Noisy imac, tried SMC
My Imac has recently started making a loud fan noise, its only 15 months old and i haven't battered it.
read a few articles and tried both SMC and PRAM but its not helped still exactly the same ??
guessing its a back to the shop job, but just wanted to double check first.
/hansen,
If it's really noisy, you may well have an iMac that has a problem. Some do and get them fixed. Some don't and still try to get them fixed. I'm not sure that there's room inside for any sound deadening material, so that they're as quiet as they are is pretty cool.
I must say that all of my iMacs are "dead silent" - when they're shut down or asleep:))
When some use the dead silent description, I think they're trying to make a point by overemphasizing just a little. You shouldn't take them seriously, as some are simply making a comparison to their previous computer experiences. Some may not hear as well as others, while some may have overly sensitive hearing. Some claim to hear a hum, or a buzz, or a whirr, or a chirp - say it's one fan, or the fans, or the hard drive, or it's electrical in nature. It's just not possible for us to be able to relate exactly what we hear or don't hear if we don't measure to quantify the sound.
There are fixes - SMC resets, PRAM reset, adding RAM, software updates. There's one thing I know for sure - triple the size, fill it with sound deadening material, and raise the price, and the iMac will be dead silent all right. Best of luck.

My MacBook Pro 2009 won't turn on. It suddenly won't charge and when it did, I shut it down and now it won't turn back on. Charging shows green and the green little dots are showing on the side. I tried smc reset, command+p+r. Any other suggestions before i take it to apple service center?
A four year battery could be dead. I'd contact an Apple Service Center.

Here's what I've tried;
SMC reset
Pram reset
Looked at activity monitor - mostly seems OK aside from a kernel task taking up memory (approx 460MB) but CPU is around 96% idle.
Fan seems to be running constantly - heats up noticeably when I close the MBP
Despite a re-install of Mavericks, MBP is running frustratingly slow. Just typing is enough to bring on the beach ball.
Have backed up everything, reinstalled from a clone, checked through Apple Hardware test and carried out a Verify Disk Permission - nothing was reported, erased the drive and set up again - problem still stands.
Memory is running at 3.43 GB without anything really running bar Safari.
A little loath to install SMC fan control without knowing what's wrong.
Checked software updates.
Can anyone tell me what the matter is? Does this have a fix?
Have been reading up various posts but to no avail so have resorted to posting myself.
Does this sound familiar to anyone?
Many, many thanks
Roque1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem. But with the aid of the test results, the solution may take a few minutes, instead of hours or days.
2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. Backup is always a must, and when you're having any kind of trouble with the computer, you may be at higher than usual risk of losing data, whether you follow these instructions or not.
There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
Here's a summary of what you need to do, if you choose to proceed:
☞ Copy a line of text in this window to the Clipboard.
☞ Paste into the window of another application.
☞ Wait for the test to run. It usually takes a few minutes.
☞ Paste the results, which will have been copied automatically, back into a reply on this page.
The sequence is: copy, paste, wait, paste again. You don't need to copy a second time. Details follow.
4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode, under the conditions in which the problem is reproduced. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it. If you try to select the line by dragging across the part you can see, you won't get all of it.
Triple-click anywhere in the line of text below on this page to select it:

Copy the selected text to the Clipboard by pressing the key combination command-C.
7. Launch the built-in Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Click anywhere in the Terminal window and paste by pressing command-V. The text you pasted should vanish immediately. If it doesn't, press the return key.
8. If you see an error message in the Terminal window such as "syntax error," enter
exec bash
and press return. Then paste the script again.
9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
[Process completed]
to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
At the top of the results, there will be a line that begins with "Model Identifier." If you don't see that, but instead see a mass of gibberish, you didn't wait for the "Process completed" message to appear in the Terminal window. Please wait for it and try again.
If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

If you downloaded it then presumably it downloaded as a compressed file, likely a .dmg file. If so double click it to mount the dmg as a folder on your desktop. Open the folder and you will see the files. Drag the folder to a location of your choice. e.g., Applications). Then you should be able to execute the application in that folder.
Just to confirm, when you said you "put the software in the iMac", what was the name of the "software" file you copied? -
Hi there.
I'm thinking of getting an iSight but I have a very noisy iMac G5. The fans are loud and it makes a whining noise too. (Long story but Apple say there's nothing wrong with it.)
How good is the iSight at filtering out background noise like this?
iMac G5 Rev. A Mac OS X (10.4.4) 1.8GHz 1GB RAM; iPod nanoSorry, I should have made myself clearer.
What I'm wondering is, will the noise of my computer be picked up by the iSight? Will the people on the other end that I'm chatting to be able to hear me above the din?!

Hi there !
I am enjoying my new iMac 20" since the last two months. Recently (one week ago), it began to become a little bit noisy.
Nothing horrible, but you can notice a little noise (sounds like a fan) I only used to hear when the CPU load was high for a long time (Google Earth, movie editing...). But now, the noise is continuous, and starts when the computer powers on. I checked the activity, and the CPU is still at 0.00%. This is the kind of noise you cannot hear if, for instance, someone is talking near you, but you will notice it if you are in a quiet room.
It is not the standard noise of my iMac, which used to be an absolutely noiseless computer.
I tried a SMC reset (unplug the cables...), but it didn't solved the problem. I noticed on other forum that some guys had exactly the same issue. I would really appreciate some help, because I am getting worried something is going wrong...--Nicolo--,
The do it yourself repairs that were allowed on the first generation iMac G5 are not allowed on the iMac Intel, and would not likely be useful if they were, since the machines are so different. Thanks to the Intel processor, iMac Intels don't generate anywhere near the heat as did the G5s.
Rather than planning anything major to try and achieve a fix, it seems to me that since it's such a minor noise, your approach should be to take minor steps such as those you already did (SMC reset, Hardware Test, and disk repair from booted install disc). I'm sure at some point you also must have repaired permissions from the internal version of Disk Utility, as well.
Additional small steps to try might be:

2. return to the original RAM followed by a second PRAM reset

Wonderful .... but noisy iMac .... and decommissioning the HDD
I've just bought my first Mac (27" iMac i7 3.4GHz 1 Tb Western Digital HDD, 256 Gb SSD, 8 Gb RAM, 2 Gb Video) after a PC lifetime and it's wonderful ..... but noisy .... surprisingly noisy for such an expensive supposedly high-end computer.
The noise is coming from the HDD which I viewed as almost a freebie when speccing the BTO menu as the extra over cost versus a SSD only machine was relatively marginal. Temps and fan speed are all normal as reported by iStat so nothing is malfunctioning per se that would warrant a return under Applecare.
So whilst the noise is irksome and dents confidence and brand image somewhat, I'm pragmatic rather than nuerotic about it and I'm thinking that I can add a Thunderbolt external HDD when the prices drop a little and switch off the internal HDD.
Is anyone please able to confirm that it is possible to electronically rather than physically decommission the HDD so that it will sit silently within the iMac shell, never being used once I have an external TB HDD up and running.The correct process for resetting the SMC and PRAM is:
SMC RESET
Shut down the computer.
Unplug the computer's power cord and all peripherals.
Press and hold the power button for 5 seconds.
Release the power button.
Attach the computers power cable.
Press the power button to turn on the computer.
PRAM RESET
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys. -
Noisy imac G5 and CPU settings
Ref- imac G5 2ghz, 10.5.6
Hi All,
I just wanted to put forward the symptons of my imac G5. Due to noise I run the imac at the reduced CPU setting to avoid the noisy fans but lately it seems to have started getting louder and its a little bit annoying. I would love to run it at the highest CPU setting but the fans go mental but it does improve performance, I would like to think that I could be getting the full 2ghz power from the machine.
I have tried cleaning the machine inside and out and also reset the PRAM but still no joy. I wonder if anybody has any suggestions on this, I appreciate that this topic has come up in the past.
ThanksHave you made sure that the fans are dust free and securely screwed down?

Very noisy iMac, fans running at full speed even when performing smal tasks
I have a 2009 21 iMac, recently the computer became very noisy with the fans running at full speed all the time even when checking the email or just using Safari. I don't do anything crazy like 3d renderings so I don't know why the fans wont stop. I recently cleaned it but this didn't seem to solve the problem.
Anyone knows what's the problem and how can I fix it?

IMac tries to start in safe mode but fails.
I have a Mid 2010 iMac running Maverick. I added 16gb of ram to the 4 existing which I have done on many Macs. It started up but after a minute or two it forced restarted on its own. I then tried it a few more times and continued to crash then restart. I started it in safe mode. It nearly loaded completely the safe start then shut down. Any time I now try to start it, it does the same thing, starts in safe mode then fails. I have taken the 16 extra gas of ram out and it still fails to load. Any advice would be greatly appreciated!
Have you tried repairing the disk? I know it seems simple but sometimes this can be the problem.
Hold down Command+R when starting the computer, select repair disk from the menu.
This won't delete any data and may not work but it's worth a try. -
On startup, imac tries to connect to a network server that doesn't exist.
Since I migrated my old iMac to the new one, it has been trying to connect to a non-existent "Server at an IP ADDRESS". Actually, it is trying to find a long defunct network media drive.
This glitch also hangs up the Clean my Mac software.
How do I tell the iMac to NOT try to locate this hardware?
CheersPlease take each of the following steps that you haven't already tried. Back up all data before making any changes.
Step 1
If you get the warning as soon as you log in, it's probably caused by one of your login items or a system modification that loads at startup or login. Ask if you need help identifying it. A common offender is "Adobe Synchronizer," which is a component of some Adobe products.
Step 2
If there's an icon representing the server in the sidebar of a Finder window, hold down the command key and drag it out.
Step 3
In the Finder, press the key combination command-K or select
Go ▹ Go to Server...
from the menu bar. In the upper right corner of the window that opens is a Recent Servers popup menu represented by a clock icon. From that menu, select
Clear Recent Servers…
and confirm. Test.
Step 4
Triple-click the line below to select it, then copy the text to the Clipboard (command-C):
~/Library/PDF Services
In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return. A folder may open. If it does, move the contents to the Desktop, or to a new folder on the Desktop. Log out and log back in. Test. If there's no change, put the items you moved back where they were and continue.
Step 5
Open the folder
~/Library/Preferences
as in Step 3 and move the file named "loginwindow.plist" items in that folder to the Trash, if it exists (it may not.)
Log out and back in again, and test.
Step 6
Other possible causes are references in the iPhoto, iTunes, or iMovie library pointing to the server, and bookmarks in the Preview application.
Try rebuilding the iPhoto library. -
IMac trying to connect to another iMac
my iMac is trying to connect to my other iMac on my network whenever I login to this imac
how do I turn this off?
Thanks for any help.There are many possible causes for this issue, and it may be very hard to resolve without wiping your account clean of everything except documents as a last resort. Please take each of the following steps that you haven't already tried. Back up all data before making any changes.
If you get the alert in the login screen before you log in, stop here and ask for instructions.
Step 1
If you get the alert as soon as you log in, it's probably caused by one of your login items or by software that otherwise loads at startup or login. Ask if you need help identifying it. Known offenders are "1Password" and "Adobe Resource Synchronizer."
Step 2
If there's an icon representing the server in the sidebar of a Finder window, hold down the command key and drag it out.
Step 3
In the Finder, press the key combination command-K or select
Go ▹ Go to Server...
from the menu bar. In the upper right corner of the window that opens is a Recent Servers popup menu represented by a clock icon. From that menu, select
Clear Recent Servers…
and confirm. Test.
Step 4
Open the Printers & Scanners pane in System Preferences and delete any network devices you no longer use.
Step 5
Triple-click anywhere in the line below on this page to select it, then copy the text to the Clipboard by pressing command-C:
~/Library/PDF Services
In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return. A folder may open. If it does, move the contents to the Desktop, or to a new folder on the Desktop. Log out and log back in. Test. If there's no change, put the items you moved back where they were and continue.
Step 6
Open the folder
~/Library/Preferences
as in Step 5 and move the file named "loginwindow.plist" items in that folder to the Trash, if it exists (it may not.)
Log out and back in again, and test.
Step 7
Other possible causes are references in the iPhoto, iTunes, or iMovie library pointing to the server, and bookmarks in the Preview application.
Try rebuilding the iPhoto library.
Step 8
Resources such as images or sounds stored on the server may have been added to various applications. Examples would be pictures added to Contacts and custom sounds added to Mail. The range of possibilites here is practically infinite, so I can't be more specific. You might get a hint by launching the Console application and looking for error messages that appear at the same time as the alerts.
Step 9
Disconnect all wired peripherals except those needed to start up. Start up in safe mode. Test. After testing, restart as usual (not in safe mode) and verify that you still have the problem.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Step 10
Triple-click the line below to select it:
/System/Library/CoreServices/Directory Utility.app
Rght-click or control-click the highlighted text and select
Services ▹ Open
from the contextual menu.* The application Directory Utility will open.
In the Directory Utility window, select the Directory Editor tool in the toolbar. Select Mounts from the Viewing menu in the toolbar, and/Local/Default from the node menu, if not already selected. On the right is a list of names and values. By default, the list is empty. If it's not empty, post a screenshot of the window and stop here.
*If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). Open a TextEdit window and paste into it (command-V). Select the line you just pasted and continue as above.
Step 11
Open the following file as you did in the last step:
/etc/auto_master
It will open in a TextEdit window. The contents should be exactly this:
# Automounter master map
+auto_master # Use directory service
/net -hosts -nobrowse,hidefromfinder,nosuid
/home auto_home -nobrowse,hidefromfinder
/Network/Servers -fstab
/- -static
If there are any other lines in the window, post them. Otherwise, close the window. -
My iMac tries to connect to old network startup
Greetings,
When I start up, I receive a message that my computer is trying to connect to the my old iMac, the one that I used with Migration Assistant to transfer files and such. That computer is no longer around, but the new one always searches for it.
I have looked in Startup items, Airport preferences, recent servers in the Connect to Server part of the Finder, and found that there is an icon for "Network Startup" with a ? that I assume is the culprit. However, there is no obvious way to delete or cancel this.
I checked the following discussion threads for answers:
https://discussions.apple.com/message/13272616#13272616
https://discussions.apple.com/message/5317530#5317530
There were many useful suggestions, but so far no luck. There might be more out there, but I have been looking for a while now.
Any help would be much appreciated.
Thanks
KenLook in System Preferences > Accounts > Login Options > See if there is a Network Account Server defined. If so, remove.
Sounds like it's looking for a remote boot option.

Cooling fan on OS X 10.7.5 runs at high all the time. Have tried SMC reset, putting it to sleep
Cooling fan on Mac desktop OS X 10.7.5 will not turn off. have tried resetting SMC, putting to sleep and force quit programs. Started after replacement of hard drive and LCD cable. Please help! Thanks!
Take it back to whom replaced it.
If you did it, you may need to take it in for service. You have to be very careful how you put the pieces back together and neither put on too much cooling gel which would make it an insulator, and not too little.
Maybe you are looking for
