000.00 for that and I dont know if its worth it.

MacBook Pro :: Plink Noise Coming From New 2.2 System

Mar 2, 2008

Just got a new 2.2 MBP delivered to me yesterday. Didn't seem to have any problems at all until about an hour ago. I just began hearing a metallic "plink" noise every few minutes or so. Its not a click or a tick but more like a hollow plink. It comes at random intervals but sounds like it may be coming when the hard drive(?) or something inside the machine spins.

OS X V10.7 Lion :: System Unresponsive After Coming Back From Sleep

Mar 29, 2012

I leave my imac on at night, from screensaver it goes to a black screen but I have selected that the hard drive never goes to sleep. In the morning when I click the mouse or a button on the keyboard it shows me a frozen screensaver screen and the imac is totally unresponsive. Have run disk utility and everything seems totally fine there. It is impossible to use the force quit option so have to resort to switching the whole thing off from the power button.

The software is all up to date and since disk utility shows everything in perfect working order I am puzzled what this is. A corrupt file or app? I am not a heavy user so no games installed - only software installed is the caffeine app, microsoft office for mac which is compatible with my imac, skype and that's all. Lots of free space on the hard drive too. I am not an expert on macs so I don't know how to look in case something in specific causes this that I can uninstall.

MacBook Pro :: System Making Loud Noises / Loud Sound On Start Up ?

Aug 23, 2009

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.

Mac Pro :: Buying A Mac Pro On Ebay Is A Bad Idea?

May 28, 2009

Does anyone think the Mac Pro will get any changes at WWDC?

I am in the market for a new Mac Pro. I have settled that I do not need 8-core power. I found a good deal on eBay and not sure if its a good idea to buy one off of eBay when WWDC is less than 2 weeks away. Anyone feel there will be a speed bump, case redesign, snow leopard?

If snow leopard came out, does anyone know if Apple includes free upgrade for new systems from a certain date?

Any advice on whether buying a Mac Pro on ebay is a bad idea? Does Apple take PayPal receipt for eBay purchase as a valid proof of purchase? I've never had to provide a receipt for my Macbook Pro even though I did buy it at a true reseller.

OS X :: Mac Has Been Quitting Unexpectedly, And Have No Idea?

MacBook :: System Making Odd Noises / Noise Got Louder And Louder

I searched some forums and someone said that it means your hard drive is dying. What do you think it is? should I go into Apple and have them look at it?

Mac Pro :: Pitched Noise Coming From System / Connected To External Audio Interface?

Jan 6, 2011

just got happy about the fix for the audio / performance problem of the 09 mac pro's. Why should it be different, the next problem knocks at my door, hallelujah...

When I connect my external audio interface (apogee ensemble) to my mac pro, the mac begins to whistle...

As soon as I turn off my interface again, the whistle is away immediately . The sound is definitively coming from my mac pro and I couldn't locate the problem to a fan. I think it's maybe the firewire controller chip? When I connect my external lacie HD I have no problems at all. I have tried it on both ports on the back side with no success.

The whistle is not constantly on the same noise level. Sometimes it's away for a few seconds, it's high pitched and really annoying though. It does not matter if I playback audio or not. Nothing worked though. I experienced the whistle in the past few months sometimes but it was mostly just for a few minutes or so. But in the past few days it was constantly and it never really stopped. This drives me crazy when I have no audio playing and my room is silent !!

I have no other firewire cable (400 to 800) around to test it. Could this be the culprit also?

MacBook Pro :: Trying To Get An Idea Of Font Size On A Hi-res 15" MBP?

Apr 30, 2010

If you have a 1440 x 900 15" MBP and you reduce the screen to 80% in Firefox or Safari I think it's very close to the font size you'll find standard on the hi-res screens.

Then to get an idea whether or not you're pleased with the font size try using your notebook at this setting for a few days.

My initial experience with the small fonts on the hi-res screens in the area's were the fonts couldn't easily be resized I didn't like it at all the first few hours I typed on it -then- I started to like it, the fonts are smaller but sharp and crisp I was getting sold on the idea of the hi-res screens. Finally, after a few days using the laptop for long periods of time I found my eyes where "much" more strained, not because I couldn't enlarge the fonts on the page I was typing on it was everything else; menu text etc ... glancing and refocusing to view the smaller fonts became tiring on the eyes, making them feel dry/heavy.

I then went back to the 1440 x 900 screen and the eye strain disappeared. I wanted to buy and like the hi-res screen, but not doable for me.

This post was meant to help anyone who's trying to decide what to do but isn't near an Apple Store to take a look for themselves.

The above font size should also be similar.

*** Keeping in mind it will look more sharp and crisp on the hi-res display.
