Make sure the air vents are clear.

My iMac 27" is making noises like grumbling

Well there are air vents on the bottom or the back or both so you would blow compressed air into those areas or when they are changing the drive have the service center do it as it is easier and better to do it when the system is opened up.

MacBook optical drive has started making noises at wake and restart

This MacBook is about 5 months old and the optical drive has just started making noises at wake from sleep, or at restart. There is no disc loaded in the drive, but the noise is as though a disc has been inserted in the drive and it is attempting to read it. This goes on for about 5 to 10 seconds, then stops.
The optical drive seems to work fine, reads CDs and DVDs no problem. This isn't a glaring issue, I'm just trying to determine if it is the precursor to a mechanical problem, or is possibly some sort of software glitch. Thanks for help if this rings a bell with anyone.

I posted this to a different thread earlier today. I will add that most of the experience I've had with this issue is in Tiger or Leopard. I don't think I've seen it yet with Snow Leopard. My instincts tell me it is more of a hardware issue than a software/OS issue. (Just my $0.02.)
I have seen this many times. (I support 100+ Mac Laptops, most are 13" MacBooks.)
Just to clarify, MacBook optical drives do normally make some quiet noises when waking from sleep.
When there is a CD or DVD in the drive, there are some soft sounds, and then you hear the disc spin up. When there is not a disc in the drive you hear a different sound. I assume it is relating to checking for a disc in the drive. To me, it sounds exactly the same as the quiet sounds you hear right before the "Good Chime" when you power up.
BUT, sometimes MacBooks make a much louder noise, that is similar the sound you hear when you insert or eject a CD or DVD, only sort of "doubled". Usually you hear it when waking from sleep, but I have also experienced it happen intermittently when the MacBook is turned on, under normal use, or not being used (but not sleeping or waking from sleep).
In the past, I have sometime cured it with a reset of the SMC and PRAM. This has not always worked. I have also seen it disappear after inserting a disc into the drive. Most of the time, the sound has returned some time later. I have called Apple on this issue several times, and sent the MacBook in for repair. My memory is that they have replaced the optical drive under AppleCare.
I will add that I have recently seen this Knowledge Base Article (below), with instructions for "resetting" the optical drive on a MacBook Pro, but it did work for me on a MacBook 13". Insert a disc halfway, take it back out, then put it in all the way.

Past experience tells me not to be surprised if the noise resurfaces. My advice is call Apple if you have AppleCare, or if the MacBook is under one year old.
Good Luck.

Your iMac should be almost silent.
Make an appointment with your Authorized Apple Service Provider.

IMac from 2009. Suddenly making noise like a loud fan.

My IMac from 2009 is suddenly making noise like a very loud fan, or a little like a vacuum cleaner. The sound seems to becoming from the IMac, not my speakers. Could this be from any of the wires or connections plugged into it? Restarting the computer did not stop this. I think this happened once before a long time ago. Anything I can do?

Before I saw Mike Sombrio's post:
I restarted the IMac without unplugging the power cord, but the noise was still there when the IMac came back on. Then I repeated this about 10 minutes later, (restarting the computer without unplugging the power cord). This time the noise was no longer there. I don't know what's going on. I hope this problem does not return. Any explanations? Is this a sign that my IMac is having serious problems? Any advice?

IBook suddenly started making noise

Hello!
My iBook G3 suddenly started making noise. When you dont do anything on it, its quiet, but when you open apps, write stuff to disk, its loud. How can I avoid this?

It sounds like you may be having some hard drive issues.
Try booting into Safe Mode. This will take quite awhile longer than a normal startup because it does a file check and repair of the hard disk.
You will see your normal desktop. Once completely started up in Safe Mode, restart normally, and go to Applications > Utilities > Disk Utility. Click on the top hard drive icon in the left sidebar and note the S.M.A.R.T. status at the bottom right of the pane. What does it say? If it says "Verified," you should be in good shape, as far as the hard drive is concerned, at least.
Select the named boot volume in the left sidebar, ("Macintosh HD" unless you've renamed it). What is the hard drive capacity and how much space remains available on it? Repair permissions on it.
See if a little hard drive maintenance helps things out.

My imac just started taking a long time to turn on. First I have a grat screen, than a gray world globe , a blue screen and finally my desktop. A total of 4 minutes. What is wrong and what do I do?

My IMac , just started, taking a long time to get to the desktop. First I have a gray screen, than a gray screen with a gray globe, a blue screen and finally my desktop. Takes about 4 minutes. What is wrong and what do I do?

Once the desktop is up and the iMac ready to use, open Systeem Preferences (Apple menu) and click the Startup Disk item. In the new screen, make sure that OS X on your hard drive is selected in the top row - click it once to make sure. Then test.

IMac external speakers making noise

I am not sure if this is the correct place for this question...
but my speakers I have connected to my iMac make an annoying staticky noise all the time. It does this no matter what volume my iMac is set at, but it will go away if I turn the volume down on my speakers. When I plug my iBook or iPod in, the sound is not there. I have replaced cords and tried different inputs on the tuner, but the noise is still there.
Is there some kind of option for the iMac sound output to fix this?

Hi Don,
Griffin made the iFire a few years ago that does just that...connect the Pro Speakers to any computer. Google it and I'm sure you can find one.

My iphone4 just starting making peoples EYES WHITE when taking pictures. Why

My Iphone4 just started taking photos of people with WHITE EYES. Why is this happening and how can I get rid of the white eyes on the photos. This has totally ruined my photos from a wedding shower. I have never had this problem before and always use the Iphone camera for hundreds of people photos. Please help becuase I do not want to trust my Iphone4 camera for any people photos. thanks

You can get *some* relief by going to Settings > General > Accessibility menu (look for the "Reduce Motion" option). This does not turn off all the effects, but it might help.

Just upgraded to IOS6 on the ipad and found there is no Youtube, chance of getting that back.

Just upgraded to IOS6 on the ipad and found there is no Youtube now, any chance of getting that back?

You are only as young as you feel......
This is an example of how you can select the exact content that you want to sync to your device. You do not have to sync the entire iTunes library. You can pick and choose the music, apps, books and so on that you want to sync. This is using music as an example.
Connect the iPad to the PC and launch iTunes.
Click on the iPad name on the left side under devices.
Click on the Music Tab on the right.
Click on only the albums or playlists that you want to sync.
Click on the Sync Music Heading.
Click on Apply in the lower right corner of iTunes
You can do this with apps, books, movies .... Whatever .... You have the freedom to sync whatever you want.

My MacBook (08) just started making a noise that sounds like a fan...

It's like the computer is working really hard to function. Programs are also running slowly. I checked the Auto Update, and everything is up-to-date. Is it on its last legs?

iStat Pro does not quite work "as always" with newer systems.
For one thing, it may report inaccurate temperatures (& possibly fan speeds), depending on the Mac model it is running on. (For instance, on my system, it tells me the ambient temperature is around 54° F in a room that is actually about 77°.)
The problem is basically that iStat Pro gets temperature & fan speed info by querying the SMC subsystem. Apple has apparently changed the query/response protocols or the SMC hardware itself, so this no longer works as the utility expects.
And Banjo is not as "safe" and digs too deep with core kexts.
Banjo is the new name for the same company that developed iStat Pro & the original & newer iStat Menus programs. My guess is that the latest version of iStat Menus is just as safe to use as the earlier ones.
However, I won't use it for the same reason I won't use MenuMeters: both rely on MenuCracker, a hack to work around Apple's restriction of menu extras to ones Apple develops & distributes as part of the OS itself. Developers are specifically told to use 'Status Items' for their menu bar add-ons, which offer some but not all of the same functionality as menu extras, & do not risk destabilizing the OS or compromising its security.

My iMac recently started making random beeping noises. They are all different pitches and lengths. Nothing like a notification. Also does it with the sound muted. I've deleted Skype (several people recommended that) and restarted & shutdown. Please help!

This has been going on for a few months and seems to be getting worse. At times it will be frequent, other times only a few random beeps an hour. Seems to be worse when something is loading or "thinking". I have a video of the beeping sounds I will upload when I get home as it won't let me do it here at work. Any suggestions are greatly appreciated, it is driving me crazy! I'm also worried it will crash on me.

Beeps on startup:
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images.
5 beeps = processor is not usable

HT1320 My 3rd generation iPod won't turn on and just started making a were beepin noise? What does this mean and how can I fix it?

The back light turns on and I can hear the click wheel but no apple sign comes up on the screen. Any guidance would be much appreciated ;)

It's possible that your iPod is working to some extent (since the backlight is on and the click wheel makes a sound when used), but the LCD screen is not working. First, try doing a Reset (which restarts the iPod)
http://support.apple.com/kb/ht1320
Even if it is still not working, does anything change after doing the Reset?
If that does not help, when you connect it to your computer's USB and run iTunes, does it appear in the sidebar under DEVICES? If it does, select it in iTunes and try doing a Restore. The Restore button is on the iPod's Summary screen in iTunes. This will erase the iPod, reinstall its software, and set it to default settings.
If the iPod does not appear in iTunes when connected, or if doing a Restore does not solve the problem, the cause is likely to be hardware-related.

IMac just stops, turns off like the plug was pulled.

My iMac is a 17in G5, running 10.3.9, with 2MB of aftermarket RAM installed (by me over a year ago) and lately, it just turns off. It doesn't freeze, and it doesn't warn me. It just turns off like the plug was pulled. When I try to start it back up, no problem. Boots back up like normal....though if you look closely, a little "?" appears ever so quickly in the folder in the middle of the screen before I see the Mac happy face.
I bought it new new 3.5 years ago (no more apple care) and it has lived a pretty easy life, until my little one started walking and climbing. Since then, my little guy has turned the power strip off probably 20 or 30 times, thus killing power to the computer without shutting it down properly. Also, I am encountering a seeminly unrelated problem with my disc drive. It no longer runs or burns DVDs. CDs, no problem. DVDs, no comprendo.
Things I have tried.
I bought an external DVD drive. One problem fixed. For the random shut donw problem, the only thing I could think to do was to unplug everything, wait 15 minutes, and then plug everything back in. That made no difference.
Anybody have a suggestion? Is my computer nearing the end of its life? So soon? Right after apple care expired? Oh no!
thanks for any help,
Adam
