Q: Boot up after installing El Capitan

HI,

I've got stuck with white screen with Apple logo and empty progress bar underneath after installation of El Capitan. Booting up in safe mode gives the same result. I've made schoolboy error- trusted and did not back up system with time machine. Any help highly appreciated. Thank you.

MacBook Pro, OS X El Capitan (10.11)

    I also had the problem of old kexts and the Eltima Syncmate one was causing my screen to corrupt like a weird mosaic pattern at startup. After removing it in recovery mode I've had no further problems.

    I just had what sounds like this exact problem when installing the 10.11 public GM over my 10.10.5 install on my iMac14,2.

     

     

    I started the install and when I came back later, it was at a black screen with the white Apple logo, a progress bar 85-ish%, with no other text on screen. (eg, no "About x minutes remaining" or anything like that.) I think this may have simply been the boot process after the installation finished and the machine restarted itself. I am not sure since I wasn't nearby when it happened.

     

     

    At any rate, the progress bar was stuck in the same spot, and the spinning-pinwheel-of-doom was spinning for over an hour (since I noticed it was at this point) with no progress. Restarting the machine it returned to exactly the same state, even while holding shift to get it into safe boot mode.

     

     

    Next I restarted holding Cmd-R during reboot to get into recovery mode. The black screen, white Apple logo and progress bar showed up again, and the progress bar moved along to around 85% again and I thought I was screwed. About 10 seconds later the screen flickered... flickered again.... flickered really weirdly again.... and then BING! Up pops recovery mode — the 10.11 version.

     

     

    I opened Terminal, verified that all of my files were there, and then I started looking for third party kernel extensions. I hade 3.

     

     

    - TelestreamAudio.kext

    - VaraAudio.kext (the older version of TelestreamAudio.kext)

    - PromisePegasusJ4.kext

     

     

    Why the installer or boot process didn't move these out of the system extensions folder to disable them, I have no idea. But I deleted them, and then started First Aid on the disk as well, which found and fixed no problems. Restarted the machine and all was good.

     

     

     

     

    So, for me:

     

     

    - Boot into recovery mode by holding Cmd-R

    - Verify you're in the El Cap recovery mode (the font will be different, and looking in About you'll see the new El Cap icon)

    - Open Terminal

    - ls /Volumes/Macintosh\ HD/System/Library/Extensions

    - Find and delete the third party ones (be very sure you know what you are doing)

    - Do a First Aid on the HD just to be sure

    - Restart

    - Pray

     

     

    Good night, and good luck.

    The tip about the Eltima Syncmate seems to have done it for me as well. Thanks. I had read about removing the Virtual Box (kexts or plists; not sure which) and had tried that but it did not get me going. I just tried removing the Eltimate Syncmate stuff (I do not even use that software anymore so it was just left over stuff) and i was just able to do a successful reboot of El Capitan. Still more playing around to do but hopefully I am on my way finally.

     

    Thanks.

    Hi,

     

    May I know the command in deleting the files you mentioned?

     

    thanks

    Use the 'rm' command. https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/ man1/rm.1.html

     

    When removing a kext, since it is a folder, you'll want to use the -r argument, so something like

         rm -r /Volumes/Macintosh\ HD/System/Library/Extensions/ThirdParty.kext

     

    You can easily delete things unintenionally if you are not careful with this command, particularly the escaping of spaces in the volume name.

     

    Deleting a third party kext itself is safe, but deleting anything else is bad news. Make sure you really understand what you are deleting, why, and how.

    I used an app called Etrecheck to show me what kexts were loading. I then looked for ones that looked out of place, i.e. for software I was no longer using. For me it was Virtualbox and Eltima Syncmate. I then removed the kext files which are typically loaded in the Library/Application Support or the System/Library folders. Once you have located them I suggest copying any that you plan to remove in case you remove one that you actually need to put back and then once you have them copied somewhere else then go ahead and delete them before you reboot (after you have done the upgrade to El Capitan). If you come back up OK, then you should be fine (I am still messing around with it; I've done multiple reboots now and all seems well so far).

     

    Hope that helps. Good luck.

    Hi and hope you can assist me (new to the forum),

     

    Reading your notes it seems I may have the same problem for not having "El Capitan" booting up.  Used EtreCheck and at least one the problems might be same as yours. "

    /System/Library/Extensions

    [loaded] com.eltima.SyncMate.kext (0.2.5b15) [Click for support]"

    Could you please inform how to remove the error by using the "terminal function" so I can hopefully resolve the problem?

     

    Thanks in advance.

     

    Best regards, Federico

    ElmediaPlayer.kext and EltimaAsync.kext are both obviously not Apple extensions. Probably EPSONUSBPrintClass.kext, but you'd need to look at the contents of EPSONUSBPrintClass.kext/Contents/Info.plist to be sure. (If the CFBundleIdentifier starts with com.apple, then you know it's Apple's.)

     

    Try this:

         kextfind /Volumes/your-volume-name/System/Library/Extensions \( -nonloadable \) -print -pp CFBundleIdentifier -print-diagnostics

     

    That should complain about any unsigned kexts which should be the problem. But still, don't delete any Apple-supplied kexts. Only ones you can be sure are third-party. And in fact, instead of deleting them outright, it'd be smart to move them aside somewhere (like in a folder on your user Desktop).

    I had this issue and removing Virtual Box extensions solved it.. I think there were 3-4 of them starting with VBOX, however I am sure the others that are experiencing this issue may never have installed Virtual Box, and potentially some other extension is now causing the issue. These were located that \startup_disk\Library\Extensions

    Unfortunately I installed El Capitan on Oct 1st and now the OS opens with a Circle/Slash logo.  I have to open in recovery mode and it takes 40 minutes.

    This is an epic bad upgrade.

    hi,

     

    this solved the boot up issue after EC install.

    Posted by TSOPA from Reboot fail after installing El Capitan help!!

     

    Hey I ran across this fix and it worked for me on two machines.

     

    Email this code to yourself, but change the machine name to YOUR EXACT machine name.

     

    • cd "/Volumes/MacMini HD/Library/Extensions/" ; mkdir Unsupported ; mv Net* Unsupported ; mv Sym* Unsupported ; mv hp* Unsupported ; mv ndc* Unsupported ; cd "/Volumes/MacMini HD/System/Library/Extensions/" ; mkdir Unsupported ; mv Belc* Unsupported ; mv Eltima* Unsupported ; mv hp* Unsupported ; mv Hua* Unsupported ; mv Netg* Unsupported ; mv Remo* Unsupported ; mv RIM* Unsupported ; mv USBEx* Unsupported ; rm -Rf /Volumes/MacMini\ HD/Library/Filesystems/*fuse* ; rm -Rf /Volumes/MacMini\ HD/Library/Application\ Support/Sym* ; rm -Rf /Volumes/MacMini\ HD/var/folders/*

    Boot in Restore mode.

    Click OS help and Safari will open

    Open your email and copy the code

    Quit Safari and open Terminal from the top menu

    Paste the code and hit return.

    Give it a minute or two. When it is done you will then be able to quit Terminal.

     

    Restart
