IMac (late 2006) model failing to boot

Hi Everyone,
I have a 24 inch Intel iMac (late 2006) that has just died.
Running Command-V on boot up I get the following output in the console:
efiboot loaded from device: Acpi (PNP0a03,0)/Pci (1F|2)/SATA(2,0)/HD (Part2,Sig9EBFBCBB-9....
boot file path: \System\Library\CoreServices\boot.efi
.Loading kernel cache file 'System\Library\Caches\com.apple.kernel caches\kernelcache.1713EAB3'
Couldn't get file info.
Loading 'mach_kernel'...
.Error loading kernel 'mach_kernel' (0x80000012)
What is going on here? I put in my Leopard DVD and booted with the Option key down. The first time only the DVD appeared as a boot option. When I booted into the DVD I couldn't see the Hard disk with the System Profiler or Disk Utility Could only see the DVD).
After a few reboots the Hard disk suddenly appeared on holding down Option during bootup. Now I could see also see it in the Disk Utility. I tried to run Repair Disk and it just hangs.
Is this a faulty drive or perhaps a loose SATA connection? From the Terminal I can go to \Volumes\Macintosh HD\Users etc and see files but as I go down the directory tree it starts to go very slow and after a while an ls command gives no response.
Very strange behaviour. Any advice would be most welcome. I am thinking the drive has gone but I don't want to replace it if I don't have to. Luckily I am backed up up until a month ago with Time Machine, however there are a couple of things I would like to recover off this disk.
Thanks again,
Matzuber

smarkt,
Welcome to Apple Discussions.
It appears your internal HD has failed or is on it's last legs so it's time to replace it. If you have any Apple Care left you can get it covered under warranty however if you don't then I'd recommend you take it in to be replaced. You can use this link for locating an Apple Authorized Service Provider. The good news you have a backup of your important files.
As far as the remaining information you want to save that will depend on the condition of the existing internal HD. You may have to resort to a data recovery service (worst case) or if it's still got a little life in it you can put it in an enclosure and once the new HD is in your iMac move information to the new HD or your external HD.
Best or luck,
Roger

Late 2006 iMac graphics problem, system freezes
http://www.youtube.com/watch?v=3j-tZ_v1aCc&feature=plcp

Imac (late 2006 version) couldn't boot

On last Monday night I couldn't login to OS in my imac all of a sudden, it just freezed in the grey screen with an apple and spinning logo and I had to hold the power button for a few second to switch it off. I managed to login in safe mode and then had a quick backup of my important files to external harddisk, then I shut it down and went to sleep.
On Tuesday night I tried to switch the imac on in normal mode,it failed. On safe mode again, it failed. This time it was not just freeze in the grey screen, it even shut itself down suddenly when things were loading.
I was totally freaked out and searched around the web for every possible causes. Followed by some suggestions I have run the "Apple Hardware Test" from the OS 10.4 Install Disc, and it said "No problem found". Then by Disk Utilities it said my volume could not be repaired. (Image for ref: http://www.flickr.com/photos/smarktie/4782847981/)
What else can I do?
I really don't want to erase everything to install OS again. I only had my important files backup but there're still a lot of other data in the imac. My OS system have been upgraded to 10.5 a year ago. And actually I've already purchased the installation disc of Snow Leopard and planned to upgrade the system within a week after I buy a new external harddisk to run time machine.
But now all I want is to keep all my files save......
Is there anyone can help? Thanks very much!

My iMac (late 2006) no longer boots from FireWire drives, although they contain all the system files.

My iMac (late 2006) no longer starts (boots) from Firewire drives, although they all contain a current system (Mac OS X 10.6.7). If the drives are connected with USB 2, they boot normally. The FireWire drives appear in the Start Volume program, but they do not boot. If I press and hold the Alt key while booting, only the internal drives and the USB drives appear as options. What can I do in order to boot from FireWire drives as I always could in the past?

I'd first recommend doing a SMC reset and if that doesn't work refer to:
http://reviews.cnet.com/8301-13727_7-10333969-263.html
and
http://www.thexlab.com/faqs/firewiretroubleshooting.html
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.

I contacted the online support but they have not been able to give me an explanation...

IMac Late 2006 shutting off

My iMac Late 2006 started randomly shutting off about a couple months ago. It would normally turn right back on and work fine. Now I cannot get it to turn on at all. I've tried many different power outlets, and I tried resetting all the power stuff with no results. On a rare occasion, it will turn on after pressing the power button over a hundred times. The Apple Store told me the iMac is vintage and they cannot fix it.
I want to know what the issue could be. Apple said it might be either the power supply or the logic board. Has anyone else experienced this? If its the power supply then I will go ahead and fix it but fixing the logic board won't be worth it.
What should I do?

Given the vintage of your machine, the problem could be anything.
Power supply issues have a specific profile. Your machine suddenly turns off. You reboot, and it works a while, but lasts a shorter amount of time. Reboot it, and the time will decrease. In this case, the only option is to get the power supply replaced.
Logic board has a wide variety of symptoms, depending on the model of your computer. Your issue is not inconsistent with logic board problems.
As RRFS counsels, getting a new computer will be more cost-effective than repairing the old one. Be sure to back your data regularly, of course.

Video tearing on iMac (Late 2006)

Hi,
My iMac has been suffering from what i think is video-tearing and horrible refreshrate for a week now. I'm thinking hardware problems.
The video-tearing mainly comes up when the screensaver goes on but it's still annoying.
The refreshrate is always bad.
I have the iMac(late 2006) 2.16GHz with 2GB ram and the ATI Radeon X1600 with 128MB VRAM.
What to do?

Same Model, same problem here. Much worse i think, picture cuts in half, fonts break. Happened after some update back in March. I was away for some time not using it but now few updates later still no resolution, Display looks fine in XP (bootcamp)

HT5634 iMac (Late 2006 20") with IOS Lion installed Windows 8 via BootCamp4, Then Upgrade to 8.1 Pro. Worked with warning message until today. How do I get out of Windows 8.1 to get back to IOS Lion.

Until today I was able to ignore the compatability issues warning (I know bad idea to ignore warnings) and move between IOS Lion and Windows 8.1 Pro partitions on my 20" iMac (Late 2006) with Intel processor. After restarting Windows and spending 1/2 hour waiting for it to update (after installing Office 365) Window works fine, but when I activiate BootCamp (from Windows) nothing happens. It opens and gives me the warning with the option to run the program anyway (like always) but it the program never starts. It stays in Windows. How do I get back to IOS 7 Lion so I can upgrade BootCamp 4 to BootCamp 5 which I just saw today as the solution...?

Power off your computer. Power up your computer, during power up press and hold the option key. When the boot manager appears select OSx.

My iMac (late 2010 model) desktop's hard drive is fried (was about 200GB). How much am I expecting to pay for a new one and retrieve my information?

As you can see Erin, trying to recover information from a hosed drive can be very expensive.
I would suggest first the OWC site as well. You can get a new drive of choice in size there.
I would also get the voyager http://eshop.macsales.com/item/Newer%20Technology/VOYQHDB1.0T/
and..
http://eshop.macsales.com/item/Prosoft%20Engineering/DGDR3BUN/
http://eshop.macsales.com/item/NewerTech/TOOLKIT11/
Wth your lap top and these folllowing tools your are set to change out the drive, reload OS and then with
the voyager pop in the old iMac drive and with the Prosoft software, try to mount and recover the files. Data Rescue is very good at this " if " the drive is not totally mechanically hosed. Drive Genius is very good at a number of things too. Nothing replaces the old adage of Back Up Back up Back up.
The voyage I listed can become the new backup drive for you.. your choice of tools: Time Machine or by cloning via CarbonCopyCloner or by what I use SuperDuper! IF you want to be really kewl.. both. By that I mean cloning and Time Machine.
It will take you an hour to swap out the drive and spring clean the iMac.. there is a hundred how too,s on you tube.
Hope this helps. Remember if is always when a drive will fail..they all do. I tell the people I support that Harddrives are good for 15 min.. to when they don't work. They will all fail.
Apple Geniuses are very limited to what they can and will do as far as file recovery.
Your best bet is to try to do it your self first. There is lots of help out here and you are not the first.

Memory upgrade on iMac (Late 2006)

I want to upgrade the memory on my iMac (Late 2006). My present memory is 1GB 667 MHz DDR2 SDRAM. I am getting that information from the System Profiler. That (one) module is in one Memory Slot, and the other Memory Slot is empty.
The manual says the following:
+Your iMac comes with at least 1 GB of Double Data Rate 2 (DDR2) Synchronous+
+Dynamic Random Access (SDRAM) memory installed. You can add 1 or 2 gigabyte (GB)+
+memory modules for a maximum of 3 GB of memory. Memory modules must meet the+
+following specifications:+
+* Small Outline Dual Inline Memory Module (SO-DIMM) format+
+* 667 MHz, PC2-5300, DDR2 compliant (also referred to as DDR2 667)+
+* Unbuffered and unregistered+
And it also says the following:
+Your iMac has a top slot and a bottom memory slot. You can add a memory module to+
+the bottom slot and remove the memory module in the top slot to replace the+
+installed memory. You can add a 1 GB or 2 GB memory module for a maximum of 3 GB+
+of memory.+
I guess I should just do as Apple suggests and add a 2GB module to the other memory slot, to maximize the total memory in the computer at 3GB. But does anybody have any alternative experiences or suggestions? Should I perhaps add another 1GB module to the other Memory Slot so that they are both equal? Has anybody tried adding 2GB to each Memory Slot? What happens? It seems odd or unbalanced to have a 1GB module and a 2GB module as Apple suggests. Any opinions from people experienced in this would be welcome, and I thank you in advance.

Hi rosalarose
To check how much memory you have and your memory usage go to: Applications > Utilities > Activity Monitor and select System Memory.
Your problem sounds more like a Software problem with Safari than a Hardware issue with the Memory. Instead of piggybacking on someone else's thread you should post a New Topic of your own here or in the Safari section of the Forum with a more detailed explanation of your problem.

IMac (late 2006) SSD upgrade

hi there!
after almost 6 years, the HD in my iMac late 2006 / 17" / Core 2 Duo died. At first, I wanted to replace it with another 3,5" HD but then discovered that an SSD would be the better option. I've found a couple of SSDs with a desktop uprage kit which takes them to 3,5". In the description however, it says that they are 6 Gbps. I always thought that the iMac can only deal with 3Gbps. Can I put this SSD into the machine or are problems going to occur?
thanks for your help!

While SSD's are supposed to be backwards compatible, that doesn't always work. I put an OWC 6G/bits per sec (SATA III) SSD into our 2010 mac mini, which supports SATA II speeds of 3G/bits per sec, and when it came up, I was only seeing SATA I 1.5Gbits sec speeds - yuk! OWC told me I needed to use their 3G/Bits sec SATA II SSD, and were helpful with the return and new SSD shipment. Works like a charm now at 3G/bits sec speed.
Not saying you'll have the same experience, however, I would recommend OWC and their SSD's, especially since they have a liberal 30 day trial period.

Not sure that I have selected the correct forum. Hope my questions are clearly stated.
Having problems connecting iMac(late 2006) running 10.7.5 to a Samsung Flat Screen TV using separate audio/speaker cable and HDMI standard cable, mini-DVI to HDMI video converter. TV displays generic Apple galaxy background and "some" windows (e.g. screen resolution choices). It does not show Mail or Safari menus. System preferences' display "gathered" the Samsung and chose its resolution. I did not find a way to select the Samsung as my display.
In addition to having old hardware, we have Verizon FIOS providing internet and TV access. Is there any way to make this work for us? We would like to stream video (Netflix) and view shows from the Web. Do we need Apple TV to do this? Or is it not possible with our old iMac? My husband thinks that our Airport could be a factor.
Thank you

Lately, I have been seeing a lot of posts with users trying to use their Macs/iMacs to mirror their streaming video from their Macs to an HDTV.
There are, actually, many alternatives to choose from than just from a Mac.
You need to have or invest in a WiFi capable router for all of these examples.
Apple TV only integrates with WiFi and newer Mac hardware. So, if you want to have total integrated experience, if you have a 2011 Mac or newer, you might as well pay the $100 for the AppleTV box.
If you have a older Mac, like I have noticed many users do, then you have other options.
If you want to elimate long cable clutter and having your Mac at the mercy of your TV all of the time, you can still use the AppleTV box independently or purchase cheaper alternative media streaming boxes from Roku, Sony, Boxee or any number of electronics manufacturers that now have media streaming boxes and media streaming capability built into DVD/Blu-ray players.
These eliminate long cable clutter by being close to the HDTV where shorter, less expensive cables can be used.
Another alternative for iPad users is to use an iPad with the USB/HDMI video adapter and use your iPad as the streaming box. This ties up your iPad in much the same way as it does with your Mac, but again the iPad can be close to the TV and use minimal cables to the TV.
Another alternative to is to use a combination of an iPad and your Mac to stream content that is only available to stream online from a computer. In this case, you can use a desktop remote app on your iPad and Mac. A good and cheap Desktop Remote app is Splashtop Remote. This allows you to completely connect your iPad remotely, over Wifi, to your iMac desktop. The app streams both video and sound to the iPad which is still connected to your HDTV. The resultant stream video picture will be smaller than the size of your HDTV, but it will still be plenty large enough to watch. Again, if you own a iPad and an Intel Mac, this method also allows minimal cabling to the TV.
