since upgrading to OS lion, my mac book pro (2010 August) keeps freezing (non responsive, requires restart) when i turn on my mac and the system is trying to open apple mail. while apple mail is attempting to collect new mail, the macbook pro freezes. this happens every 2nd time i try to start up my computer. this only started happening after i upgraded to OS lion. please let me know what I need to do to fix this. being forced to restart every 2nd time i turn on my macbook pro has been very frustrating. not sure if apple mail is also the cause of my macbook pro for being very slow during start-up (on the occasion the computer doesn't freeze).

I am having similar 'freezing' problems with many programs (Mail, Safari, iTunes, etc.). I have done a clean install of Lion instead of an upgrade when it came out. Perhaps something went wrong with my install? I'm thinking about wiping and reinstalling.

  • My 06' Macbook Pro crashed with vertical, green pixelated lines and now will not advance past the turn-on screen with the apple filled with green lines as well. Then, it says to hold down the power button to restart. Help?

    My 06' Macbook Pro crashed with vertical, green pixelated lines and now will not advance past the turn-on screen with the apple filled with green lines as well. Then, it says to hold down the power button to restart. I have tried several times to get it past this point but tnothing helped.
    I have an appointment at the Apple store today, but was wondering : will all of the information and files on my desktop be lost? Or is this a logic board problem?
    Any help is much MUCH appricated.

    I'm not sure, if you're out of warrenty it'll cost quite a bit for the replacement of the logic board replacement...unless you have apple care. you could ask apple to try and recover your hard drive but i'm not sure.

    10.6.8 update won't install gets half way through then just freezes spinning beach ball for 4 hours any ideas y. Tried and restarted 3 times already does the same thing each time have to hold down the power button to restart. Anyone can help

    Ok will check, as of right now I have 82.57gb free, that's plenty of space will check the disk though using disk utility. Also I am now downloading the update from the apple website instead of going through software update

  • Why did the screen on my MacBook Pro turn black and ask me to hold down the power button to restart and then when I restarted it. ALL the work i had done was gone???

    How do I get back what I lost. When I was forced to shut down my computer?

    None of us knows why your screen turned black - it's the most serious form of crash, and yes, almost all the changes that you didn't save are lost.
    An exception are the audio recordings - they should still sit in the project package of your song. Locate the project in the Finder, ctrl-click it and select "Show package content". The Media folder will contain all your recordings.

  • Kernel Panic: You need to restart you computer. Hold down the Power button until it turns off, then press the Power button again.

    I apologize for writing a book, but I think explaining the full story may possibly get me a correct answer.  I hope that someone can give me some insight as to what is the problem with my MacBook Pro.  I have a MacBook Pro (15-inch Early 2008), model identifier: MacBookPro4,1 running OSX Lion 10.7.5 with 6 GB memory.  My wife first noticed a problem with the display.  Every so often it would get fuzzy with jumping lines going across the screen making it vitually unviewable.  The final time that incident took place the computer froze which required holding down the power button to restart the computer.  The computer started up to the point of the Apple logo and the spinning gear for quite some time until the screen darkened from top to bottom displaying the following message in five different languages: "You need to restart your computer. Hold down the Power button until it turns off, then press the Power button again."  I have read other blogs and support communities where people get the message intermittently, but my computer would not go past that point no matter what.  Through research and the Apple Store I was told that this is a Kernel Panic.  The so called "Apple Genius" at the local Apple Store was unable to get the computer to boot past that point even with his gadget.  It would not startup in recovery mode, safe mode or off of a disc.  I forget exacty what he told me, but he said it was getting past the first two startup steps, but it would not get past the third step which is to mount the desktop.  He guessed that it may be a problem with the hard drive; a loose wire or something or other.  I disconnected the hard drive completely and took it out.  Everything appered to be connected properly.  Then I installed it back correctly, but it did not solve the issue.  So I guess I disproved his theory of a loose wire...  I purchased ProSoft Data Rescue 3 and connected my MacBook Pro to another Apple computer using a firewire 400 cable.  I was able to get everything I needed off of the hard drive.  I did some more research and I decided to restart the MacBook Pro in verbose mode (holding down the command button and V button).  The computer magically started up!!!  I was upset that I wasted my money on the ProSoft Data Rescue 3.  I managed to take additional items off of the computer and back it up on to an external hard drive.  After some time the computer froze.  I repeated the power button process to restart and received the same kernel panic.  I managed to get the computer to startup approximately six or seven more times via verbose mode; each time the computer staying on for a shorter amount of time before it would freeze.  I managed to run Disk Utitlity.  I performed first aid to fix the hard drive and it said that the hard drive appeared to be fine.  After first aid I erased the hard drive and booted off of a Lion disc to perform a clean install or an erase and install.  Lion installed until the progress bar got the the end where I received a message that there was an error installing Lion, please try again.  Each time I attempted to install the software I would receive the same message.  Eventually the computer would not boot from the Lion disc.  I went back to the Apple Store and the Apple Genius was able to get the computer to boot off of his gadget where Lion istalled completely.  I set up the computer as a new computer.  He said that he partitioned the hard drive as DOS and then back to Mac OS Extended (Journaled) which would get rid of any errors the drive may have had.  He guessed that the problem was the hard drive, but was not exactly sure.  When I brought it home I installed all of the software applications I had on it previously.  Approximately three days later, which may have been the fifth of sixth time starting up the computer, the display became fuzzy again and the computer froze.  The computer did restart once and I was able to retreive a "log" which I have pasted below.  After if froze for the second time it restarted once using verbose mode and froze almost immediately.  After holding down the power key to shut it down and then restart; I received the same kernel panic after the Apple logo and spinning gear which put me right back to square one.  Now the computer will not boot via any method.  It freezes at the end of verbose mode which forces you to hold down the power button to shut down.  I also read that poorly seated ram may cause this issue, but I removed and installed the ram multiple times.  I even purchased new ram from Other World Computing (Mac Sales) 6 GB, but that did not make a difference.  I think I may see six possible problems on the verbose screen mode, five errors and one warning; I will type them out here:
    1. SMC: :smcReadKeyAction ERROR: smcReadData8 failed for key $Num (kSMCKeyNotFound)
    2. SMC: :smcReadKeyAction ERROR: $Num kSMCKeyNotFound(0x84) fKeyHashTable=0x0
    3. SMC: :smcInitHelper ERROR: MMIO regMap ==NULL - fall back to old SMC mode
    4. WARNING - ACPI_SMCCtrlLoop: :initCPUCtrlLoop - no sub-config match for MacBookPro4,1 with 8 p-states, using default stepper instead
    5. SMC: :smcReadKeyAction ERROR: smcReadData8 failed for key MOTP (kSMCKeyNotFound)
    6. SMC: :smcReadKeyAction ERROR: smcReadData8 failed for key BEMB (kSMCKeyNotFound)
    I was hoping that someone could read my log to ascertain wether or not they see a problem that stands out.  I was also hoping that someone could tell me if verbose mode provides any information that may be wrong with my computer.  I just hope that someone can give me some insight as to what may be wrong with my computer.  If it is the hard drive I will easily replace it, but I want to make sure that is the problem first before I waste money on a hard drive or anything else.  Please let me know if anyone requires any other information from me.
    Thank you!

    I had already written a book and I did not want to bombard people with more information, but in my previous research I did come across the major issues with the NVIDIA card.  I also was well aware that Apple offered a replacement program that ended in December of 2012.  I was going to add that in my original post, but I discounted that theory because I put my faith in the so called "Apple Genius" when I made my second trip to the Apple Store.  I brought the NVIDIA card issue to his attention and asked him if he thought that may be the problem, but he said no.  He said if it was the NVIDIA card that the screen would be completely black and there would be no startup chime.  When I experienced the screen issues I thought it was a problem with the NVIDIA card or the logic board.  I asked myself, how can a flawed hard drive cause the screen to act funny.
    nbar and Rick Warren, I thank you both for your help and insight; people like you are the real "Apple Geniuses."  I was hoping there was a way I could wipe the hard drive before I dumped the computer or attempted to sell it.  I guess I will look into purchasing a new machine when I have the funds.  Again...thank you both!

    Ok, sounds like the safe mode boot worked... You probably don't want to always be in safe mode though (some reduced functionality) so does it do a normal boot now? If not, you should then reboot into safe mode and run Disk Utility. Then select Macintosh HD on the left hand side, and click the Verify Disk button. If needed, it will ask you to Repair Disk. If there are errors found, Repair Disk again until there are none. Then try another normal boot and reply with result, wether good or bad.

    Hello cass528,
    I would be concerned too if my MacBook Air would not power on.  I recommend following the steps in this article when experiencing an issue like this:

    I watched a video on my iphone, and it worked fine. 
    I wanted to watch it on our MacBook for sound and clarity, and every time I accessed it, it locked up. To the point that the only solution was holding down the power button.
    Everything else worked, and I could freely enter information and open other Facebook entries, but when hitting the "play" button or clicking on the video it immediately bought up the spinning beach ball, and would never clear. Any solutions?

    Did you try viewing the video in a different browser? Firefox or Chrome maybe?

  • I just installed OS X Yosemite on my MacBook. I now cannot get the computer to start up. If I hold down the power button to try and power it back up, it will not start. Any ideas on how to fix this?

    Reinstalling OS X Without Erasing the Drive
    Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Reinstalling OS X Without Erasing the Drive
    Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
    When the recovery menu appears select Disk Utility and press the Continue button. After Disk Utility loads select the Macintosh HD entry from the the left side list.  Click on the First Aid tab, then click on the Repair Disk button. If Disk Utility reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit Disk Utility and return to the main menu.
    Reinstall OS X: Select Reinstall OS X and click on the Continue button.
    Download and install the OS X Yosemite 10.10.3 Combo Update.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    Alternatively, see:
    Reinstall OS X Without Erasing the Drive
    Choose the version you have installed now:
    OS X Yosemite- Reinstall OS X
    OS X Mavericks- Reinstall OS X
    OS X Mountain Lion- Reinstall OS X
    OS X Lion- Reinstall Mac OS X
         Note: You will need an active Internet connection. I suggest using Ethernet

    Yes I checked it.  As far as I can see I did everything Apple said to do.  I took some screen shot so you can see how the screens are connected and what and where the code is, and what it does when I drag the cancel and done bar buttons to the exit

  • After we installed a new airport extreme, the imac running snow leopard displays black box msgs saying to hold down the power button and or the reset button and then restart your computer. Can anyone provide info that can help resolve this issue?

    Experiencing similar issues on both imac and power book: after replacing an original airport extreme with a new airport extreme both computers display a black box msgs that reads: "...turn off your computer by holding down the power button and or the reset button for a few seconds and then restart your computer."...
    one of the printers are usb'd to the imac. The printer is not "seeing" the imac nor will it print wireless from the powerbook which was the norm prior to the upgrade on the airport extreme.
    Upon restart, the imac does not "see" the wireless keyboard or the mouse until it is "found" again.
    At this time the imac or the powerbook can get on line.

    It sounds like your computer is getting Kernel Panics. Please look at About "You need to restart your computer" (kernel panic) messages and if the message seen on your display is like the one in the link then you have confirmed you had a KP. KP's can be tough to track down because they can be caused by software or hardware. The first place to start is to post the complete crash log so we can look at it, often there are clues in the log.

  • "You need to restart your computer. Hold down the power button for seve..."

    Hello,
    I have recently been getting this same message "You need to restart your computer. Hold down the power button for several seconds or press the Restart button." whenever I start up my computer. It happens about 95% of the time. I have been reading on different forums that I should reset the PRam and the NVRam and I have been doing so and it does help as it does EVENTUALLY start up (sometimes takes me 5-10 min. to get it to start up).
    I have also read that it may be the RAM that is loose, so I did check that and made sure that the ram is properly placed (which it is).
    I don't know what else I can do. Should I reformat and reinstall Mac OS X?
    Here is the exact error form the dump:
    IOAPIC: Version 0x20 Vectors 64:87
    AppleACPIPlatformExpert::start failed
    panic(cpu 0 caller 0x55c095): "Unable to find driver for this platform: \"Macbook 2,1\".\n"@/SourceCache/xnu/xnu-1504.9.26/iokit/Kernel/IOPlatformExpert.cpp:1389
    Debugger called: <panic>

    Well just got around to installing the new HDD and RAM yesterday, and I am sad to say... that the problem persists. :/
    I reseated the memory and made sure they were in there properly, and I also installed the HDD and ran DiskUtility before I erased/reformatted and installed a fresh version of MacOSX Leopard, then updated to Snow Leopard.
    As long as I am using my computer everything works fine, the problem occurs when the machine is shut off or put to sleep for a long period of time. Because when I shut it off and turn it right back on a few minutes later it works, or if I shut the lid and open it 10-20 min. later everything works fine, it's only when the machine is off or asleep for long periods of time.
    So, I do not know what else can be wrong.
    Should I try to take out the old RAM and just leave the new module in and see if that works out? See if that specific module is faulty?

  • What does holding down the power button do?

    I was having trouble with my OSX 10.4.10 upgrade. I held down the power button to force it to shut off. But when I pressed the power button, I held it down...It made this loud chime and the little light on the front of my MacBook flickered very rapidly.
    What happened and did I mess something up?
    Thanks.

    A normal power down goes through steps to shut down software. Holding down the power button bypasses those steps. Normally you hold down the power button only if all else fails -- the system won't respond to normal commands, so you can't pull down the apple menu and choose shutdown.
    In most cases this "hard shutdown" isn't a big problem. However if you have files open in applications, a normal shutdown gives the applications a chance to save them. This won't. In a normal shutdown, the operating system makes sure to put the files on the hard disk into a consistent state. This bypasses that step.
    In older operating system a hard shutdown could leave your hard disk in an inconsistent state, possibly losing files or directories. But recent versions of OS X have file systems that are carefully designed not to do that. So in fact a hard shutdown shouldn't cause any damage. But if you're in an application with a file open, you will lose the chance to save data.
    I would try to avoid hard shutdowns, but in fact they shouldn't cause trouble.

    how do i reload 10 4 x when my system will only shut down by holding down the power button. G4 Imac 17"

    Power down, hold the Mouse button AND the Option/alt button down at bootup, that should open the CD/DCD tray & you can insert your Install Disc, as well as giving you boot options.
    "Try Disk Utility
    1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
    Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
    3. Click the First Aid tab.
    4. Select your Mac OS X volume.
    5. Click Repair. Disk Utility checks and repairs the disk."
    http://docs.info.apple.com/article.html?artnum=106214
    Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
    (Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
