Line in of Intel iMacs OK??

Hi,
for the last 3 years my eMac + Logic have been doing a great job as my recording equipment. I always use the line in of the eMac as audio interface, and I'm satisfied with it's quality (the same applies for it's predecessor, a G3 iMac).
Just curious: is the line input of the Intel iMac just as good?? And how does it work exactly? I'm reading something about a combined analog/digital connector???
Thanks!
Regards,
Jaap

its better. its optical so u can use both optical connects or the 3.5mm jack. this also makes 5.1 output via an optical cable possable

Greenish Vertical Lines in Intel imac 21.5" 2008

I have an intel Imac 21.5" 2008 that has some kind of cloudy greenish vertical lines in pairs all over the screen. Here is a photo http://imageshack.us/f/845/img0041wy.jpg/ Any ideas whats causing this?
I had the same problem about a year ago and apple care covered all expenses. Now that i dont have apple care I was hoping this was a quick fix or at least get an idea how much its gonna cost.
Any help would be awesome guys

Welcome to Apple Support Communities
I see the bars. Although it looks like a display issue, first reset the SMC > http://support.apple.com/kb/HT3964 Do the same with the PRAM > http://support.apple.com/kb/HT1379
If they don't work, the display is damaged. For hardware problems, there isn't a software solution, so the only thing you can do is to take it to an Apple Store or reseller.
I have never had any problem with my Late 2009 21'5-inch iMac, but in 2012, my GPU failed, I suspect because of high temperatures

06' Intel iMac: lines on screen

Howdy!
...I have a 2006 intel iMac (17" 2.0GHZ)...-it's been a trusty workhorse for years.
We recently started seeing vertical lines on the right side of the screen, just a few at first then a couple more down the center. Now there is a solid barrabout 1.5 inches wide down the left side of the screen. Im afraid that my mac is about to die
After researching the problem with various web forums i learned that this is a flaw in this particular model.
Does anybody know if Apple would be willing to fix this without charging me?...I've read in some cases they have done this for customers.
Any insight on this would be most appreciated!
Thanks!

Same problem with a 2006 iMac 17". Apple used to have a maintenance program (EM80) that would fix it, but Apple expired it in spring 2011. The support line said they were out of parts, unless you live in California, which apparently requires manufacturers to maintain parts for seven years! The stupidity of telling me that should be obvious. Also, the local Apple store quoted $600 to repair it. How they can do that if Apple is "out of parts" is beyond me.
The support desk did offer me $100 toward the purchase of a new iMac; the local store offered a 15% discount. From all the discussion and forums, it's obvious that this is a manufacturing or design issue and not a random event. Several thousand users have been impacted. I'm disappointed that Apple will not stand behind their products. Certainly makes me less likely to purchase another one.

What to do about vertical color lines on Intel iMac?

I have an early intel iMac (2006). A few months ago a yellow vertical line appeared on screen. Now there are 5, all different colors. Is this a sign of impending doom?

It sounds like your graphics card, which is attached to the logic board, may be failing. You may want to run it into an Apple Store for a Genius's opinion.
Hope this helps

Bottom line: Anyone get an Intel iMac yet?

Hi,
Let's cut right to the chase. Has anyone received any of the Intel iMacs yet?
If so, please test it ou for all of us and report your findings. If you will receive soon, please do the same and report your findings.
The Apple Store does not have any of these on display. Kind of weird since it was available yesterday. Wouldn't the store have gotten them that day so they can demo them for customers?
I am dying to find out as much info on these machines before I buy.
Thanks,
Michael

I just ordered mine 10 minutes ago with 2GB RAM, 256MB video on a 20". It came out to exactly $2,099.96 with education discount and California tax. Mine is estimated to ship within 3-5 days. I can't wait! I hope they are being conservative with their shipping estimate like everything else I've ordered from Apple and my new iMac gets here next week!
I'll post my experiences as soon as I get it!

Intel iMac stuck in reboot loop

Since the last few days, my 6 month old Intel iMac is stuck in a reboot loop.
Configuration:
Model Name:          iMac
Model Identifier:          iMac12,1
Processor Name:          Intel Core i5
Processor Speed:          2.5 GHz
Number of Processors:          1
Total Number of Cores:          4
OS: 10.6.8 (with patches applied as they become avaliable)
It is connected to a UPS at all times.
I always put it to sleep at night. Sometimes it stays in the Sleep mode for a couple of days (i travel and wife does not use for some time). But it always would "wake" up from Sleep on a keyboard touch. Magic mouse battery died a few days ago, so put in a new pair of battery, had the usual problem of "pairing", fixed that and continued on.
(Coincidentally, it almost also marks where my problems started).
Now, when i press any key, the iMac reboots. And then just before it looks like it will show the wallpaper, it reboots. and this continues on - sometimes 10-15 times. I press the power key and switch it OFF. Press the power key again, no go - stuck in the reboot loop. Run the Apple Hardware Test (exhaustive one included - it reports no issue found). Do a SMC reset (take off the power cord from the back of the iMac for 35 seconds) and put it back. Switch off the mouse and attach a USB mouse and press the Shift key to boot into the Safe mode. This works! Installed Pacifist to check for any non-Apple kernel extensions, none found...
Since AHT reports all fine - can hardware be ruled out?
Could it be the magic mouse? Need to try it (just wary of the reboot loop )?
If it is the mouse, is it covered in the 12 month initial warranty (I am in India)?

Intel iMac - won't start - grey screen & progress bar

I have a 2006 Intel iMac - 20" model, Intel Core Duo, 2GHz, 2GB RAM, 250GB HDD, etc. It was one of the very earliest Intel iMacs. Kept updated, running OS 10.6, etc.
It has worked extremely well for over 5 years - apart from the Superdrive being temperamental sometimes - but has suddenly gone wrong.
Last week the machine completely froze for no apparent reason. I had to force a reboot. This failed - grey screen and the grey spinning wheel (if that's what it's called), indefinitely.
Forced reboot again and this time held down the shift key to go into safe boot mode. This time it was successful, and I was able to get to the logon screen & log myself in. I opened Disk Utility & attempted to do some diagnostics but the machine froze again.
Looking around various other forum postings...I rebooted the machine in single user mode and was able to get to the command line to type 'fsck -fy' to attempt to fix disk problems. This failed repeatedly, with an error message 'invalid node structure'.
I tried to boot my machine from the OS X disc but my Superdrive refused to play ball - it would not read the disc (or any other disc for that matter, including a copy of DiskWarrior that I have).
I have now got hold of an external DVD drive in the hope that this would show up as a boot device when I switch the machine on while holding the option key down. No such luck - the drive powers up ok (power via USB) but I'm not given the option to boot from it - in fact that screen doesn't appear at all.
All that happens now on powering up - regardless of what I do - is the grey apple symbol appears and a progress bar beneath it. The progress bar gets stuck about 5% of the way along, and then after about 10 minutes it disappears and is replaced with the grey spinning wheel thingy. And then it just gets stuck - nothing else happens.
HELP!
All my important data is backed up on an external drive via Time Machine, so that should be safe, but I'm desperate to get the machine running again.
One thing that occurred to me is that I've had a program called ReFit installed on the machine which allowed me to run the machine as dual boot etc. (and I do have a couple of other small partitions on the drive, not currently used) but the ReFit welcome screen stopped appearing a couple of weeks ago for some reason. I'm wondering if this has somehow messed things up...?
Grateful for any suggestions...
Thanks,
Alan.

For the drive, you should be OK with any SATA 2 at 3 MB/s transfer speed. You could also use a SATA 1, no jumpers needed. (Not SATA 3 - can't be jumpered down.) The early 2006 Intels were 1.5 MB/s -- at least the drives were, so I'm assuming the SATA controller on the logic board was also. Might just be SATA 2 hadn't yet been introduced and can run the faster SATA 3 without jumpers. My guess is not. You should be able to set jumpers on the drive for backwards compatibility. You'll have to contact the drive manufacturer or go to their website for that info.
http://www.everymac.com/systems/apple/imac/stats/imac-core-2-duo-2.16-20-inch-sp ecs.html
As for the superdrive, I'd contact the manufacturer to check on compatibility.
Glad I'm able to help. BTW, in case you haven't noticed, maybe you want to have a look here.

Intel imac display glitch and involuntary restart

Just want to know if anyone else has experienced this specific problem, there are plenty of complaints about intel imac displays but I can't be bothered to sift through them all trying to find a match for my problem.
A couple of months ago I was watching a video in quicktime and noticed that my screen was glitching and flashing fragmented diagonal lines - like a commodore 64 loading type thing. Then the spinning-ball came up and a force quit didn't do anything so I had to force shut down. I started up and it occured again. Then the screen went blank/black, but still lit up, and restarted without me doing anything. It also got stuck during start up the second time this occured. I panicked and ran out to buy a 500GB external drive, backed up all of my work and then re-installed mac osx from disk, archive and install job. This seemed to sort it and for the following two months it seemed OK. No sign of any problems.
Since then I have updated from 10.4.7 to 10.4.10 (which I have suspicion that it screwed the firmware in my motu 828 firewire audio interface, costing me a £130 repair - but that's another painful story).
It happened again tonight (the screen thing, not the motu). And the ball came up and I couldn't do anything. Force shut down, restart - screen glitching again. Then I had 2 unexpected restarts, one getting stuck in startup. Then a successful startup but accompanied by the glitchy graphics, mainly red/pink pixellated diagonal lines flickering in and out. I ran a disk first aid - no problems. Did a disk permission repair. Shut down and ran a hardware test, the first few minutes of the test the screen was still at it but then stopped glitching, hardware test found no errors (it was an extended test too). Now I'm back on it and it's all OK.
Any suggestions/similar stories?
When it occured 2 months ago I had the original ram that came with the imac. Now I have 2x1GB sticks of crucial ram.

That's it! Well, that's what I have. Unfortunately, I don't know about the cause, but I don't ever recall having it prior to an update going back about a year ago. I recall an update, and that update being immediately followed by some sort of Apple Graphics something-or-other. I feel pretty certain that's when I first noticed this. I just had my LCD replaced for another reason, but I think you'll agree, it's not an LCD issue. In my case, browser activity, scrolling up or down in a page, seems to be the most common trigger. I've also seen "pieces" of the torn page, on the screen when minimizing the browser to the dock (usually Firefox, but I think I've seen it with Opera and Safari too). Is there a way to find update packages installed somewhere? I'd know it if I saw it, and I'd definitely try removing that suspect package/update.

Intel iMac freezes, reboots and other issues

Intel iMac 17" 1.83 Ghz model (Had for a while now)
1 GB of 667 MHz DDR2 SDRAM installed (Mac detects this fine)
Mac OS X 10.4.8
Beginning yesterday, the Mac froze when shutting World of Warcraft (which had been installed and working for at least two months). Computer completely hung. Restarted machine.
A few minutes later, the machine just switched itself off (or appeared to) - screen goes black. I held in power button for five seconds until I heard a click in the machine. This has happened repeatedly.
One time, the machine froze and the monitor refreshed at a visible rate (I could see the scan line) - each time the screen got darker.
Often, it will turn on, but the OS won't load unless I hold Alt down, or if I use OptionAlt+PR.
Ran disk utility from the install disk, only minor issues, all fixed. The problem of turning off still occurred.
Nothing in the kernel panic log. Diagnostics in System Profiler is saying it passes on the power on self test.
The confusing thing is, that after last night, I pulled the plug out, went to bed, praying to the computer fairy to fix it. This morning, it ran fine continuously for about 8 hours, running WoW, IRC app, iTunes etc. all fine.
Could it be a power supply issue? Is the thing overheating (the Mac is up to date with EFI Firmware update and SFC Firmware update).
I'm utterly stumped as to what's causing it. I don't want to send the thing off as then I'm without a computer.
Any ideas or advice?

Has it done it since?

Intel iMac will not boot past gray screen

Intel iMac will not boot past gray screen
my system:
new (month old) 24" intel imac, 2.8 ghz, 4 gb ram.
running: leopard (upgraded from tiger, which was pre-installed at purchase), installed 10.5.1 update right before this huge problem occurred.
install discs on-hand: two-disc tiget set, single leopard upgrade disc.
what led to this:
i wanted to install windows using bootcamp on a 50 gb partition.
at this point i was running leopard 10.5
i followed all bootcamp instructions, printing out the guide, as well. once i got into the windows setup, i was prompted to choose a partition to install windows. unlike the bootcamp guide, which showed three partitions, one clearly labeled "bootcamp", i saw only one partition. not wanting to risk writing over my mac partition, i quit the setup and rebooted the mac os. after some googling around, i looked for firmware updates (didn't need any), and then software updates. i decided to try updating to 10.5.1.
i then ran through boot camp again, deleting my previous windows partition, creating a new one, and moving forward as before. once again, i was only shown one partition to choose from in the windows setup. i exited the setup again to reboot through the mac os, but this time, i was only given a blank gray screen.
here's what i have tried so far:
booting from a CD, holding down the C or D keys: no response (in fact, i have to restart the computer holding down the mouse button to be able to eject the CD)
booting with option key held down: gray screen
booting with option key held down with external bootable firewire drive attached: the firewire drive appears as a boot icon, and i can click on it within a five second window, but then the screen freezes after that time period, and nothing changes
booting into target mode while attached to another mac: gray screen (no firewire icon, and drive never shows up on other mac)
resetting NVRAM: i'm able to hear the boot chimes, but no difference in performance. gray screen every time
Safe boot: nothing but a gray screen
Verbose mode: gray screen
Single user mode: gray screen
Single user mode with firewire drive attached: occasionally (not every time), i am able to get the white on black terminal to show up. from here, i'm able to run fsck, but it appears to only be checking the firewire drive. i have tried several times to boot from here, and once it took me to a blue screen with movable arrow cursor, but it never went beyond this.
is there anything else left to try before taking it to apple?
any help would be greatly appreciated.
thanks,

I'd call Apple support at this point. You'll need
to put this issue on the record.
Call U.S. iPod and Mac technical support: 1-800-APL-CARE (1-800-275-2273)
The wait may be long for an agent to come on the line
so expect that and have some other stuff to do in the meantime.
If you have the applecare protection plan, I'd ask about "onsite"
service.
I like your work ! Good luck !

Is it possible to put an iMac G5 screen into a intel iMac of the same size?

my white 17" intel imac screen is about 60% covered with the vertical line problem, ive tried openeing it
and blowing air through it, in hopes it was just some crazy dust accumulation, and smc fan control, but its getting worse by the week.
i have a g5 imac 17" with a perfect screen, but a dead HD so i dont use it,
can i get my G5 screen taken out and put into my intel?
id think it would be possible since their the same same size screen for the same type of imac
unless the the inner connections, placement etc. is different between the two.
thanks

heres a picture of my intel screen

Shane B,
I have the same model iMac with the same problem screen.
It's the LCD panel that is defective,(at least in my case).
You can validate this by getting a mini DVI adapter to connect the iMac to an external screen and test it on your HDTV or on any external screen.
Get the proper adapter from Mini DVI to what you have on the external screen or TV (HDMI, DVI, VGA)
and a cable to connect it and see if the image on the external screen or TV is OK.
In my case, my iMac was sitting on a shelf for two years before I thought of trying this.
I am now using it as a media server linked to my HDTV.
I ended up opening the iMac case to disconnect the LCD so I would not have to look at the ugly defective display sitting right next to my HDTV.

Intel iMac not reading time correctly

G'day
This is pretty desperate. I've got a 3000+ line applescript that automates a mail room for a large company.
They want to buy an intel iMac to exclusively run the script, but the script uses time based files for error reporting.
On my intel iMac the files read as 1st January 1904 12.00.00 am not matter what I do.
Are Apple fixing this, or is there a workaround?
Regards, Santa

Thanks red_menace. The test script I ended up with is as follows...
my Timer()
my displayInfo()
on Timer()
copy (current date) - (time to GMT) to tempDate
-- For universal time
copy tempDate to KeepTheTime
-- For an invisible file, put a full stop in front of the name ie ".Timer"
set t to my ReadTheTime("Timer", KeepTheTime)
display dialog "elapsed : " & my setTheDaysHoursMinutesSeconds(KeepTheTime - t) buttons {"OK", "See elapsed time", "Reset Timer"}
set temp to button returned of the result
if temp = "Reset Timer" then
copy (current date) - (time to GMT) to tempDate -- For universal time
my SaveTheTime("Timer", tempDate)
my Timer()
else
if temp = "See elapsed time" then my Timer()
end if
end Timer
on displayInfo()
copy (current date) - (time to GMT) to tempDate -- For universal time
copy tempDate to KeepTheTime
set time of tempDate to 0
set dayelapsedtime to KeepTheTime - tempDate
set day of tempDate to 1
set monthelapsedtime to KeepTheTime - tempDate
set month of tempDate to 1
set yearlyelapsedtime to KeepTheTime - tempDate

Apple aware of video problem in the new Intel iMacs

Macworld Daily News
Thursday - February 09, 2006
Apple investigates Intel iMac Front Row problems
By Macworld staff
Apple has confirmed it is aware of, and investigating, reports of video problems in the new Intel iMacs.
Recent reports claimed that some users had experienced random horizontal lines and other video playback problems when playing video in Front Row.
"Apple is aware of this issue and is looking into it," the company said in an email to a web-based pressure group that has been gathering information on the problem. "If a customer has any technical issues, they should contact AppleCare."
The problem is allegedly software-based.

"Sure, I'd be more understanding had it been an issue that required a very special set of conditions to trigger"
Apparently it does as this issue is not affecting all users.
"As I was told, affected owners would not be proactively notified"
Where you you prefer them to use their limited resources, trying to figure out who MAY be affected and sending them some sort of detailed action plan, or spending the resources determining the cause of the issue and developing a solution that can be distributed to the ones who need it not only now, but those that may discover the issue next week?
I can understand that you are frustrated, and don't blame you for feeling that way, but this is an all new piece of technology and bugs are going to come up that were missed in testing. No company can afford to test at a 100% level. To do so would drive the costs so high as to make it impossible to sell the product, especially to the market the iMac is aimed at. Apple has a pretty darned good track record of resolving issues quickly when they appear. Until they do you only have a few choices. Use the workaround until the solution appears, waste time complaining about it, or sell the iMac and purchase a different product. That's really about all you can do!
It was good of you to spend your valuable time, and yes it is valuable, trying to help the engineers or service reps solve the issue. That they spent that much time with you should show their commitment to solving this issue.
Be patient, give them a chance, they have not had long to try and figure this out.

Bluetooth Not Available 10.7.2 2011 Intel iMac

Hi Guys,
I need a little advice whether I have a software issue or Hardware issue with my (May 2011) intel iMac (27")
When I got the new iMac I migrated from old iMac with Snow Leopard and had no bluetooth issues at all.
I upgraded to Lion in July and Bluetooth was OK, 10.7.1 update seemed ok until 2/3 weeks ago, 10.7.2 has had no fix.
This is the problem:
I have an Apple BT Keyboard, BT Magic Mouse & BT Magic Trackpad connected... all was ok untl 2/3 weeks ago.
Currently on the 'top bar' if I click on the BT icon, it says "Bluetooth: Not Available" ...... The BT icon itself has a 'jagged line' through it.
Bluetooth is not shown under System Preferences.. as if it does not appear on my iMac
Also if I check under 'System Information' and click on Bluetooth it says "No Information Found"
I have reset the PRAM and SMC & Verified and repaired HD several times.... all to no avail.
I have favourited the BT devices to the iMac allowed them to wake iMac etc, but does not offer a fix.
Over the last few days it magically comes back on for a while then cuts dead in the middle of 'work'.
What should my next step be?
Thank you very much in advance for any advice offered.
PS:
I have checked the Console.App and have a Kernel log file with these 'panics', I admit this log is way beyond me but if anyone understands it, I'd be grateful:

Hi elcroz, were you able to fix the issue eventually? Was it a hardware problem? I'm seeing the same behaviour since yesterday (also on a mid 2011 iMac).
When I woke the iMac from sleep yesterday Bluetooth was "gone" - no connection to mouse and keyboard and the module had disappeared from System Preferences. I rebooted and the Mac booted itself into safe mode. I did a PRAM reset and that instantly solved the issue. But today I saw the exact same thing again, only that the Mac wouldn't even respond to my old USB mouse when I connected it. After a hard shutdown and restart everything seems fine… Bluetooth available and functioning. What the **** is going on here?
I just performed the Apple Hardware test and no problems were found.
I'm seeing some of the same errors in console you pasted, but only one line of each after a restart.
Strangely my keyboard was mentioned in the console logs and my mouse wasn't - so I will keep using a USB keyboard for now to see how it goes.
Anyway, I would really appreciate any advice - let me know how it turned out for you, if you get the chance. I don't want to bring the Mac to an ASP if it's not really necessary, the nearest one is more than an hour away from where I am….
Cheers

Line in of Intel iMacs OK??
