Video anomolies during boot screen on new iMac

I could not decide where to post this, but I thought it made more sense here than displays as you will see.
I got a brand new Core Duo iMac 17" and when I turned it on initially, the screen was completely garbled. Nothing was legible, it was just fuzzy video. The chime sounded normally. I cut the power and did it again. This time the display was still garbled but I could make out the apple logo on the gray screen.
When it booted into OS X and the initial setup it looked fine. After doing the "transfer your mac" and finishing registration, I shut it down completely and turned it back on twice and it did not exhibit this behavior.
I am not comfortable with the EFI/BIOS/whatever screen looking like this. Is this something that happens with new machines out of the box? Or is it definitely indicative of an issue with the video card or motherboard?
I guess what I am asking is if I should nip this in the bud or not worry about it.

This has yet to occur since the initial boot up, so I am marking it as answered.

  • No Apple boot screen on new iMac - Just black with white writing on boot

    Hi All,
    I have just purchased a new 3.06Ghz iMac and whenever I turn it on, or shut down, I do not get the Apple boot screen, I just get a black screen with a long list of white writing on it. This appears for about 5 seconds and then the usual desktop loads.
    Is there a way that I can get the usual apple boot screen to return? I have not done anything to the machine as it is brand new out of the box and it has been doing this since first boot.
    Any help would be greatly appreciated.
    Luca

    It was just a simple case of removing the verbose boot settings which I found a script for after searching on Google.

  • Macbook Pro 17" restarting during boot screen

    This seems to be an on going problem for people. From the threads I've read I could not get a solution.
    My Macbook is turing on and plating the chime, but the screen has been covered in loads of  square patches of purple dots. The Apple logo appears on the grey screen and the wheel starts to turn. What happens is it will do this for a minute or so and then freeze or more often restart and do the same thing again until i force it to turn off.
    I have tried all of the below already
         - Safe Mode (fails and restarts)
         - Single user mode (disk repair command as I could not do it through the graphical interface)
         - Reset using cmd+option+r+p
         - Recovery by holding Option during boot (again freezes or restarts)
    I would use a disc to a reinstall but my optical drive is broken and I do not have access to an external one. I realise I can use a Bootable USB but I only have access to a Windows for the time being. Its probably worth mentioning that was watching a video on Youtube when the whole laptop froze and starting repeating and jerking and then shut down. It has not worked since!
    Can anyone suggest any other posible solutions please?
    Thank you

    This seems like a hardware issue.
    All we can suggest is run a #3 Hardware Test, write down what it says and take it into Apple for a free eval.

    5 year old machine? I'd say it's the video card going because the cooling fins behind the fans haven't been cleaned, heat damage is irreversible.
    Not worth fixing, buy a new machine.
    You can extract the drive and use a SATA to USB adatpter and Migration Assistant to a new Mac.

  • Older iMac hard drive in enclosure won't boot long to new iMac?

    I have just received my new iMac i7 with the THIN case.....it is pretty awesome! I removed the hard drive from my previous iMac (2006 Intel core 2 duo) and put it into an enclosure hoping to retreive my old files. Here is the problem.....the old hard drive (250GB) will not stay booted long enough to transfer my files. The enclosure is a Sabrent 3.5" SATA hard drive USB 3.0 enclosure. It will appear for approx. 20-30 seconds, and then the message:
    "The disk was not ejected properly. If possible, always eject a disk before unplugging it or turning it off. To eject a disk, select it in the Finder and choose File > Eject. The next time you connect the disk, Mac OS X will attempt to repair any damage to the information on the disk."
    It will disappear from the desktop and I am unable to access it any longer. I am able to open the older hard drive and can open older folders, etc. while it is mounted on the desktop.
    A little background on the older iMac.....it quit working completely, would not turn on, no fan noise, no hard drive spinning, NOTHING. I ordered a replacement power supply and installed it......but still nothing. I can only assume the logic board is dead. Since it was what the genious at the Apple store called "vintage", we deicided to upgrade, hence the new iMac. (And it was 7 years old after all!!)
    What can I do to get the info I need from the older hard drive? Like I said, it's 7 years old and has a LOT of info. I WAS able to backup pictures, music, and some misc. work to an external hard drive before it died....but I need the "little" things like my address book, calendar, old emails, bookmarks, etc.
    Thanks in advance for any help in this matter!

    If this is an enclosure that is USB powered that may be the problem. Mac are notorious for not putting out enough power from the USB port to properly power these USB powered drives. I suggest you get a SATA to USB Adapter that has it own AC power supply to power the drive.

  • Cable to connect old iMac as second screen for new iMac

    Just bought the new iMac 27" with thunderbolt port.  I understand I can hook up my old iMac (24" Mid 2007) and use it as second monitor.  My challenge is confirming that, and then figuring out which cable to use. 
    The manual says the old iMac has a "Mini-DVI video out port", making it sound like it won't accept input.  True?
    If it will indeed accept input, what cable do I use to connect the two Macs?
    If indeed I can't use the second iMac, I'll purchase a separate monitor.  What should I look for in monitors that will easily attach to the thunderbolt-only new iMac?  I won't be buying the Apple monitor.
    Thanks for any help in advance.
    Bob

    Most new monitors will support standard DVI and VGA connections. Some may support Mini-DVI ports. That's about all I can tell you.
    As for other factors I would look at monitor reviews - as many as you can - for the size and resolutions in which you are interested. There are a lot of products out there. You might try first doing a Google search to learn more about the meanings of the various specs the manufacturers provide so you might wade through the smoke and mirrors in search of meaningful information.

  • Digital Video Recorder with Firewire 400 and new iMac

    I just got a new iMac which has only 1 firewire800 and no firewire 400 ports. My digital video camcorder has a firewire 400 cable to transfer taped recordings to the computer (I want to import using iMovie 09). So, do I simply need to buy a new firewire 800 cable that will plug into my digital camcorder? The reason I'm hesitant is that I've tried using a USB connection, and iMovie 09 didn't open and doesn't recognize that the digital camcorder is connected when I use USB. Does iMovie 09 just no longer recognize my several year old Samsung digital camcorder, or does it just not recognize it with a USB connection, and it will be fine if I get a firewire 800 connection that fits the new iMac? Is there another type of converter--e.g., a cable that allows a firewire 400 to plug in on one end and has the firewire 800 connection on the other end?
    Thanks

    Thanks for the reply. I went ahead and got a new cable and now I can plug for digital video camcorder into my new Mac. Unfortunately, as I feared, the Mac still doesn't recognize the camcorder. I checked the system profiler with the camcorder plugged in, and under Firewire Bus it reads Unknown Device:
    FireWire Bus:
    Maximum Speed: Up to 800 Mb/sec
    Unknown Device:
    Manufacturer: 0xF0
    Model: Unknown
    GUID: 0xF000FFFFFFFF
    Maximum Speed: Up to 400 Mb/sec
    Connection Speed: Up to 400 Mb/sec
    Sub-units:
    Unknown Unit:
    Unit Software Version: 0x10001
    Unit Spec ID: 0xA02D
    Am I just out of luck--the new mac just doesn't recognize my slightly out of date digital video recorder? Or should I be able to get a driver to make it work?

  • "No Boot Disk" on new iMac with external optical drive

    So I am experiencing a problem similar to what some people have had, but I have the brand new iMac which does not come with a cd drive.
    I have a fusion drive in the iMac.
    I downloaded Windows 7 Ultimate from my University software store, which gave me a .img file. I burned this file to disk in order to make the boot drive.
    I am using an amazon basics DVD optical drive which connects to my computer via USB.
    Upon boot into windows, it does not recognize the dvd in the drive as bootable, and says "No Bootable Disk Found, Press Any Key". Of course, I have a bluetooth keyboard and cannot press any key because there are currently no drivers.
    So, any ideas on why it won't recognize my boot dvd?

    It was just a simple case of removing the verbose boot settings which I found a script for after searching on Google.

  • How to transfer my videos podcasts from macbookpro to my new iMac ?

    I've just bought a new iMac and would like to transfer my videos podcast from my MacBookPro without having to download all of them again. I was already successfull in transfering the subscriptions but they are asking to download again all the videos, including the free and the bought ones. That is a waste of time ! Isn't there a Apple smart way to avoid it ?
    Thanks in advance folks !

    You can't do it directly on your iPad. You will need to copy them to your computer : http://support.apple.com/kb/HT4083
    Then add them to your computer's iTunes via File > Add To Library so that they go into the Movies part of your iTunes library, and then sync them to your iPad's Videos app.

  • Whether the screen of new imac(2011mid) exist the dust problem?

    I'm considering purchase the new imac, but afraid of the dust problem of the screen?? So could anybody tell me whether the new imac(2011 mid) exist this problem??

    Hi-
    Please clarify-
    Exactly which version of Microsoft Word do you have installed on your computer?
    Do you by any chance have Parallels or VMware installed on your computer (in other words, are you running Microsoft Windows on your iMac as well?)
    When the screen goes black, does the computer still appear to be functioning? What happens if you do the following when the screen is black: press and HOLD the command key down, and then press and release the tab key once.
    Also, what happens when you just try to start up Microsoft Word normally- not by double clicking an attachment, but by double clicking on Microsoft Word in the finder?

  • How to make a boot disk for new iMac?

    I just purchased a new iMac equipped with a bare bones 1TB SATA hard drive.  I want to replace that disk with a 1TB SSD from Crucial (less than 1/2 of the cost of purchasing the iMac with the SSD).  I have a Time machine backup of the iMac on a Time Machine/Airport device; how do I make a boot disk that can get the OS up and running, and able to restore the backup from the Time Machine?

    Thanks for the quick response...
    TD
    You can take it an AASP to have the install done however you probably would be better off returning the machine (assuming it was bought directly from Apple and is less than 14 days old) and buy the configuration you want. Even if an AASP does install the SSD there is no guarantee Apple will honor the warranty, it's 100% at their discretion.

  • IMovie HD won't boot up on new iMAC Intel machine

    I just bought a new IMac Intel DP and completed the SW updates. Opened iMovie HD and created a new project. The program started to open but gets hung up when loading the "new movie" (which doesn't exist yet) and state loading "saved thumbnails" - this is the first time that I've opened the program. iMovie doesn't get past the loading "new movie" and never fully opens. I've tried reloading the software and rebooting the computer to n avail. Any ideas?

    Well, folks, I trolled further, and found the answer further down on this Forum. The solution below worked for me:

    OK after reading the other post I have the Workaround/Fix
    In my case it was caused by migrating my old account data from my old Mac to my new Intel iMac and using the preinstalled version of iLife 06...specifically iMovie hanging while loading thumbnails with a minute remaining....forever.
    The problem files are in the /User/~yourusername/Library/FontCollections folder. I moved that folder out to the trash and iMovie starts up without a problem. iMovie recreated the FontCollections folder with the files it requires. Hope this helps everyone.

  • Ichat video not working when screen sharing into iMac in target display

    I have my MBP (current model) plugged into my 27" iMac and using it as an external monitor. If I screen share into the running iMac from my MBP, several things aren't working properly. When I try to use iChat video, iChat crashes. Full size images don't show up in iPhoto or Preview. Both of these things do work on the iMac when it is not acting as my display when screen sharing into it. Is there a fix for this? As I would still like to be able to use some functions on my iMac through screen sharing when it is being used as my display for the MBP.

    You are on your MBP. You have the iMac in Target Display Mode. You are using the iMac's display with the MBP with TDM. At the same time you are using Screen Sharing on the MBP to access your iMac.
    Screen Sharing is never a full size view, it is always a window on the Mac's display with a smaller than full size resolution.
    The 27" iMac's iSight is not available to use when the iMac is in Target Display Mode. Neither are its USB or FireWire ports.

  • Best way to clean screen of new imac?

    i got my new mac a few months back and i remember asking at the store what the best way to clean the screen was and was told that the new screens where a special glass that required a special cleaning product, and of course i didn't write it down. i just want to make sure i don't scratch my beautiful new screen...and if i can do it with a fairly affordable product that would be even better.
    thanks in advance,

    I think there is iKlear, but I never tried it, it's pretty expensive.
    Apple themselves say you should use their cloth with a little(!) water (see imac manual).
    I just use the dry apple cloth and from time to time I use a little glass cleaner and a soft cloth. works well for me, others say that alot of glass cleaners are not good for the display, I can't say that's true
