Imac crashes can't restart it

imac starts, shows the apple icon, a bar that starts moving then shuts back off and it will do the same when I turn it back on again

Try an SMC reset:
SMC Reset
Shut down the computer.
Unplug the computer’s power cord and disconnect 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.
and if that works you might want to do a PRAM reset:
Reset PRAM
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.

  • Finder Crashing, Can Not Restart, The World is Blowing Up

    I'm at a loss here. My computer, even after a clean install is simply not behaving well. For example:
    1. I can't restart the computer. When I choose restart, the dock and menu bar go away and then I get stuck at the desktop picture. The spinning lines just spin and spin and spin and it won't restart.
    2. I can't shut down the computer, the exact same thing happens.
    3. Every time I start up, Spotlight has to index every drive connected to my computer. Every time.
    4. Finder crashes about once a day and crashes so hard sometimes that I have to hard restart.
    5. Most applications are completely unstable and crash often.
    The steps I've taken to remedy the situation:
    1. Reinstalled the full 10.5.1 updater
    2. Zapped the PRAM
    3. Booted from the Leopard disk and repaired permissions
    4. Single-user mode to run fsck
    5. Disconnected everything but my keyboard and mouse and I still couldn't restart
    6. Removed any applications that might not be playing well with Leopard (i.e. not specifically noted that it works with Leopard)
    I'm using the in-the-box keyboard and mouse for my iMac. I've never added any after-market things to my iMac like a new hard drive or RAM. Everything in the machine is the stuff that came with the machine. I do have a 500GB FW400 and a 2TB FW800 hooked up. I also have an HP printer, Sony Cyber-shot, iPhone dock, and USB hub connected to my iMac.
    Are there any tests I can run that might help me identify the problem? I'm not looking forward to lugging this to an Apple Store only to have it taken away for a couple of weeks while they try and figure out what's wrong.

    Hi
    You could try reinstalling a clean OS and not preserve network users and settings. Repair the disk beforehand. If your mac is stable the whole time the installer is doing this odds are its not your mac that is the problem.
    However assuming you may have a hardware fault
    Switch your mac off and turn it up on its end, use a cross-head screwdriver to remove the one retaining screw that allows you access to the RAM slots, touch something metallic to ground yourself and remove both sticks of RAM. Now place the mac right way up insert the power cord and depress the power on button. You should see the boot light flash regularly as well as hearing a single monotone beep. Depress the power on button again to power off the mac, remove the power cord, turn the mac over and re-insert one of the RAM modules in the rightmost slot. Make sure it is seated correctly and in place. Be firm when installing RAM but don't be too rough. Turn the mac rightway round again, insert the power cable and see if it boots normally. If still no joy repeat the instructions until you have tried both RAM modules singularly in each RAM slot. If at the end of all this your mac is still playing up, take it to your nearest Apple Authorized Repair Specialist.
    Hope this helps, Tony

    That panic was not caused by third-party software. If it's a recurring problem, the remaining possibilities are (1) a damaged Mac OS installation; (2) a hardware fault, which could be internal or in a wired peripheral device; and (3) an obscure bug in the Mac OS.
    You can rule out the first possibility by reinstalling the Mac OS. Probably there will be no change. In that case, make a "Genius" appointment at an Apple Store to have the machine tested.
    Print the first page of the panic report and bring it with you.
    Back up all data on the internal drive(s) before you hand over your computer to anyone. If privacy is a concern, erase the data partition(s) with the option to write zeros (do this only if you know how to restore, and you have at least two independent backups.) Don’t erase the Lion recovery partition, if present.

  • Media Upgrade Crashed - Can't Restart

    I recently upgrade to FCPX 10.1.1.  When I started FCPX I got a message about needing to upgrade my files - I clicked OK and sat back - then FCPX gave an error message part way through the media upgrade - I didn't look too closely at the error - but it stopped the upgrade part way through.  It asked if I wanted to move the old files to trash, I said no, and exited FCPX with the intention of starting again - but I don't seem to be able to.
    I've got rid of the new library file and put the events and projects folders back where there were, but FCPX just creates a new empty library and doesn't offer to upgrade media.
    I've done some digging and found a reference to using Event Manager X (which I have) to organise media into separate libraries - this seemed like a good idea (given that FCPX crashed on upgrading one of my events or projects) - but I had the same problem - I can use EMX to hide all or most of my projects and events, but the new FCPX ignores everything - whether there's anything unhidden or not.
    So I see two ways forward:
    how can I get FCPX back to it thinking it is running for the first time (to try and get it to pick up my media in the old file structure again)
    is there a way of simply importing into a new FCPX library the events and projects folders from the previous version?
    Or if those are both daft approaches - any better ideas please?

  • I can't install Xcode - My iMac crashes

    Until a few months ago, I had an old version of Xcode (I'm sorry, but I don't remember the version) that I downloaded from the Mac App Store. What I downloaded was like an installer for Xcode, rather than Xcode itself. When Mountain Lion came out, I tried to update to the new version of Xocde (now it was the actual Xcode that downloaded) and it downloaded as usual, but when installing, it made my iMac crash. I tried many times, making my computer crash every time, until it finally installed succesfully (honestly, I don't remember if I did something in order to install it succesfully… I think I deleted the older version, I'm not sure). After that, it worked fine and I thought the problem was solved. I had no problem whatsoever installing it in my new MacBook Air.
    Today, Apple released a new update for Xcode. And the same thing as before, when it begins the installation, my iMac freezes for a second and then restarts itself. After the restart, Xcode appears "In Pause" or something like that in Launchpad. If I try to open it, I can downloading it again, but when it finishes downloading and begins the installation, it fails as I've described.
    What could be the cause of this? And, of course, what can I do in order to fix it? A permanent fix, preferably.
    Thank you.

    Same happening to me. I cannot complete Xcode installation because of a crash.
    I cannot even run old Xcode, I get an alert about the program being upgraded.
    I did a try to the direct installation via .dmg, but it ends up the same.

  • Ever since installing MacKeeper on my IMac I can no longer watch videos on YouTube, they stop in mid sentence and cannot be restarted!  Could this be a problem with my Snow Leopard

    Ever since installing MacKeeper on my IMac I can no longer watch my subscribed to videos on YouTube!  They start very slowly and then stop mid-sentence and cannot be restarted!  I am wondering if it is time to change to Maverick or try to get rid of MacKeeper.  I purchased it because my email had been hacked and now I am wondering if it was a very unwise decision since experiencing these problems?
    Is there anything that can be done to unstick the YOU TUBE videos?

    Mackeeper is the worst pile of crap you can install. A search of these forums will tell you the same thing over and over.

    Both Memory Clean and Clean My Mac could have cause the damage which triggered the kp.
    I would back up your Mac, erase and reinstall. Then Migrate your user data from the backup.
    Uninstalling Tuxera is a troubleshooting process. You don't have to keep it uinstalled, just long enough to test to see if it is causing the problems.
    However, if it doesn't happen regularly, it would be hard to determine if it was the cause.  And, as I mentioned, I don't think it would be the cause.

    The RAM has either gone bad or somehow become unseated. Also there is the chance that the RAM slots have failed.

  • ALERT - iMac Stock in safe Boot. Can't restart!!!

    iMac 27 inch, Mid 2010 on Mac OS Mountain Lion
    I did a safe boot restart and the iMac crash after I see the Apple icon on the grey screen.
    Is there a way to restart in normal mode?
    I tried many things, it is stuck in safe boot mode.
    Thank you

    Have you tried a PRAM reset?
    Shut down your Mac.
    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 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.
    Do you another wired keyboard you could use to see whether the existing keyboard has developed a problem.

  • Why can't restart my iMac after I updated OS SOftware

    Can't restart after I updated the software.....

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
    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 a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
    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 in OS X 10.9 or earlier, 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.

  • IMac Crashing; No Fixes Working/Getting a Chance to Work

    Hi, this is my first time on these forums asking a question, so forgive me if I've categorised this wrong or something.
    I use my iMac nearly everyday for browsing the Internet, word prossessing, digital drawing and playing Minecraft. So, personally, I don't think it is ever being put to degree of stress because I've been doing those same tasks on it for well over a year and it has run smoothly and given me no trouble. However, two days ago, I logged in and got a finder error message, which although I found odd, I simply okayed, not really taking a note of it as I in no way expected  crashing issues to arise from it. The error code started with something like -108, which I now believe was the code -10810.
    So I continued using the computer after I okayed the message, only to find that Skype (which automatically opens at login) quit unexpectedly. After clicking the "reopen" button on the report,  the Skype icon bounced once, the blue light underneath appearing for a second. After this I noticed the finder report and clicked it's "reopen" button and thought it didn't work as the report was still there, but it was in fact a second report as every time I tired to open finder, I would receive a new report in mere mili-seconds. I tried other programs such as Safari and Minecraft and they all wouldn't open. Then I went to restart the computer when I noticed the Apple icon and toolbar missing. So I shut down the computer using the power button.
    On reboot, things started going crazy. Booting took a while, when it loaded the desktop, it would fade to blue for a few seconds then fade back to the desktop. After a few minutes, the dark, transparent curtain moved down the screen and the message "You have to restart your computer" appeared.
    I've tried numerous times to find out the problem/fix it but nothing seems to be working. Worse, the computer either crashes/freezes at login, crashes within seconds of reaching the desktop or works fine (with noticable odd things occurring [such as the screen going blue, desktop items disappearing and then reappearing] but if I try to run things that may help fix my problems (such as software update, reinstalling OS X) the computer crashes/freezes.
    What I've tired so far:
    The reset (I can't remember the name) where you detach the power cable and hold down the power button for five seconds, then reattach the cable and turn on the computer. No apparent effect.
    Safe Mode:
    Worked first time, however it crashed while on the desktop on second and third use, after which I haven't used it.
    Single-User Mode for fsck:
    fsck ran fine, reporting that it did alter something and I had hoped that this had fixed it, but as soon as I reached the desktop, the iMac crashed.
    Software Update:
    My Internet is bad enough as it is (less than 1MB/Sec, problem with living in a rural area and being on a contract until October) so I haven't been keeping up with some updates as it takes forever to download them. However,  anytime I try to update now, the computer either crashes, won't open Software Update or freezes while it goes to install the updates.
    Disk Utility:
    Found nothing wrong.
    Reinstalling Mac OSX: (Via holding down C at bootup and from the disk if I reach the desktop.)
    Either the computer freezes on the Apple logo and spinning gear (which usually doesn't even appear whenever I booted up the iMac) when I hold down C, or it will freeze/crash as the computer tries to restart opening the utilities panel if I run the reinstall from the desktop.
    Everytime I've tried to boot the computer today (day three) has resulted in the computer staying on the Apple logo and spinning gear. So without going any further, I decided to ask this to the community because nothing seems to be working, worse being the fact that I'm just on my holidays from University and I'm pretty much lost without the computer
    As for the iMac's details I'm really not sure since I generally use the "About this Mac..." feature which I can't get to now. Although I think the only important bits is that it is running on OSX Snow Leopard 10.6.8 with no external hard drives.
    I'd really appretiate any help, thanks
    Aletonum

    One of the memory cards was indeed faulty, and the other completely fine
    Thanks very much for all your help!
    Although there is one little thing that I've noticed. The iMac works properly, but I tried to software update to see if that may help my Minecraft sound issue (as I still don't think only having 2GB instead of 4GB would cause such a problem) but the software update application won't work. Running the "Software Update" from the apple menu on the toolbar gains no response, nothing happens. If I run the software update from  system preferences, the application icon appears for a second, then disappears (as in the blank app. icon, the blank canvas with the pencil, pen and ruler in the bottom right corner). It does this every time I try to run it. It did work when the computer was crashing, but this started when on one of the occasions I ran the app. while it was crashing. Since this occured during the crashes, and still occurs now, I'm wondering did something simlar happen minecraft, as it's sound disappeared during the crashes and is still gone now.
    However, the computer is now working again without crashes, which is the main thing, thanks for helping me fix the issue
    Edit: I would mark the topic as solved, but I'm unsure if this would lock the topic or something simlar, so I'd rather leave it open for any ideas regarding the software update and Minecraft issues I'm having

  • 2008 24" iMac crashing both SnowLeopard and Mavericks

    My iMac crashes about 1-3 times a day, usually while scrolling (either via scroll wheel or using mouse), or switching tasks.  Sometimes the screen goes blank (either solid grey or white, or horizontal grey or white stripes, or all black), or the screen presents the normal picture but the cursor disappears or doesn't move, or the cursor moves over a normal screen but no actions can be taken (force quit not available either by mouse or by keyboard).  Often I have Mail or Safari open but not always.  So I have to do a hard kill and then restart.  Computer restarts normally and nothing seems damaged.  Apps work as they should. 
    This problem occurred when I was running Snow Leopard, and has reoccurred after switching to Mavericks.  I keep the OS updated to the latest version of each.  My iMac has 4 GB RAM and 1 TB HD (3 partitions) currently  with TimeCapsule Router (2TB HD), but I had the same problems under Snow Leopard when running 2 GB RAM and 320MB HD and Airport Base Station. 
    When I upgraded OS to Mavericks and HD to 1TB I did disk repair using Apple's tool as well as Drive Genius3, then did a backup, and then inserted new HD and installed Mavericks to a 700GB partition, and restored from backup.  Then I used AppZapper to remove residual of all apps that would no longer run under Mavericks.  Also tried disabling all Safari extensions.  All to no avail. 
    Do anyone have any ideas?  Is this related to older HW (Core 2 Duo) and newer OS?

    Create a new admin user account in Users & Groups preferences. If you have Automatic Login enabled, then disable it. Restart the computer and choose the new account for login.
    Operate out of this new account for a day or so to see if the problems are resolved.

  • Imac crashes in pse9

    My rather new imac (intel version with lion) crashes when i work in pse. It suddenly gives 3 long beeps and my screen freezes completely. I can restart easily by disconnecting power and the mac can work without problems for hours, even when i work in pse. Then it suddenly dies again. This kind of crash never happens in any other application, nor in internet. Apple's repair unit checked the computer thouroughly and found no problem. So it seems to be a bug in pse9.0. Perhaps i should update to elements 10, but i did not find a way to update.

    I will.
