Mac cannot start after el captain

Cannot start after updating mac

Safe Mode boot removes the system caches that can help after an OS X day or level.

Follow these steps to start in safe mode.

  1. Start or restart your Mac.
  2. As soon as you hear the startup tone, hold down the SHIFT key.
  3. Release the SHIFT key when you see the logo Apple appears on the screen.

After the Apple logo appears, this may take longer than usual to reach the login screen or your office. This is because your Mac performs a check of directory of your drive to boot in safe mode.

To leave safe mode, restart your computer without pressing any keys during startup.

Try safe mode if your Mac does not end commissioning

    Hello

    1. have you successfully install the update?

    2. are you able to connect to the desktop without any problem?

    Was the message you saw before Windows starts, the system applying these updates. This is a normal procedure that Windows takes above all the critical updates are applied. If you were not able to start Windows, then we might have a problem with Windows update.

    Regarding your second yellow exclamation on the wide area network WAN miniport, you need to update the driver for the network adapter.

    The Code 10 error applies mainly to the problems of hardware driver and devices or compatibility problems between the drivers of equipment and additional software that is installed in Windows. Therefore, we recommend that solve you these problems with emphasis on device drivers, configuration of device problems and hardware compatibility issues. You may need to update the chipset drivers and the network adapter.

    I suggest you run the automated FIXIT from the link below and.

    Select disk utility, then click on the continue button.

    Hello, I have a problem after I updated my blackberry for Mac OS 10.2 Z10... When I restart the phone it don't finish loading up to 99% only... do not start on my phone... I wait about 6 hours on hold to finish loading and start but only 99% 3 days now since I update this... I never use my phone...

    can you please help me solve this problem?... what would I do?... I try to reset holding power button / stop and volume up and down but it's the same output... loading only... Unable to start...

    Please help thanks!

    Hello and welcome to the community!

    Please try to remove the battery for 5 minutes, then put it in and start the system again. If this behavior continues, then look for an auto-loader in order to force a clean reload OS... something on the operating system that you have installed is perhaps corrupt, and a clean reload would be a way to fix it.

    Good luck!

  • Portege 2000 cannot start after suspend

    Hi guru,.

    I'm new to this forum. So I looked through the first forum hoping to get an answer to my problem before posting, but no good result.

    Here's my problem. My portege 2000 works before brilliantly. But last night, while I was trying to configure my APM suspend (this is the first attempt to suspend), the problem, the system freezes! Then I tried to restart, can not remember I turn it off by pressing the button for a few seconds or unplug the hand because of the power key is not, in any case I have wait a few seconds after that, then turn on the power again, but the system seems to be dead, the AC power led is under voltage green LED, battery was not in the slot so no sign for her, the small button Fn LED told me this Fn key works well, but the caplock key does not work because its LED is not turn on after pressing, the screen is blank, or should say it is not powered on, the hard drive does not turn.

    So I unloaded the system by unplugging it from the main. After a while I swhitch on once again, the laptop is still in the same situation. Therefore, I tried to unload everything, disconnect the hand, open up the laptop, unplug the CMOS battery, wait for a while (15-20 minutes), then put it back on, but no joy.

    I did some research on Google at this time and read the knowledge base on the web site of Toshiba, seems the problem come with BIOS, who say that the system does not start if the power is off during suspend mode for the original version of BIOS (later healed). So, I decide to Flash a BIOS to most recent version. I have a pc card floppy drive, so I download the BIOS and create the floppy, then I use the key to update the BIOS to power on the laptop, luckily this time it works, "ready to update bios" screen appear. But when I press the key on the keyboard, it seems that it does not access the pc card floppy drive.

    By this incident, I think that the material has no problem, but the system is in standby for ever. Guru of the idea?

    Therefore, I have 2 questions:
    1. how to make it back to the start mode so that I can start my system? I need this as well according to the Readme of the BIOS update package, it should be in start mode, no interruption/recovery mode.
    2. how flashing a new bios in this situation? Do I need a USB floppy drive to do the BIOS to recognize that there is a drive so that I can Flash a new bios in there? Or the system will analyze not for material in this mode 'freezes '?

    Sorry about the long story, but I think I must tell him that you guys understand the situation and what I've tried so far.

    Additional information on my system, I'm under debian linux etch on this laptop, and everything that happened after I typed the command "apm-s". But it seems to me that it is the problem of BIOS problem OS?

    Thanks in advance.

    concerning
    Colin

    Hello

    First question: How did you install the operating system if the laptop will not start?

    I'm a bit confused Mr. I put t you know what means the boot mode.

    If the laptop has been completely stopped down so it s in the boot mode (standby or hibernation mode don t mix).
    If you want to update BIOS please make sure the BIOS is good and that you use the right update procedure.

    Where did you find the information that the BIOS update will solve this problem?
    In any case, for me, it looks more like an electrical problem on the motherboard.

  • Satellite A30 cannot start after cleaning the heatsink

    I have a problem with my sat a30. It lights for 5 seconds then goes automatically off and on again for 5 times, before finally shutting down completely. all this began after I cleaned the heatsink. can you give me some advice for what to do with this problem?

    Hello

    This path is not easy to say what is the problem, because, who know what did you exactly and how. As you know do something like that on your own is always risky.

    Are there signs of life of the cooling fan? AFAIK the CPU becomes very hot in just seconds after the start, and I presume that CPU is not cooled properly and because of this unit turns off.

  • a1720n cannot start after the installation of the DVD from LG GGC-H20L drive

    I installed the unit and connected to the second channel SATA (blue) and the computer would not start.  Disconnected and the system returns to normal operation.  It appeared that the system was able to read a correct reader type in the BIOS.  I couldn't find any instructions online documentation SATA configuration.  I will apprecaite the ideas or the BTDT there!  Thansks!

    Thanks for your quick responses!  I advanced and tried to just connect the drive again and the system booted properly.

    When I said that the system does not boot, it would go beyond the BIOS screen but should restart after trying toload windows.  Subsequently an any a GUI recovery came, ather than aloowing system to restore from an earlier time, I told him to try an automatic recovery.  This process was then several minutes before failing.

  • Win7 (Home Premium) cannot start after "important update"

    I just bought a new PC with Windows 7 Home Premium pre-installed. After an update that Win7 launch is no longer, instead the PC reboots from the BIOS. Now, as I write to you from my old XP system, I do that I can't do this post shouldn't indicate that I found a solution. Using the utilities available / suggested at this stage, I can't understand what the 'important' update was so am not able to retrace the steps that may have caused problems. Currently, I run the system recovery, so maybe in a few minutes, I might be able to use the WIN7 PC again. However, I would like to know if anyone else is / has been faced with this problem.

    Hi isamart,

    First of all, I suggest to start the computer in safe mode and see if you can boot to the desktop.

    To boot to the desktop in safe mode keep tapping key F8 during restart. Once you see the option to start in safe mode select and press to enter.

    Access the link to learn more about how to start the computer in safe mode: http://windows.microsoft.com/en-US/windows7/Start-your-computer-in-safe-mode

    If you are able to access safe mode, you can try to check the update installed on your computer and remove it and check if that helps.

    To view and remove the updates installed, follow the steps below.

    1. click on start

    2. in the start search box type appwiz.cpl, and then on enter.

    1. click on view the updates installed in the left pane.

    2. take note of the recently installed update in the list and remove the update.

    3. restart the computer and check if you can start.

    If the steps above fail, you try to perform a system restore on your computer to an earlier date and check if you can boot to the desktop.

    To restore the operating system to an earlier point in time, follow these steps:

    1. Click Start, type system restore in the search box, and then click System Restore in the list programs.

    If you are prompted for an administrator password or a confirmation, type your password or click on continue.

    2. in the System Restore dialog box, click on choose a different restore point and then click Next.

    3. in the list of restore points, click a restore point created before you started having the problem, and then click Next.

    4. click on finish.

    The computer restarts and system files and settings are back to the State they were in when the restore point was created.

    Access the link below to find more information about the system restore.

  • Aspire E3 - 112 cannot start after win10 own attempt installed

    The installation is wrong. He went right through the extract process and install OK but then just went along in a loop to keep reinstalling the usb drive. I changed the bios by promoting usb hdd over windows Boot Manager (in uefi). So I removed the USB drive and restored the order of the bios. But now, when I boot, I get an error window saying "the computer restarted unexpectedly or encountered an unexpected error." Windows Setup cannot continue. To install windows click OK to restart the computer, and then restart the installation. "It makes no difference if I close the window or click OK, it goes through the same circle.

    Help!

    Thanks for the reply. I tried that. In the end, I found that the solution was to wait for the beginning of the (umpteenth) reinstall the process and then press the power button for a few seconds until the machine stops. Then I powered up while pressing the F2 and is gone in the bios where I restored the original and the machine parameters and then started in the new clean install.

    Unless the OS is nuked, how to perform a clean install is using the settings > update & security > Recovery > restart now and use the boot from usb option. And leave the bios alone.

  • HP Pavilion DV4-1125nr cannot start after the update/update BIOS version F.12 to d.55

    System: HP Pavilion DV4-1125nr PC Notebook

    Product #: FR922UAR #AB

    The system board ID: 30F7

    Version of the BIOS (before the update): F.12

    OS: Windows 7

    I tried to update the BIOS to d.55 which was provided by HP. After the successful installation the closure of new windows BIOS correctly. I restart the PC, HP Logo appears and then nothing happens. The operating system do not load or start at all.

    I also tried to boot using the Windows 98 Second edition CD (to charge BACK), but it did not work.

    Please help me...

    Fortunately I found a Solution to this problem.

    Here are the summaries (and modified according to my needs) the steps that I've taken of the following thread:

    http://h30434.www3.HP.com/T5/notebook-hardware/dv4-1140GO-won-t-boot-after-flashing-latest-BIOS/m-p/19698#M2730

    1. go to the hp site and download the correct version of your BIOS. In my case it had to F.12. Why not the latest version? Because there is no guarantee that the last one will work for you, know after measures.

    2. go where you downloaded the file and using 7 - Zip (or tool of your choice of course) unzip the contents to a folder of your choice. We'll get to that later, so keep this file open.

    3. use 128 MB or no matter what key-USB USB key (the smallest, you might find, because they said the smaller the better ) and reformatted to FAT or FAT32 click with the right button on the drive by clicking on "format".

    4. now that my USB is ready, go back to the folder where you extracted the file to update the BIOS (always open to the right of the folder?)

    "5. If you have the graphics card Intel integrated like me, copy the ' 30F7F12U. FD"of the key USB and RENAME the file '30F7F12U. FD' at '30F7. BIN ". Remember that this name calling to order "DV4-1125nr. If you have a different motherboard, the system or the BIOS, the name must be determined according to the.

    The next steps are exact 0.0 as follows (the link of a full detailed discussion is provided below), I simply numbered:

    6 unplug the adapter from the laptop.

    7 remove the battery from the laptop.

    8 insert the USB key into one of the USB ports on the laptop.
    Does not seem to matter which.

    9. press the 'Windows' key and the 'B' key

    10. connected to the power adapter.

    11 press the 'Power' button on the laptop.

    12. when the LED is entered, letting go of the power button / stop and the two keys down earlier.

    13. After about 10 seconds the notebook started to read the USB key. While searching for the file, the laptop beeps every seconds.
    The number of beeps varied, depending on what size of the key USB has been and
    the number of files on the USB key, a single beep for many.
    If the file was not found, the laptop will restart and try again.

    14. If the file is found then it took about 12 seconds for the laptop to load. No beeps sound not heard during the loading time.

    15. when it is responsible for the laptop has started flashing, indicated by beeps every 2 seconds. It took about 32 seconds.

    16. about 5 seconds after the ringtone had stopped off the laptop computer.

    First I update my pc with the last BIOS (F.66), but did not work for me (operating system not loaded after HP Logo ). So I decided to go back to the old F.12 (the version that has been shipped when the laptop was purchased) according to the procedure described above. But the problem is where to find version F.12 as HP currently provides links only for the version of the BIOS F.66 to d.55 (in the drivers from the hp support site section)

    Fortunately, I found a direct link to this version F.12 in the next thread.

    http://Forum.NotebookReview.com/HP-Compaq/304332-C700-CQ40-CQ45-dv4-dv5-DV6-hdx18t-Insyde-BIOS-recovery-using-USB-thumbdrive-2.html

    F.12 version:

    FTP://ftp.HP.com/pub/SoftPaq/sp40501-41000/sp40749.exe

    This was F.12 and worked for me. Thank God Almighty I return my PC.

    Thanks to all who contributed in the discussions above.
