prodiigwc Posted April 11, 2017 Author Share Posted April 11, 2017 The commands below return an error when the last line was executed, then I used the command 'sudo kextcache -i /' and it worked for me (aka, all kext I installed in the HD using EasyKext Pro, and not leave nothing in the 'Other' folder in EFI) Command that I had problems: Sudo chmod - Rf 755 / L * / E * Sudo chown -Rf 0: 0 / L * / E * Sudo touch -f / L * / E * Sudo chmod -Rf 755 / S * / L * / E * Sudo chown -Rf 0: 0 / S * / L * / E * Sudo touch -f / S * / L * / E * Sudo kextcache -Boot -U / I removed the kext 'IntelBacklight' kext because it was conflicting (and also because it did not work) I added the kext 'IO80211Family', which is a responsibility for an Ethernet port and a WiFi card to work So I have a screen with brightness that seems to be at 50% (I can not increase or decrease) and a notebook without sound ... Here's my EFI folder and the kexts installed ... Arquivo Comprimido.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 11, 2017 Moderators Share Posted April 11, 2017 Remove AppleHDA patch #5 no spaces in the directory as you have above, run again until successful output just copy and paste so you don't have error Sudo chmod - Rf 755 /L*/E* Sudo chown -Rf 0: 0 /L*/E* Sudo touch -f /L*/E* Sudo chmod -Rf 755 /S* L*/E* Sudo chown -Rf 0:0 /S*/L*/E* Sudo touch -f /S*/L*/E* Sudo kextcache -Boot -U / Link to comment Share on other sites More sharing options...
prodiigwc Posted April 11, 2017 Author Share Posted April 11, 2017 Unfortunately it did not work, my friend. I ran the first time the commands and ended up giving an error regarding kernel construction, after invalidating the kexts cache I restarted my notebook and ran the commands again, which returned me a message saying something about restarting the notebook So I rebooted the notebook and now OS X no longer starts, I executed in verbose mode and, after showing those monstes of plus signs (++++++++++++++++++++++) ++++++++++++++++++), it restarts... 1 Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted April 11, 2017 Moderators Share Posted April 11, 2017 You didn't post the output after running the commands so I have no idea what's going on with the permission and cache. Boot with the USB installer and then select the installed drive. Link to comment Share on other sites More sharing options...

Administrators Hervé Posted April 11, 2017 Administrators Share Posted April 11, 2017 If/when the kextcache command returns such an error "xxxxxxxx 77", repeat the touch + kextcache commands. You can ignore any other error but 77. Link to comment Share on other sites More sharing options...
