IMAC won't boot with Canon PIXMA MP130 connected

with the printer connected to the machine even with the latest Canon drivers my Imac simply sits idle at the boot stage until I pull the usb connection.Then it continues to boot.If I connect the printer after boot it seem to work fine...what the heck is up ?

It should show (via the times) what service failed to start or sat for ages when the lock up occurred.
Do you hear the normal startup chime when the printer is connected? This would indicate if the POST check has passed.
If you do, then it sounds like the Open Firmware is having the trouble, as it is responsible for initializing the hardware and selecting the OS to use. However, given that you are using Boot Camp, I'm not sure if this changes things slightly.
I would be taking the iMac and the printer in to get checked. By taking the printer, you can try connecting it to another Mac and determine if it is causing the problem.

  • IMAC won't boot with USB card reader attached

    My quite new 24" iMAC won't boot if I have a USB card reader attached:
    I get to the white screen with the apple logo, but it gets stuck there and the little spinning gear below the apple logo never appears (I've waited several minutes). (In all my test cases, there is no card in the card reader.)
    I've tried two different card readers with the same results ("iDOTconnect" brand and a brand new Apacer unit, both are USB2.0 multi-format card readers).
    The 1st one I tried via a USB hub, the second one I tried via a new hub and also directly connected to the mac (both of those hubs work fine).
    Anyone have any ideas?

    Hello strathglass
    The same thing can also happen with other connected devices such as external HD's and iPods, the Startup Manager is lost and searching for a boot volume.
    1. You may be able to fix it by going to: *System Preference / Startup Disk* and select the *Mac OS X 10.5.5 on Macintosh HD* then *Click the lock to prevent further changes.*
    2. Leave those devices that cause boot issues disconnected until the iMac is up and running!
    3. Only sleep the iMac, and be sure to disconnect those devices be for shutting down or updates that require a restart!
    As a habit, I have always ejected and disconnected all mounted USB devices (flash driver, iPods, cameras, card reader, etc.) from my hub be for sleeping, restarting or shutting down...

  • IMac won't boot with external drives attached

    I am using iMac 27" Late 2013 model upgraded to mavericks 10.9.4. Two external drives are always attached with it, one is segate 3.5" 2TB USB 3.0 drive and another one is 2.5" usb 2.0 drive.
    when i start my imac with external drives attached it won't boot up. Stuck at plain white screen after a startup chime, not even any apple logo or any progress circle appears. And i have to detach all of my drives to make it boot.
    This problem arises after upgrading to mavericks. Already tried resetting PRAM, SMC and checked Startup disk and verify disk with disk utility.

    Raja,
    Do a SMC reset perhaps even a couple of times and see if that helps. Also in System Preferences + Startup Disk make sure the internal HD is selected.
    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.

  • Intel imac won't boot with usb powered hub attached

    My intel imac has started to not boot with a powered (have tried a variety of them) attached. Just stops at the white screen. Also, after I attach the hubs (2, both powered) the computer got into spurts when it just kicks everything attached to the hubs off saying that something pulled too much power. At other times it is fine with the same set up. I've tried resetting the PRam but it didn't make any difference.
    I see from other postings that this isn't too uncommon, but didn't see any fix.
    Thanks

    Can you determine if it is just one of the hubs? Resetting the PRAM probably didn't have anything to do with this problem but the SMC controls the power, try this reset:
    SMC RESET
    http://support.apple.com/kb/HT3964
    Shut down the computer.
    Unplug the computer's power cord and ALL peripherals.
    Wait 15 seconds.
    Attach the computers power cable.
    Wait another 5 seconds and press the power button to turn on the computer.
    The 5 second timing is important to a successful reset.

  • IMac won't boot with install CD with gray screen

    A couple of weeks ago I turned on my computer and couldn't get past the gray screen (with no Apple logo). I couldn't boot in safe mode, and had to boot with software install disc. I recently had to unplug my computer for a move and when I turned it on I had the same problem. Unfortunately after resetting PRAM nothing happened, and I couldn't boot in safe mode. Then I tried booting with disc pressing C during startup, and it sounded like the disc was reading ( I could hear it spinning), but I still had nothing but a gray screen. Also tried booting with recovery disc that comes with Apple Protect Plan and couldn't get past gray screen. After I leave the computer on for a couple of hours I get the folder with question mark flashing. Can anyone help?

    den.thed,
    Thanks. I tried the sleep method, but if I were listening to music through my Apple TV or was watching multiple movies, the IMac would shut down or go to sleep after 3 hours and sometimes that became a real bother. I have a HD with just my music from ITunes on it and then I have a new 1 TB HD that I have nothing but movies on it. Those are the 2 I want to leave on at all times, but the machine would freeze if I had both plugged in. Thanks!

  • Imac won't boot with Ipod plugged in.

    60gb 5G Ipod. Imac Intel Core2 duo 2.0 ghz.
    About 80% of the time, if the Ipod is plugged in (through a USB hub), the Mac will only boot to a grey screen. As soon as I unplug the Ipod, the Apple appears on the Imac screen. My Iphone is plugged into the same USB hub at the time, with no similar behavior. I've tried restoring the Ipod with no change.
    I've tried making sure that the startup disk pref pane is set correctly and locked, but for some reason, whenever I check it, its unlocked again. The Ipod does not appear there. I do have a clone of the startup disk attached to an always on external firewire drive.

    Hello Mark
    Having the iPod connected during the boot process is confusing the startup manager!
    First try: *System Preferences / Startup Disk* and select the *Mac OS X, 10.5.4 on Macintosh HD* then *Click the lock to prevent further changes.*
    You can also try ejecting the iPod be for shutting down or only sleeping the iMac when the iPod is charging!
    Normally my iMac sleeps, but as a habit I always eject and disconnect all USB storage devices, iPods, cameras, flash drives, etc. be-for shutting down.

  • IMac won't boot with SATA external firewire drive attached

    I have an 1T Hitachi SATA drive enclosed in a Macally firewire enclosure. If it is attached either in series with other IDE firewire drives or directly, my iMac will boot only to the Apple icon and will not engage the gear icon. If I disconnect the drive the iMac will boot normally with all the other IDE firewire drives attached. I've troubleshot with both Macally and Hitachi, received a replacement enclosure and have an RMA from Hitachi. Before I send the Hitachi back with the possibility of a replacement not fixing the problem, I am asking whether there is a known problem with external SATA drives in particular. TIA. -Dave

    I have the same problem exactly but with two firewire 800 drives attached. Both are LaCie d2 500 gb drives. I have tried each one as the first in the series with no luck. I have not tried to connect with any other type of cable.

  • Imac won't boot with new hard drive installed

    So I installed a new 1Tb caviar black in my PPC G5 Imac, but when I turn the computer on, I get no video, no startup chime, nothing. The power light does come on, and fans start running after a minute or so, but thats it. I can't boot from the install disc.
    The computer boots up as expected when I remove the drive(startup chime, grey screen, missing folder icon).
    Any suggestions to what the problem is? Any help would be greatly appreciated.
    -D

    wierd i have similar problem. I removed HDD after crash to backup in an enclosure before reinstalling os again, put the hdd back and connected the hdd sensor backup (although i thought it was a knock sensor..doh!) . Mac wouldnt start, no screen, no chime, nada, but sleep light stays on. With PCs this usually mean CPU fault so i removed RAM to see if could get a BEEP meaning CPU is ok as it spots ram. No beep. So after checking everything i stripped out ram, hdd, airport and battery and reset PMU, tried again and now i get beep!! so cpu works. slowly adding everything back in and trying power up, last thing to go in was hdd sensor and sure enough when this is connected i reproduce the symptoms. So i disconnected the sensor and tried and i get chimes etc... Ive inspected the cable and made sure is connected right way up and still cant get to work. So it seems sensor is goosed! Debating wether to replace just yet

  • IMac Won't Boot With USB Keyboard Connected

    We have a suite of 10 iMacs (10,1 - 21.5 inch), but one of them will not boot and has issues coming out of sleep while a USB keyboard is plugged in.
    Have tried swapping the keyboard with another iMac - the other iMac still boots but the problem iMac continues to play up.
    Tried plugging the mouse into the iMac's USB instead of the keyboard's.
    Tried SMC reset, PRAM reset.
    Re - imaged the machine from a time machine backup of one of the other iMacs, which made the issue go away for about a month... but then it returned.
    Using a magic keyboard is fine as a workaround, but the users need the number pad, and if possible I'd rather fix the issue than buy a clunky separate keypad.
    Does anyone have any ideas? Any help would be very appreciated!

  • Won't boot with external display connected

    My MacBook Pro (circa 1997) won't boot with the external display connected. I can connect the external display (20in flat planel) after it has started, and it works just fine.
    I have tried two different DVI cables (one of which I think is a DVI-A cable) and the DVI-to-VGA cable. The result is the same.
    During the boot phase I get the tone, the apple logo and the progress wheel. After 30 seconds to one minute those disappear to be replaced by an empty blue screen.

    In case anyone wonders, my "solution" was to change to a WB Elements Desktop 3TB (only USB 2.0 is currently available for this model). I miss the speed of USB 3.0, but it's much nicer to not have to remember to unplug and plug in the hard drive each time I boot.
    Still hoping to see a proper solution to this (since I don't have the WB My Book anymore, I can't test adaher's suggestion).

  • My iMac won't boot past grey screen and it didn't come with a os x disk

    My iMac won't boot past grey screen with apple. I've tried booting in safemode but that didn't help and my iMac didn't come with a os x disk.

    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.”
    b. 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.
    c. 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 either of the techniques in Steps 1b and 1c 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 Fusion Drive or 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 10. 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
    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 10
    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 11
    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 12
    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.

  • My Imac won't boot up. It is stuck on apple logo with spinning gear.

    My Imac won't boot up. It is stuck on apple logo with spinning gear. It will not boot in safe mode, my install disc will not read and fsck wont fix it.. I can hear the hard drive spinning. So i know my drive is not bad.. Right before this happened i was low on space so i deleted a bunch of movies but for some reason i had to change my drive permissions to do so..

    Is your data backed up?  If not, see these means of data recovery: https://discussions.apple.com/docs/DOC-1689 If it is backed up, then purchase Alsoft Disk Warrior.  Boot it using the Option key of a wired Apple keyboard.

    My iMac won't boot up fully. It stays stuck in the gray screen with the pinwheel spinning, then after about 5 minutes just shuts itself off.

    Try SMC Reset (unplug it from the back of the computer for 10 seconds then plug it back. in)
    Try PRAM Reset Cmd + OPtion + P + R on start up.
    Try safe boot - hold down shift on start up.
    Try booting to install dvd (C on start up) or recovery hd (CMD + R) and using disk utility to run a verify and repair. If you still can't boot after that reinstall the operating system. If you can't find the disc or it wont boot to the disc.
    Try single mode which is cmd+S on start up. It will open with a terminal looking window in the terminal. type in /sbin/fsck -TL. If it returns *system has been modified* continue to type that command in until it comes back with macintosh hd seems to be ok. If after 5 tries it still gives you system has been modified. You may have to replace the hard drive.
