HI Max108! I am sweating cold here and you seem to be the one with all the right answers - can you please help me? I have the same problem as the others here. I have been able to reinstall El Capitan and I am too afraid to reboot it now. I have taken the liberty of running the inital command you recommend for otherts with similar issues and this is the output:

ACS6x.kext

ATTOCelerityFC8.kext

ATTOExpressSASHBA2.kext

ATTOExpressSASRAID2.kext

ArcMSR.kext

CalDigitHDProDrv.kext

HighPointIOP.kext

HighPointRR.kext

PromiseSTEX.kext

SoftRAID.kext

Any idea on whether this points to a probable cause? What can I do to reboot safely again? Thank you so much from sunny Brazil

Hi Max108!

Thank you - you have saved my life!!!

Just our of curiosity: what exactly happened? How did you pinpoint the exact culprits? When should I try to reinstate what was moved to the "Unsupported" folder?

Thank you again - I will have a good night's sleep now 🙂

You're welcome!

Through troubleshooting these issues with people on these forums, I've discovered that El Capitan's new security measures don't mix well with a surprisingly large number of 3rd party kernel extensions (kexts) - it fails to handle them properly and causes OS X to fail to boot.

Of the kexts in the Unsupported folder, Soundflower and EltimaASync are definitely best left there. In general, when updating to a new version of OS X, it's worth checking for updated versions of all software that employ kexts - preferably they should explicitly support the new platform before installing them, but id depends on the software.

Anyway, glad it's sorted for you 🙂
