No need to delete, idea was a great, just edit a bit and it will work for everyone...!
I finally got the Kexts and removed them to an unsupported folder. I will see when I reboot...
I t has worked GSfromNL
Glad it worked for you as well. Cheers!
BTW, I'am an old programmer dog from the MS-DOS days, from before and after, (Cobol, Assembler, PL1, who cares these days...) spended hours and days to solve my business Windows problems... With Mac, sporadical, but now kind of back in the old days. Should I be happy...?
The steps provided by Lucaspeed helped me.
However, since "com.apple.kext.caches" was a folder and not a file on my machine, I changed the command
rm com.apple.kext.caches
into
rm r com.apple.kext.caches
That's right!
I was writing from memory and I totally forgot that parameter.
I tried to edit my original post but seems impossible once someone replies.
The right command is:
# rm -r com.apple.kext.caches
I did the El Cap ugrade and no matter what I tried, it froze just between end of progress bar and login screen. Then rebooted, then could not find startup drive. Safe mode did the same thing. Resettin PRAM, NVRAM no good.
Fortunately, I always make a bootable usb stick installer and several bootable backups before doing these installs. No diagnostic would indicate what it was. So, I formatted my drive, did a test clean El Cap install on the same drive, which worked fine. This indicates that some drive problem, old files, drivers, loading programs, or something else on my Yosemite was not liked by El Capitan.
The fix was to do the clean install, then use migration tool to migrate everything from one of my fresh backups. This worked like a charm and left whatever the problem was behind.
Always have a fresh backup and always make a bootable OS usb stick installer before doing these JIC.
Hi, I have the same problem, cant boot after updating. And the kext theory sounds likely. But I havent a clue which files could be cuasing trouble. I copy my list here and if anyone would like to help finding potential candidates for removal please let me know!

ps
I tried the cmd S but that gave nothing...
Hey
How do I get a list of the kexts files?
thanks
Thanks a lot, it worked for me (iMac mid 2007)!
I just had to remove these three entries:
APExtFramebuffer
AirParrotDriver
EltimaAsync
Regards,
Alfio
Hi Pierre, suspects are the kexts starting with:
Etima
Jmicronata
ssuddrv
Move them to a different folder and try booting, think you're fine after that.
Hi Tsofa,
Look at my previous posting, but here again:
1) Open Terminal in /Applications/Utilities
2) Enter "system_profiler SPExtensionsDataType > ~/Desktop/kextList.txt" without the quotes and hit return (this will take a short while to run).
3) There should now be a kextList.txt file on your desktop, open it and press both the "Command" and "F" keys to bring up the find.
4) In the find field insert "Not Signed" Copy the destination to the .kext file to a list for use later. (Click next to cycle through all of them.) Example: /System/Library/Extensions/JMicronATA.kext
5) Browse your drive to /System/Library/Extensions and create a folder by the name Unsupported, move any of the unsigned kext files to the folder Unsupported. Delete the Kexts from their original location.
6) Browse in /Library/Extensions and create again a folder named Unsupported. Look if there are more unsupported Kext's and move them to the folder Unsupported. Delete the Kexts from their original location.
7) Beware that there may be Kext's that are "not signed" that you want to keep because you may need them for programs known and trusted by you, so do not move them to the unsupported folder(s). If you did, no worries, you can always put them back later if there are troubles.
8) Reboot and you should be all set.
Cheers!
WHen comes Apple with aan update? The installation of this El Capitan is a desaster.
Glad it worked for you...
Geen idee!
Think and hope next update will solve these and other things. Are you OK for now? If any problems, post them, many knowledge in these fora... :-)
