IMac 24 inch wakes up without touching it...

Hi everybody!
At least 2 times in the last two months, my iMac 24 inch has woken up by itself. I put him to sleep (NOT shut down) in the evening, and the next morning it is awake. I have no devices connected, no schedule energy saver start-up or other start-up times installed, no 'starting up after power down' or such things. I have nothing activated that alows outside acces to my computer at night. I don't have TV or anything else. Everything is standard on my iMac. I shut down Safari and Mail before i put him to sleep.
My Apple dealer says that iMacs regulary automatically deframentate, if necessary even at night. But shouldn't it then automatically go back to sleep again?
Does anyone else have an iMac that sometimes wakes up by itself?
Thanks!

If the CPU is awake, regardless of the screensaver being active or the screen being asleep, the launchd timer will run and the scripts will run at the right time, unless the Mac has been restarted, which resets the timer.
If the Mac is off the timer does not run and is reset when the Mac is restarted.
If the Mac is asleep the timer does not run, but begins where it left off when the Mac is awakened and will run the scripts, offset by how long the Mac was asleep, as long as the Mac is not restarted or put to sleep before they are run.
Anacron does not run the scripts when the Mac is asleep or off, it checks to see if the scripts were run at the proper time whenever the Mac is restarted or awakened and every hour. If they were not run on time, Anacron runs the appropriate script.

My iMac (10.6.8) goes to sleep and will not wake up without a hard reboot.

My iMac (10.6.8) goes to sleep after 2 or 3 hours (even if im working at the time) and will not wake up without a hard reboot.
Any suggestions would be very much appreciated.

What all USB or Firewire devices do you have connected?
Safe Boot , (holding Shift key down at bootup), use Disk Utility from there to Repair Permissions, test if sleep/wake works OK in Safe Mode.
Reboot & test.
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.

Can't wake up my iMac 27-inch...

Hey Everyone,
I hope there's someone out there who may be able to help.
I've seen reports of similar problems on other threads.
I've recently got my iMac back from repairs (so glad I got extended cover) the display has been completely replaced, due to two major faults.
1. if the Mac had been off all night, it would power up fine but the screen would just stay black and I'd have to a force shutdown, this black screen problem would also occur if the Mac had been asleep for a while - which would also require a force shutdown.
2. the display had 'what looked like' dirty/dusty marks all along the top of the screen.
I was told that having the screen replaced 'should' hopefully solve the problem.
I brought it home last Friday and booted up with no fuss, however, when it came to be powered a couple of days later, the same problem has begun to happen.
I have replaced the 4x 2GB sticks of RAM with 4x 4GB, but having used Macs for many years, I know these problems are not really characteristic of RAM failure.
I've also got two mains powered USB devices attached, a WD 1TB HD and an LG External SuperDrive, the HD has never caused me any problems, but everything changed after I got the SuperDrive.
As the SuperDrive was plugged in when I got the iMac back, I decided to unplug it and see if it made any difference.
If anyone can shed some light on this problem I'd be really grateful, I'm booked in for another Genius Bar session a week today, but I'm not sure they're gonna be able to help me. plus I'm a little peeved that I'm going to have to buy another external HD to back up my machine.

Is your iMac plugged into the network via ethernet (not on WiFi)? "Wake for Network Access" does not work via wifi. I messed with all kinds of different ways of waking and accessing computers on my home network. I ended up going with Mark Muir's script which can be found here:
http://www.macosxhints.com/article.php?story=20090626025416657
Further info...
I made an Automator application that runs his script to wake the computer I want. I then have Automator do the following to access the computer:
Get the following text: afp://192.168.1.2
Display Webpages
The IP address is that of the computer being accessed. Use "vnc" instead of "afp" for screen sharing. This works really well at home. I have an icon for each computer and have them in a Stack on the Dock.

IMac won't wake with touch of mouse or allow remote connection when sleeping

My iMac will not wake with just the touch of the mouse any longer now that I have Mavericks. It did with Snow Leopard, but not with Mavericks. Now I have to hit a key on the keyboard or hit the mouse.
Also, when the computer does wake now, it take a while for the internet to connect again, the clock to update and my email to come into Outlook. When the mail does come in, the receipt time is wrong, of course.
In addition, I used to be able to connect from my windows laptop to the iMac through Filezilla even when the iMac was sleeping. I cannot do this with Mavericks. I have to physically go to the iMac and wake it up and then I can connect to it remotely. Kinda ruins the whole point.
I’ve made sure “Wake for network access” is checked in System Preferences > Energy Saver and I’ve made sure “Wake on Wireless: Supported” in there in System Information when accessed by Option + Apple icon.
How can I get my computer back to where it was- waking with only a touch of the mouse (not pressing keys) and accessing it remotely while sleeping?
I’m not a computer expert, obviously, so please explain any acronyms or jargon you might use when answering.
Thank you in advance for your help!

Thank you for your swift suggestion! I think it has worked I will monitor it for a couple of days

Is there any possibility to format an Imac without backing up all datas (re-install the OS without touching to Itunes-Iphoto-Safari Bookmarks etc.)?

Hi everyone,
I guess the question pretty much speaks for itself. My Imac is running very slow these past few months and I would like to reinstall the whole OS.
However, I would like to avoid loosing any data by formating the Imac without touching the user desk. Is that possible? And if so, what are te steps to proceed?
Thanks in advance for you help!

Formatting a drive is a destructive process, so you cannot format a drive without losing everything on the drive. But it is possible to reinstall OS X without reformatting the drive.
But you need to tell us what version of OS X is installed. I would recommend you backup your drive before such an action.

IMac 27 inch hum/buzz/vibration

I have just come from the new Apple store in Hornsby, having returned the second iMac 27 inch computer with a hum/buzz/vibration noise complaint.
APPLE THIS IS NOT A MYTH AND NOT ACCEPTABLE!
The story goes like this...
I bought a 3.4 Ghz, quad core 27 inch iMac with a 1TB Seagate HDD and 8GB of RAM, and the 1GB video card a few months ago from the Apple store in Castle Hill, Sydney NSW. Took the machine home, set it up, and was extremely happy with it. Upgraded to Lion, had no issues with performance or ambient noise etc... it was whisper quiet. I would leave the machine running all the time, letting it simply sleep when inactive, and it never made a sound other than the optical drive or maybe occasionally the drive heads when reading or writing data. It was dead silent!
I receieved an email from Apple stating that in some circumstances the Seagate drive could fail, and for me to contact a store to make an appointment to have the drive replaced as part of a product recall. I thought 'I'll do the right thing' and made an appointment with Castle Hill Apple store to see a 'Genius'. Here comes my first gripe! I am an IT professional myslef (a CIO with a technical background) I should add, at this point. When I made the appointment I was unable to ascertain the status of stock for the replacement hard drives or how long the replacement would take. I get to Castle Hill and I am advised that the drives are not in stock and it could take a few days to get this completed. I don't want to be without my new computer for that long!? So I take it home and rethink how I should approach this.
Hornsby Apple store opens! I live in Hornsby so that suits me! On talking to a representative at the Hornsby store just this Friday passed I am advised that they do have the 1TB replacement drives in stock so make an appointment quick smart! So I do. It goes downhill from here...
On Sunday just passed I drop my iMac (Serial # C02FG03YDMW8) with a Seagate 1TB HDD in for hard drive replacement. As my data needed to be transferred from one drive to the other, I was told it would take overnight. No problem I thought. All good. I pick up the iMac the next day, with the Seagate drive replaced with a Western Digital one, and take it home. Set it up and turn it on. Suddenly my iMac is no longer 'whisper quiet'. From the point the system status chord sounds there is a humming or buzzing 'droan' that resonates through the desk and can be heard even over my television, fridge and fish tank! Sitting in front of the iMac for more than 10 minutes results in discomfort from the sound. It didn't make this noise before!? My assumption was that the new drive was either faulty or incorrectly installed. Dissapointed, and informed by reading countless blogs and forums on others returning multiple iMacs with the same complaint, I box back up my iMac (which I had previously been VERY happy with - previous to it being a buzzing machine that was) and the next morning (Tuesday) return it to the Hornsby store.
At this point I must note that the staff (Manager Kate and Technician or 'Genius' James) have been outstanding in terms of customer support. I cannot fault the staff at this point, just the product.
Tuesday morning the folks at the Apple store advise that they can either try to repair my now noisy iMac, or replace it. I figure, well I'll replace it then. So James sets about that day transferring all my data again, moving my 8GB of Ram from the machine with serial number C02FG03YDMW8 to a new machine, with serial number C02FP02MDMW8. The new machine has in it of course, a Western Digital drive (not that I am attributing the hum/buzz/vibration to the WD drive, but it is an odd coincidence don't you think?). I pick that machine up Tuesday afternoon, thanking everyone for all their wonderful help, and knocking on wood that this new machine is as faultless as my first one was prior to the drive replacement. Guess what!? It wasn't!!!
So I return the second machine this morning. You guessed it... I am now irate. The 'Genius' told me he could not recreate the issue... OF COURSE! GENIUS! You have music in the background and it's a noisy store! I wish I had never let anyone touch my iMac in the first place. As I've said I've read countless forums on this issue - it DOES EXIST! If I pick up the machine when running, the buzz vanishes. You can FEEL the vibration through the stand. If you lean the machine forwards onto the front ledge of the stand the sound goes. It is something to do with a moving component that is creating a vibration and in quiet environments the noise actually becomes irritant. I left my iMac running overnight and from my bedroom, I could hear the droan. The desk is a wooden desk, on tiled floor - but I must impress, MY FIRST iMac DID NOT MAKE THIS DROAN!
Anyone wish to comment? Apple maybe!? The iMac is in the shop for further diagnostics.

I also have 2 Tb Hitachi iMac 2011 with SSD. The source of constant noise is Hitachi drive. When iMac runs just on SSD it's dead silent. Disappointed with this issue for so expensive model. Changing the tabble or using rubber pad like some people advice don't help at all. I saw some iMacs which are almost dead silent, so it's weird Apple sells so different models, especially when you pay much more to get that 2 Tb drive. I am already out of my 2 weeks return/exchange period, and actually I had a very little hope on the shop - they surely will tell it's normal since the drive is OK. I called Apple authorized service and they tell iMacs can be as loud as 30 Db. But it's weird, I saw a bottom line 512 Gb model in the shop and couldn't hear any buzz even with my ear touching the screen. Surely the constant HDD buzz just attracts the attention and makes overall impression from using iMac not that positive. I saw older iMacs, even plastic ones, they are all dead silent. So what can we do in this situation? Surely Apple won't serve it as a warranty issue. Also customers are very limited in choosing replacement hard drives as Apple now uses proprietary models, and many of them tend to be noisy....
Actually when you have an SSD drive you can unmount your second hard drive and it becomes silent. You can even specify the drives to go to sleep after 1 minute of inactivity with pmset Terminal command. But it will start to spin again again after going from sleep. Also if you have some third-party tools like Parallels installed, the second drive will not sleep at all cause Parallels causes some conflict.
Overall this computer is dead silent when the secondary HDD is not spinning, even in games.
I really don't know what to do

Frustratingly, since I upgraded to Yosemite 10.10, I too am having the worst problems with WiFi dropping out. I've never had this problem before on my iMac 27-inch mid 2011 model. Turning WiFi off and then back on again sometimes works. Help please.

Frustratingly, since I upgraded to Yosemite 10.10, I too am having the worst problems with WiFi dropping out. I've never had this problem before on my iMac 27-inch mid 2011 model. Turning WiFi off and then back on again sometimes works. Help please. I've already tried a lot of your suggested fixes, but without success. Why hasn't Apple Fixed this?

Please test after taking each of the following steps that you haven't already tried. Stop when the problem is resolved. Back up all data before making any changes.
Step 1
Take the applicable steps in this support article. The Wireless Diagnostics program generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 2
Disconnect all USB 3 devices. If you don't know which are USB 3, disconnect all USB devices except keyboard and mouse.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. If you find that Wi-Fi works better with Bluetooth disabled, you should use the 5 GHz Wi-Fi band. Your router may not support it; in that case, you need a new router.
Step 4
Open the Energy Saver pane in System Preferences and unlock the settings, if necessary. Select the Power Adapter tab, if there is one. Uncheck the box marked
Wake for Wi-Fi network access
if it's checked.
Step 5
Open the Network pane in System Preferences and make a note of your settings in the Wi-Fi service. It may be helpful to take screenshots of the various tabs in the preference pane. If the preference pane is locked, unlock it by clicking the padlock icon and entering your administrator password. Delete Wi-Fi from the service list on the left by selecting it and clicking the minus-sign button at the bottom. Then recreate the service by clicking the plus-sign button and following the prompts.
Step 6
In the Wi-Fi settings, select
Advanced... ▹ TCP/IP ▹ Configure IPv6: Link-local
Click OK and then Apply.
Step 7
Reset the System Management Controller.
Step 8
Reset the PRAM.
Step 9
Launch the Keychain Access application. Search for and delete all AirPort network password items that refer to the network. Make a note of the password first.
Step 10
Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

Imac 27-inch 10.9 recovery disk will not start

hello everyone,
I am having boot up problems on my imac 27-inch.
I pressed the power button and press and held the Option key, I chose the
Recovery disk, but the Recovery disk did not start, instead I have the grey Apple logo and it keeps running but will not start.
The imac 27-inch was bought refurbished in late 2010
I also have imac apple care from 2010 never used. First time problem.
On pressing the Option key during startup,
Mach Hard disk and Recovery Disk 10.9 is displayed.
Choosing mac hard disk does not boot up the OS instead I get a big Zero sign with line through it or a big flash question mark sign.
Choosing the Recovery Disk 10.9 does not boot up Disk Utility, instead I get the grey Apple logo.
Please help. Thanks.

Your Recovery HD is damaged. You may be able to repair it using Carbon Copy Cloner 3.5.4. Under the Windowm menu select Disk Center. Select your boot volume from the list. Click on the Recovery HD tab then click on the Create a Recovery volume for this disk. Select Mavericks from the dropdown menu labeled "Recovery HD version to be applied." See if that works. If it does not then see Update - Create Lion RecoveryHD Partition Quickly Without Reinstalling | brunerd. Or see Recovery Partition Creator 3.7 – Updated for Mavericks ...

For some reason My Imac will not wake up with bluetooth Trackpad or keyboard from being in sleep mode over night.

During the day it wakes up fine. this just happens on over night. I can press the power button on the Imac and screen wakes up but my trackpad or keyboard will not work. After I Restart my Imac by holding down the power button until it shuts down and then pressing to power back on it works right away. this starting happening about a week after Lion upgrade

I've been dealing with the same issue of not waking up from sleep. For a long while, I turned off the option entirely just so I wouldn't get mad at my computer. The difference with my setup, however, is that I use a USB keyboard w/ a USB mouse. I tried most the "solutions" that I've come across on these boards. What upsets me the most is the vast number of similar posts without a clear answer.
Anyways, since I use wired keyboard and mouse, I just turned bluetooth off on this computer and tried once more to wake it from sleep. Surprisingly, it worked. My suggestion, try a wired keyboard and mouse with Bluetooth disabled on the computer.
Edit: I spoke too soon. On the second attempt, it did not wake. For reference, that one single time that it woke up was the only time I've ever had my computer's display wake from sleep mode (like many, the computer wakes, but the display won't).
Here's to hoping that whatever is causing the problem is not around in Lion.

Automatically mount USB 3.0 WD External HDD with iMac 24-inch mid-2007

I am using a 2TB Western Digital (WD) My Book Essential external Hard Disk Drive for my iMac 24-inch mid-2007 to use it as a Time Machine backup disk. This HDD only comes with a USB 3.0 connection.
Function-wise, it works with the iMac and Time machine uses it for backup without any issues.
However, the following problem occurs at every restart: the HDD does not mount automatically. And Time Machine stops backuping. To make it work again, I have to either unplug/replug the power cable of the HDD or unplug/plug the USB cable of the HDD so it mounts again and can be used by Time Machine. When unmounted, I tried to see if the disk was at least visible in Disk Utility so I could mount it from there but it does not appear in Disk Utility until I physically unplug/plug it back again.
For troubleshooting purposes, I have tried to use this HDD with my MacBook Pro Retina 2013 and I don't have the same problem as the HDD mounts itself automatically when I restart.
So I assume the problem reside in the way the iMac mid-2007 handle USB 3.0 as it was probably manufactured before the USB 3.0 standard was developped.
Would anyone know a possible workaround for this issue? I don't have too many hopes but one never knows...

I am using Mavericks 10.9.1.
The problem was also occuring when I was running Mountain Lion.
It looks backward compatible to me except when it comes to automatically mount itself after a restart.

New iMac 24 inch, 2.93 GH problems with spotlight and finder

Has anyone had problems with Spotlight flickering in the upper right corner of the screen with each keystroke and the Finder crashing and relaunching when trying to open certain folders copied from an older computer running 10.4.11 or trying to open home folders on G5 and G4 computers over a local network? I have now received two replacements for my original machine from Amazon.com and all three machines have the same problem. This has been going on for nearly three weeks. I have never had problems like this with Apple products before - and have used them since 1985. Is there a design defect in the new 2.93 GH 24 inch iMac? I have been in touch with Apple Support but no one has resolved the problem and none of the product specialists are using this particular model of new computer. Very frustrating!

HI Edwin,
Check the iMac hard disk for errors. Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger and later) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.

2 days old imac 27 inch shows question marks on start up..help~

just got a new imac 27 inch two days...finally opened up the box today and start it up and now it show question marks on boot

or there is something i could try..any help would be appreciated

Try this:
Reinstalling Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion: Select Reinstall Lion/Mountain Lion and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

You can't erase the internal drive without an installation DVD or other system and still have an usable computer. Phone Apple Support and order replacements, or purchase a retail DVD compatible with your machine.

I have an iMac 20 inch early 2009 software osx 10.8.1(12b19)...i am not able to use my internet, outlook, or any messenger. tried troubleshooting, reseting safari, disabling firewall, deleted intego...still no internet

I have an iMac 20 inch early 2009 software osx 10.8.1(12b19)...i am not able to use my internet, outlook, or any messenger. tried troubleshooting, reseting safari, disabling norton firewall, deleted intego...still no internet. i did delete intego without uninstalling so im wondering if that caused the problem. everytime i try to open safari it displays this: Safari can't open the page: "http://www.yahoo.com/". the error is: "the operation couldn't be completed. Operation not permitted" (NSPOSIXErrorDomain:1)

Like nearly all antivirus utilities for OS X, Norton a/k/a Symantec and Intego are worthless junk that will cripple your Mac. Remants of one or both are most likely preventing Safari from communicating.
Search the forums for techniques to eradicate them - simply disabling them or dragging their apps to the Trash is not likely to be sufficient. Start by reading this procedure from Symantec:
http://www.symantec.com/business/support/index?page=content&id=TECH103489
For Intego: http://support2.intego.com/kb/index.php?x=&mod_id=2&id=214

I believe you are correct. Download and run its uninstaller.

TS4079 4s 's voice control and siri suddenly operate by themself without touching

Hi. My 4s 's voice control and siri suddenly operate by themself without touching the phone all the time. Tried to swiitch off and when reopen still status quo.Possible that my phone got virus? What should I do?

This is definitely not a virus. There is no known malware capable of infecting iOS, unless it has been jailbroken (ie, hacked to allow apps from outside the App Store).
First, try resetting your device. Press and hold both the home button and the sleep/wake button for about 10 seconds, until the screen turns off. Ignore the slider that will appear. Release the buttons, then press and hold the sleep/wake button until the Apple logo appears. This is the equivalent of a reboot, and should not affect your data or apps.
If that doesn't help, try restoring your device from backups, and if that doesn't help, restore it to factory settings (ie, do not restore a backup). See:
http://support.apple.com/kb/ht1414
If none of that helps, the issue is caused by some kind of hardware problem, and the device will need to be repaired or (more likely) replaced.
