Brand new iMac has hundreds of vertical lines on screen...?

I know from flipping thru the archives this is a common issue, but usually on older models - I just purchased and turned on my iMac for the first time today, and it worked fine for a couple hours before randomly acquiring a complete screenful of flickering, multicolored, vertical lines. I'm performing a hardware test as we speak (I'm posting from my four year old iBook, which ironically still works) but pending those results, what can I do? Am I going to have to exchange this brand new computer for a NEW new one?

I bought mine last week and it works flawlessly. If I were you I would not bother with any diagnostic tests and just return it to the store and get a brand new NEW iMac since you just purchased it today. If you bought it online then there's little bit more hassle that you have to go through but even if you can get the problem all fixed by yourself, I would just return it to apple. Good luck.

  • I have just bought a brand new iMac plugged it in and nothing, black screen any suggestion, not a great start to my first mac experience

    I just bought a new iMac, plugged it in and nothing, black screen any suggestions and the apple support function is no help, real glad I bought the apple care plan and you can only use that if your machine turns on!

    If you bought the computer at an Apple Store return it. Let them know you aren't happy about your start in the Mac world. If you bought the computer online and have an Apple Store nearby you can take it there even though you didn't buy it there. Note: if going to an Apple store go online and make an appt with the Genius. Stores tend to be busy so this will give you a time to know you can walk in and pretty quickly get attention. Just walking in with a dead computer you may have to wait a while.
    No Apple store nearby? No problem, call AppleCare and they'll take care of you. Ask for expedited return & shipment and again, let the technician know you are new to the Apple world and not happy. The last time I brought home a dead computer I not only got a replacement right away but I got an Apple gift card for my inconvenience.

  • I just updated my brand new iMac and now I get a white screen

    I just updated my new iMac and all I get is a white screen.  It went from installing to the white screen.  I can do nothing but shut it down by pressing the on/off button.  When turned back on I get the white screen again.  What happened?  What can I do about it?

    If the system is less than 14 days old, you said it was "Brand New", take it back and get a refund and then buy another. Apple has a 14 day No questions asked return policy for full refund. Take advantage of and get a system that works correctly. The one you have certainly isn't.

  • My brand new iMac won't start up now and I've only had it 3 weeks...

    my brand new iMac has worked for 3 weeks, then all of the sudden won't start. It shows the apple icon and the spinning wheel but never gets past that screen. We already formatted our old iMac to sell it so I really need to recover this. Any ideas on how to get it to get past this screen? I already tried safe mode but it went to this apple logo and spinning wheel icon after the bar

    2nd.  This is a warranty issue.
    You realize this is a forum of other comsumers right?

  • My dad has a brand new iMac. If he quits an app, this window closes, but the app won't finish shutting down, Force quitting does not work.  Once another app is opened, it will not close either.  Now none of the apps are responding. Any ideas?

    My dad has a brand new iMac. If he quits an app, this window closes, but the app won't finish shutting down, Force quitting does not work.  Once another app is opened, it will not close either.  Now none of the apps on the dock are responding. I asked him to click on the apple, and drop down to "About this Mac", but that wouldn't open either. Any ideas?  If I was at his house, I would call Apple Care in a heartbeat, but am home with my sick daughter,,,  Thanks!

    For starters, have him open Disk Utility in Applications>Utilities, select the volume (the indented listing) and Verify Disk. If it reports any problems, have him try a Safe Boot by holding the Shift key at startup. This boot will take much longer than usual. It's checking and trying to repair the drive directory, if possible. Once in Safe Boot, have him repair Permissions.
    For other Disk repair remedies see
    http://support.apple.com/kb/TS1417
    Also, have him try a PRAM Reset. At the startup chime, hold down CMD-Option-P-R together, listen for two more chimes, total three, then let go to finish booting.
    Also, is he running any AV? If so, have him uninstall it. It might be responsible for this behavior. (There are no viruses for OS X.)

  • Brand new iMac 27 has no sound

    A buddy just got a brand new iMac 27, out the box last night. It has no sound.
    He went to Systems Preferences and the Sound page provides no solution. Nothing can be clicked.
    I know the solution is probably insanely simple, but cannot figure it out.
    Help please.

    The simple solution is take it back to Apple and ask them to fix it.

  • Hi, I have a brand new imac which i got today and when I open Iphoto all i get is the error message "Your photo library is either in use by another application or has become unreadable" any ideas? thanks

    Hi, I have a brand new imac which i got today and when I open Iphoto all i get is the error message "Your photo library is either in use by another application or has become unreadable" any ideas? thanks

    Are there photos in the Library? If not then just trash it and launch iphoto. It will make a new one.
    If there are pics in it then Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
    Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

  • Vmware fusion 5.0.2 cannot connect to network on my brand new iMac '27 late 2012

    Dear friends,
    I have tried to install Windows 8 (x64bit) Pro., Windows XP, and CentOS 6.0 using vmware fusion 5.0.2 over my brand new iMac '27 late 2012. However, neither one can connect to the Internet. There was no problem with the same installation on my iMac 2011.
    The network board recognized by Windows 8 is Intel(R) 82574L Gigabit Network Connection.
    In the folder of vmware fusion's setting files on Mac OS, I found a file called Windows 8 x64.vmx, and
    there is a line as follows.
    ethernet0.virtualDev ="e1000e"
    Any friend has the same problem or can give me some hints?
    Thanks a lot!

  • Brand new iMac does not work wirelessly

    This is a very strange situation and I don't know how much to be concerned about it.
    6 weeks ago I bought the first of two brand new iMacs. We have two old G4s both wired into a Netgear wireless router, plus the printer. The first new iMac when switched on, immediately found the Netgear and has worked perfectly, wirelessly, ever since. As it should.
    Less than a week ago I bought the second new iMac, which is identical to the first. I put it on the _same desk_ as the Netgear, therefore a distance of only one foot. Straight out of the box, it worked wirelessly to register itself with Apple.
    Since then, it has only worked wirelessly very intermittently, and then very slowly indeed. I was wasting far too much time trying to figure out why the wireless did not work, and eventually wired it into the router too.
    I was attempting to set up a network with 2 old G4s wired in, and 2 new iMacs wireless. Now I have 3 wired in and one wireless.
    Is there something wrong with the second brand new iMac? Or is there some line I should be pursuing with Netgear?
    I have written all the IP addresses down in case anyone responding - and I sure hope SOMEONE responds! - thinks that this may be a clue.
    Many thanks in advance to all and any replies.

    Update: I'm posting this in case it helps others......
    I phoned the software support which comes free for 90 days with a brand new iMac.
    The bright young man there instantly knew what the problem was, because he'd seen it all before. There's nothing wrong with the iMac and it has nothing to do with IP addresses.
    I have to go into the Netgear configuration screen and Enable MAC filtering. This means I'll give the router the hardware addresses of the two iMacs and it will then allow both of them to communicate wirelessly - but no other devices which might be lurking in the vicinity.
    Sounds good to me.

    Photoshop CS6 keeps crashing. I am using a brand new IMAC, I have 16GB RAM recently updated as it was running slow with 8GB and lots of hardrive space. When it crashes, i lose all my presents and it changes my preferences, it also fails to save or produce a recovered file despite settings asking it to do so every 5 mins now. When i try to report the problem, it says it has found an issue and gives me a link to a solution....but wont let me click on the link.... PLEASE HELP! It's killing my productivity.

    If the crash started right after you added RAM, it could be a bad Ram dimm. You can try this - change the amount of RAM in Photoshop to 4G, this should stop Photoshop from using the higher ram. If it doesn't crash, it's probably the ram. Or run a diagnostic app. You don't say when it crashes, what you're doing when it crashes - it there a pattern? Did it ever work on this computer? Did it work on your previous computer? Without a lot of data, it could be related to the new computer... What OS version? Did you recently update it? Have you updated Photoshop to the most recent update?
    Do you have any plug-ins loaded? Try restarting Photoshop, and immediately press & hold the shfit key to turn off plug-ins.

  • Brand new iMacs with Lion will not read DVD-R

    Our business has just purchased 3 x brand new iMacs (3.4Ghz) pre-loaded with OSX Lion 10.7.2 and NONE of them will read a DVD-R containing important files I need to access. However, the trusty 2 year old iMac running Snow leopard sees the files instantly....what's wrong with Lion...?
    My 2 year old MacBook pro was updated with Lion a few months ago and hey, it stopped reading DVD-R's....how interesting....! It can't be ALL of the superdrives failing, so it's obviously a fault with the OS...seems to be a VERY common problem, so what's the problem in getting it fixed?

    Contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine.

  • Slow performance, brand new iMac!

    Hello!
    First, excuse my rusty English.. I hope you manage to read it
    Main problem.. Adobe, PhaseOne and other intensive applications is veeeery slow on a high specced brand new iMac! Lightroom 5, PS CC and Capture One Pro 7 is what I use mostly.
    I just got my brand new iMac 2014.2 (3.5/3.9 GHz, 32 GB RAM, 512GB flash disk and GTX780M), and its quite a lot slower than my other Win7 workstation. Other workstation specs: i7 4.2 GHz, 16GB RAM, 128GB SSD, GTX 580. I'm working on the same Raid-5 drive (USB-3) too, so I don't know why it's slower..
    What I experience:
    Changing from "current" raw to next raw (while culling) takes several seconds, and my Raid-5 is done chewing long before I see the result on my monitor. I get the spinning beach ball while waiting for preview. I always render 1:1 on import and 1:1+standard size in menu, just to be sure. Adjustment brush is like dodging in PS v1.0 (NOT CS) when computers had less disk-space than we have cpu-cache today, awfully slow, and it "stutters". Moving/panning in 1:1 is very choppy, and sometimes I get the spinning beach ball while panning.. This happens in LR and CO.. Photoshop CC stutters or have to "think" when I try panning. These problems happens in 6 Mpix, 12 Mpix or 25 Mpix RAW files, and actually in some JPEGs too!
    I have done following:
    I've tried 2003 and 2010 processing in LR, small change. Fixed permissions in OS X. Removed preferences for LR, CO and PS CC. Reinstalled LR/cloud apps and Capture One Pro 7. Increased camera raw cache from 15 to 50 GB. Followed Adobe's guide to make LR faster. Followed Capture One guides. Reinstalled (clean install) of OS X. I've tried all tips I could find in the forums around.. I have also tried placing RAW files on internal 512 GB disk to see if that helps on performance, but no change. Same story with camera raw cache, doesn't matter where it is.
    Additional things.. I’ve also diagnosed the iMac with checkdisk, memcheck, logs, etc.. No problems as far as I can see.
    I just changed my workflow from Win to OS X and I depend on this to work.. I currently have 4000 files from my last job waiting to be worked on, and I'm not finished until Christmas in this tempo :-(
    If I can't get this working very soon, then I have to return this very expensive iMac and buy a new PC again..

  • I have a brand new iMac that does not have iDVD. Made a move on iMovie installed a 3rd party burn prog. but DVD won't playback on my regular dvd player. Need to burn one that will. Help!

    My new iMac did not come with iDVD as they are not using iDVD any longer.  I made a movie that I needed to put on a DVD that would play on any external DVD player. After calling Apple twice, they recommened a 3rd party program so I downloaded "Burn-osx" and made the DVD; however when i insert it into my player connected to the TV it gives the message "disk error --playback feature may not be available on this disk".  Ok--now what?  I am up against a time line here--need the DVD for a graduation party! Help! What am I not doing correctly?

    I have a brand new iMac
    If you are still within your 15 day return period.  Call Apple they will sent out iDVD at no charge.  (There are no realistic substitutes.)
    Nicely explain that you may return the computer without iDVD. That usually does the trick.  You MUST speak to a senior advisor to get a free copy. The first tier people cannot do it.
    408-996-1010
    800-692-7753
    If that doesn't work you can purchase iLife 11  (includes iDVD) on disk.
    IDVD is a wonderful piece of software and well worth the low cost of $40.

    they recommened a 3rd party program so I downloaded "Burn-osx"
    Yes, there are programs that will put a movie on a DVD.   I have tried most of the other substitutes including Toast, Burn, and others.  None of them come anywhere near the ease-of-use and power of iDVD. IDVD is specifically designed to work with iMovie. Get iDVD.
