New iMac crashes, start up problems, flicker screen...

Purchased iMac four months ago. It seems to be a bit flaky – as a life-long and loyal user of Apple, not what I was expecting! Often have problems crashing or hard disc error messages at start up. Flickering screen.
Also not sure that I got everything that I requested at the store – I had asked for an additional back up drive in store when ordered and I've looked on my iMac and it doesn't seem to have this. Currently backing up to iCloud and on DVDs to make sure I don't lose anything if my computer gives up the ghost and dies!
Bit disappointed really. Never had problems with any Apple products before and saved up for quite a while to upgrade my very old G4 (which still runs like a dream, and only updated because it's operating system became incompatible with latest software updates) to a new iMac (which seems a bit buggy).
Asked around and a few people have found iMac to be less reliable than previous Apple computers. Anyone else have problems with iMac seeming less stable?

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.
You'll have to take up the missing backup drive with the sellers. The iMac doesn't come with one.

  • New iMac crashes permanently - bluetooth problem?

    Hi all,
    my new iMac (27-inch, Late 2013) is constantly crashing, especially after the execution of a particular gesture on the Magic Trackpad. The crash after moving the scroll wheel on a wired Apple mouse has so far occurred only once. After the phone call with the Apple support I have deleted and reinstalled the system and then copied the data from an old system from a Time Machine backup, and reinstalled my programs.
    Unfortunately, the problems are still there. These are the results of EtreCheck:

    Thanks for your thoughts.
    I have not restored my system via Time Machine, but after reinstalling I just copied my documents and small programs on the new computer (no preference files or something like that).
    The memory was installed by my reseller (four 8 GB modules from Kingston).

  • New iMac is stuck on grey apple screen after restart from Migration Assistant

    New iMac is stuck on grey apple screen after startup. It is a 3.4GHz Quad-core Intel Core i5 running OS 10.9.4. The problem occurred after a migration from my older 2009 iMac which is running Snow Leopard 10.6.6. When the restart occurred from Migration Assistant, the new computer will not boot up to the login screen. Disk utility did not solve problem. Followed instructions for a soft reinstall of Mavericks but that also did not solve problem. Any suggestions?

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    Step 1
    The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
    There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
    a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
    b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
    c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
    Step 3
    Sometimes a startup failure can be resolved by resetting the NVRAM.
    Step 4
    If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
    Step 5
    If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
    Step 6
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    Step 7
    If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
    Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
    If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
    If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 8
    Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
    Step 9
    If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.  
    Step 10
    Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 11
    Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
    Step 12
    This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
    Step 13
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

    Some times my new iMacs display start flickring when I starts playing a game. I am very annoyed. I have bought it only 1 month ago. What can I do?

    A flickering display sounds to me like a hardware problem.  Or does this only happen with a specific game? Of course your machine is still under warrantee so you could take advantge of it if you have a local apple store.

  • Start UP problems, blue screen, Imac (intel) 1.83  17"

    I posted this Saturday in a different area. So forgive me if I did this incorrectly.
    Imac DuoCore 1.83 (originall with 10.4 Tiger)
    Upgraded to Leopard several months ago without problems.
    Have the lastest updates.
    Two days ago the following started:
    1. Starts up-no chime
    2. Apple logo is seen (grey)
    3. light blue screen with progress wheel-not the pinwheel)
    4. screen dims a bit, progress wheel dissappears then comes back and it does
    the same thing.
    I ran the Disk First Aide from the CD, performed verify and repair disc.
    Came back with repaired completed. Everything seemed ok.
    Restarted...but the problem persisted.
    Next I reset the PRAM...
    Chime came back on start up.
    Ran the CD a few again. Said it was all ok.
    Restarted....and back to blue
    I ran hardware test from the original CD
    all came back fine. Two items were repaired.
    Restarted and back to the blue screen.
    Tried Single user interface and ran /sbin/fsck -fy
    Again 2 items were found and repaired.
    Restarted.
    Hardware and software seems to be fine acccording to this.
    SO it seems it's the PRAM battery. I think. ANy other ideaS???
    ALSO...this machine is out of warranty. Not afraid of cracking it open.
    But, where is the praam batter located? Like to know what the part number is to have it on hand when I open it.
    Any help appreciated.
    RLM

    I opened up my iMac and replaced the PRAM battery. No change.
    I then took out the Hard drive and placed it in my G5 destop.
    When i restarted it I could see the hardrive and it's contents. Both HD have
    10.5.7 installed so I thought I could restart with the Imac HD
    and then back it up. But it wouldn't start up and jumped to the
    G5's HD. My question is:
    1. Is the reason it would not recognize the iMac HD as a start up disk because
    it's from a duo core intel mac?
    2.Is it because the iMacs HD has some problems in booting up?
    (as I wrote before I have run every test available with positive results
    yet continue getting the blue screen)
    And since I can read and see the imac drive in my G5, how can I back it up short of dragging everything to a new drive since I can't log into the individual users. Of primary importance are the pictures in iphoto in different user accounts.
    Thanks for any help

  • New iMac crashing after Lion and SN updates

    Well this is my story bought my new imac Jan 2011 - Snow leopard 10.6.4 installed - worked fine problems started after upgrades to 10.6.5 and 10.6.6 - wifi probs initially then a tendency to crash to black screen about twice a day - just a little click noise then nothing often when surfing.... anyway endured this prob and thought upgrading to Lion might fix it...
    After installing Lion my new imac ran for 2 mins max before crashing to black screen - I went online and tried all 'known' fixes (no help) - I am now back to 10.6.4 and have had a trouble free day ....been using macs since 1993 and never recall a prob as bad as this - still have a Blueberry imac running OSX beta (lol changed the clock) and Emac running 10.2

    Also as a general rule of thumb NEVER NEVER EVER EVER  upgrade a computer that isn't 100% stable at the time of the upgrade. When you do you are NOT fixing a problem you are making the problem much more difficult to troubleshoot and fix. You may benefit by reading Understanding upgrade nightmares, this should help explain and possibly shed some light on your problems. My iMac has successfully upgraded over many many updates including major OS X upgrades from Tiger to Leopard to Snow Leopard and now Lion. In each case the migration was simple and the computer remains as reliable as it did when it was new. This is primarily because the computer was stable on each upgrade.
    My recommendation would be to start all over again with the base version of OS X that was installed on your system. Do an erase and install and only upgrade to the next version of OS X when the system is 100% stable. WZZ wrote a good guide on the process he does when he upgrades, I do something very similar and as explained each update has been very smooth. Please read his Update Process.

  • Brand new iMac 27" i3 is flashing blue screen

    My brand new Imac (one-day old) is acting very odd as it slowly flashes a pulsating light blue screen when I try to access Apple Menu (restart/sleep/shutdown) features. No matter what I do it will not turn off. I have since had to do a hard shutdown but now it stops at an error screen upon start-up that tells me to restart!
    I am Mac savvy and this has never happened to me. Prior to this happening, I called Apple Tech Support because I could not use their Mac Migration feature to move my info off of a G4 running 10.4.11. Tech support could not help either as wireless, ethernet and direct Firewire attempts yielded no Migration results. I finally had to pull the hard drive out of the G4 and hooked it up to the new iMac. Everything seemed to transfer except when it was done the contents of what I just copied thru Migration was nowhere to be found. That is when I started experiencing the slow-flash blue screen phenom and is where I am stuck today.
    I am ready to take this thing back. In all my years I have never had a problem like this with an Apple product. Any help or insight will be appreciated.

    ONE
    Paul has given you good advice in that I would reinstall the OS from the supplied disks to get your computer working properly.
    TWO
    Then re-install your old programs (only those you really need since they are likely PowerPC, not “universal” Intel programs) from their original disks.
    THREE
    If you have the user data from the old drive backed up, then hopefully you can restore your user data to the new drive or buy an enclosure and access the old data as needed (which is what I did when originally migrating from a Power Mac G5 to the iMac (late 2009).
    Alternatively, if step ONE is problematic and your machine is defective, you can likely return it to Apple within 14 days (or whatever the law is in your country) for a replacement or refund and purchase a new iMac just released today.  Steps TWO and THREE still apply in this case.

  • New iMac freezing, showing Graphics problems and Wifi Problems on 1st Day

    My sister just received her new iMac - 20 inch - 500 GB drive.
    I started seeing problems during the download of the FIRST software update from apple. There was a black box in the lower left corner of the software update window where it should have been grey (or metal).
    On reboot, I also occasionally show weird flickering graphics in the lower right of the login screen.
    My new iMac also frooze about 4 different times during the installtion of various updates during the first 4 hours of use. Mouse and keyboard would not work. Once it frooze at the login screen after clicking on the user name.
    I also had wifi issues. After three hours of use, my STRONG wifi connection was lost. Moreover, I could not see any other wifi stations. (normally I would see 5 other wifi access points from my sister's neighbours). After reboot, the other wifi access points would appear including my sisters but I could NOT connect to my sister's wifi access point. It said I had an error. I checked the keychain and it showed the right key/password for my sister's wifi AP. I had to run Mac Network Diagnostics and reset wifi to get things working again.
    It sounds like a sick iMac. I know others have experienced freezing. But given all these problems, should I ask for a new imac?
    Rob
    P.S. My sister got AppleCare as well. Maybe that was a good thing...

    I had a long chat with Apple Support. It would appear that Apple's policy is not replace the computer unless it can be determined that it is a hardware problem (even though my problems started to appear right out of the box before I even had a chance to download any updates). According to the Apple product specialist, sometimes there are bad installs of the OS at the factory.
    Apple wanted me to format the drive and reinstall the OS.
    Fortunately, I did not have to reinstall the OS! I started to see graphics problems when I was asked to run the Disk Utilility off the Install DVD (so I could format the drive). So clearly there was a hardware problem.
    In retrospect, I really wish there was an Apple Store nearby to buy Apple computers. I am sure the store manager would not ask me to go home and reinstall the OS etc and try again when the computer doesn't work properly out of the box.
    Those who have Apple Stores nearby do not know how lucky they are!

  • IMac 24' starts up with Pixelated screen and hangs.

    Lately ive been facing problems with my iMac (2009 early model, 3.06 Ghz Intel Core 2 Duo, 4Gb DDR3 RAM). Mostly its during start up. iMac has pixelated screen and the loading wheel also hangs and sometimes the screen also starts blinking. I need to long hold the startup button at the back to reboot, which sometimes works in one reboot and sometimes it takes 3,4 or may be more. Also after starting up, the pop up shows, that computer was not shut down properly. After starting up, iMac has started freexing and pixels start appearing and screen freezes (scheck creenshot below), but I've noticed that even after freezing, I've had the internet on my phone working perfectly fine, which runs via the iMac's wifi sharing.
    Can someone please help me solve this issue. The motherboard has been recently replaced due to other problems i was having. What could be causing the start problems ? IS my hard drive crashing or what?
    Plese help.

    That looks more like a problem with the GPU. You should run the Apple Hardware Test http://support.apple.com/kb/PH11342

  • New iMac Can't See HD and screen goes black then grey then black..etc.

    Hi I've got a new 20" Alu iMac and it was working fine for the past 3 weeks. All of a sudden this morning starting it up the screen went completely grey then after a while the apple logo came on (I thought it was eventually starting) then it went completely black (this is normal just before the progress bar jumps in) but this time it didn't! , the screen just went to grey again and the cycle started again and kept going on like this for an hour. I tried starting up from the disk the iMac came with but under disk repair i could not see the HD and trying to reformat the HD it was just named 'Media'. When selecting the drive to format an error came up saying explain it could not be formatted in the selected format!!! There is only 2 options to format the drive.. Mac OS Standard and Unix.. Both did not work. Any suggestions? Thanks

    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. It's not clear if that applies under the 90-day warranty.

  • New iMac crash

    I got a new imac last week, 2.8 GHz Intel Core i7 with 8 GB of memory. Itunes crashed it the other day and today Safari crashed. I needed to restart to get back on line. I don't know what to do. How do I find the problem. Should I return it, did I get a bad one ( I know that sounds stupid ) or are all macs like this. I didn't spend this much to have dumb problems.

    Hi and Welcome to Apple Discussions...
    should I return it, did I get a bad one ( I know that sounds stupid ) or are all macs like this. I didn't spend this much to have dumb problems.
    Some trouble shooting might do the job. Applications crash for a reason.
    For Safari... go here for trouble shooting 3rd party plugins or input managers which might be causing the problem. Safari: Add-ons may cause Safari to unexpectedly quit or have performance issues
    When an application crashes you will be prompted to save a crash log.
    The next time Safari quits unexpectedly, you will be prompted to save a crash report. Select "report" on the quit panel. The Crash Report will shortly appear. *Copy/paste the entire crash report to your reply here.* If you have problems doing it that way then try this...
    How to locate a crash log:
    Open Finder.
    Click "Go" in the menu, then select "Go to Folder".
    Copy and paste this path into the Finder dialog:
~/Library/Logs/CrashReporter/
    Click the Go button.
    Finder opens the folder containing the crash log. Look for a the crash file with a date field that looks like the *most recent* and copy/paste in your reply here.
    Since you are running Snow Leopard, *make sure Safari is opening in 32-bit mode, not 64.* Right or control click the Safari icon in the Applications folder, then click: Get Info In the Get Info window click the black disclosure triangle next to General so it faces down. Select 32 bit mode. Also, (in that same window) make sure Safari is NOT running in Rosetta.
    As for iTunes, please post in the iTunes Forum for help.

  • Video converters from app store and online making my brand new iMac crash continuously, why?

    I have downloaded various video converters from the app store and online and it seems that no matter which one I use they all make my brand new iMac (I've had it less than 2 weeks) crash. I've wiped the disk once and reinstalled mountain lion twice as directed when I rang apple and I'm still encountering the same problem.
    I would really like to find a way to fix this problem without having my mac sent away for repairs.
    Has anyone else encountered this problem or know how I could fix it?

  • Start up problems and screen shake

    Dear all
    I have started experiencing problems when I start up my iMac. Prior to the Blue Apple Screen appearing on startup I get a fuzzy grey screen with thin lines moving up and down the screen. This lasts for about 5 seconds then clears when the Blue Apple screen comes on. It never used to do this.
    Once I am logged in my screen tends to have a series of small dots (like pixels) forming short lines across the screen. These change each time I log on.
    Also, when this has happened the whole screen goes 'fuzzy' for a few seconds before clearing again. This can re-occur at any moment.
    This problem does not always happen but maybe three out of four start ups. If the problem at start up does not occur then I do not experience the fuzzy screen.
    Any ideas? I am very concerned that something critical is up.
    I have done the most recent updates.
    ps I am not a computer whiz!
    Regards
    Adam

    Hi Adam,
    This is exactly what is happening to my iMac which will be repaired this week. It is critical but it is due to a known fault on some of the iMacs.
    Go to http://www.apple.com/support/imac/repairextensionprogram/
    Even if your iMac is out of the 1 year warrenty it will be covered for this.
