    Hi GSfromNL  -

     

    I waited until yesterday (i.e., Nov 23) to DL and install El Capitan, assuming that the past 7 weeks would have enabled Apple to ensure that the critical issues had been resolved for the first to take the 10.11 plunge.   Wrong.    Thanks for all your help.  

     

    To others after me who have just discovered this problem and read this -

     

    I used GSfromNL's instructions in the reply to Markzol (Oct 11 2015 12:37 PM).  It worked perfectly.  I'll clarify a few things that were confusing to me.  You will do a search within the kextList.txt file that automatically appears on your desktop post terminal instruction.  This search is continual - you find one, copy the location line to a separate text/Word document and then proceeded to the next one via arrow at the top right.  For myself, I had four kext that were not signed.  These were as follows (this is what I copied to a separate text file).

     

    /System/Library/Extensions/BJUSBLoad.kext

    /System/Library/Extensions/EltimaAsync.kext

    /System/Library/Extensions/JMicronATA.kext

    /System/Library/Extensions/Soundflower.kext

     

    The last three were often mentioned by others in this and other threads as being not signed.  I followed GSfromNL's further instructions, finding, copying and deleting the corresponding extensions from the Locations.

     

    And then I with excitment and trepidation and restarted.  The screen went black,  it seemed like a minute but it was probably about 20 seconds and THEN..........I saw the Apple screen with the bar proceeding from the left to the right with gradual darkness. 

     

    I gave myself a great hurrah internally and then found my husband and smiled from ear to ear.

     

    Thanks again, GSfromNL.  Much appreciate your guidance.

    Glad it worked also for you!

    When it happened to me I was shocked, thought my brand-new SSD was dead!

    dear all,

    i have the same problem as many of you.

    i Can go to terminal only via utility os x.

    The first thing I see in terminal is this: -bash-3.2#

    I have tried to reach the kext extension files but I can not reach the folder using commands given on this support pages.

    on the disc utility I can check all folders and I can see that I have many kext files, but from there I can't touch any of them.

    I Need help!!

    Think you did not start with your internal hard disk. If so:

    Try the following commands in Terminal to list the kexts on your internal drive, (if asked for your password give it):

     

    cd /Volumes/HDname   (Replace HDname with the name of your harddisk. If there is a space in the name put in a slash before the space like HDname\ XX)

     

    Then, but be VERY careful with these commands and use correct Uppercase and lowercase...!

     

    sudo ls -1 /Library/Extensions/ ; sudo find /System/Library/Extensions -ctime +1d -depth 2 ; sudo find /Library/Extensions -ctime +1d -depth 2

    This will give you all the kexts to sort out, if you found them:

     

    Make different locations for the not supported kexts with these commands:

    sudo md ~/System/Library/KextNotSupported

    sudo md ~/Library/KextNotSupported

     

    Move all suspects to the different location with these commands:

    sudo cp ~/System/Library/Extensions/EXACT KEXT NAMES  /System/Library/KextNotSupported

    sudo cp ~/Library/Extensions/EXACT KEXT NAMES /Library/KextNotSupported

     

    Delete them in original location:

    sudo rm ~/System/Library/Extensions/EXACT KEXT NAMES

    sudo rm ~/Library/Extensions/EXACT KEXT NAMES

     

    Repeat for every suspected kext.

     

    Note: replace EXACT KEXT NAMES with, for instance, EtimaAsync.kext and, again, use the EXACT Uppercase and lowercase...

     

    Hope this helps!

    Interestingly this problem only occurred on my, somewhat old, MacBook Pro when I updated from 10.11 to 10.11.1.

     

    However the solution still turned out to be cleaning out the "obvious" crap kext files.

     

    Thanks for the advice from those who contributed.

    I've had the same problem for many months and tried various solutions suggested in this forum and others with no luck. Contacted apple via chat and they denied being aware of the issue and suggested I reinstall OS X

     

    Anyway, I found this solution here which worked for me:

     

    http://apple.stackexchange.com/questions/126288/xcode-5-1-wont-launch-being-upda ted-but-already-installed

     

    1. Show the App Store's Debug menu:
      defaults write com.apple.appstore ShowDebugMenu -bool true 
    2. Select Reset Application and restart the App Store
    3. Log in to the App Store through the Purchases tab.
    4. Reboot.

    Apologies if someone has already posted this but I don't have time to read the whole thread

    Can´t believe apple did this to us    . Considering the number of people claiming, they already need to give us a solution..

    Thank you very much GSfromNL!  You made it easy for me.  Made your lists that you described very well, used the Finder to dump stuff.  I dumped the one that everyone seems to see, the Eltima, and also dumped one for a Wacom Pen Tablet.  The pen tablet one had inspired some sort of incompatibility warning somewhere during the update process, so I dumped it.  Was prepared to dump a bunch of unsigned stuff from Logitech, USBOverdrive & Canon, but left them and tried a restart.  Two consecutive restarts with no issues.

    Thank you, you are a wizard!

    Thanks,

    but... do you only x-code or the whole boot process?

    Same issue with El Capitan.

     

    1. I was able to finally get to Recovery in order to go through the interminable re-install of El Capitan. Once that was finished a software update was started for Office.

    2. Unsuccessful reboot that now hangs at the White Screen of Death (before I had Apple's Gray Screen of Death0

    3. No ability to do Command Recovery

    4. Holding down option to get to Disc Recovery now doesn't work either.

     

    I am worse off HAVING re-installed El Capitan. My Imac is dead. El Capitan killed it

    How do you go back to Yosemite? B/c El Capitan is lethal

    I"m surprised your comment wasn't censored. Mine was: complaining about Apple "geniuses" lack of interest in an obvious critical problem. This post will be censored too b/c it is Micro-softesque incompetence that is making it impossible to use my Imac for work productivity purposes.

    This is what sent me spinning back to ground zero.

     

    Was able to do that full El Capitan download from the App Store (should be called Death Valley not some majestic mountain peak). Got everything back to normal. Was then prompted to update the download for Office via my automatic software update prompts.

     

    Fatal mistake!

     

    Went from Apple Gray Screen of Death to Apple White Screen of Death and interminable re-boots.

     

    Have not tried the Kext removal. The wannabe geniuses at the Apple Genius Bar were totally clueless on this issue and just wanted to take my wallet for a service call.

     

    Very disturbed by the continual Microsoftian lack of interest or concern about these major OS problems by Apple Corp. I guess I should have been "happy" when Yosemite only killed my Internal DVD drive. El Capitan has me dead in the water.

     

    It's like the Bill Murray movie Groundhog Day

    I Must be the only one this hasn't worked for. When I followed your instructions in Terminal it found no KextList.

     

    havent been able to access Disk Utility in Command Recovery since to re-try

    Many thanks, I was at my wits end on this one. In my case the culprits seem to be Blackberry/RIM, Harmony (remote control for AV systems) and 3Dconnexion (a 3D mouse I last used a long time ago). Not sure if it was some or all of them.
