Sierra Update Broke my Hackintosh

Recommended Posts

DENY MACH-LOOKUP SANDBOX Errors after Sierra Update

I was using Niresh Yosemite for a while, then i installed the Sierra update from appStore.

Now my boot loader keeps locking up in a loading screen.

When i try verbose, i get a loop of errors about Denied Permission on loading new kexts.

i did try teh solutions from this link: https://www.hackintosh.computer/89/sandbox-error-niresh-yosemite/ but when i try any of these commands 

sudo sed -i.bak 's/1.2/1.3/g' /usr/standalone/bootcaches.plist
sudo sed -i.bak 's/lzss/lzvn/g' /usr/standalone/bootcaches.plist

the terminal cant locate the 's/1.2/1.3/g' or the 's/lzss/lzvn/g' directories
It's probably because the solution is focused on Yosemite directories.

Is there any way to repair the kexts permissions, or adapt this fix on the Sierra?

thanks in advance

I don't know if this would help but I was in similar situation,  I was on 10.12.3.  and updated to 10.12.4.  then my Hackintosh wouldn't load after loading screen reached half way, (it'd restart/black screen/monitor off)   as I had USB stick already loaded with clover installation. I read on forums to edit config.plist  located in clover partition on usb stick with this code  (which I did on windows using notepad)


<string>Kext Injection allowed</string>


then used that config to boot into  Sierra installation on hard disk and it booted.

i'll try this solution. 

The problem i have is that the OS tries to load itself, 
then the mouse cursor appears on the screen for some seconds.
And lastly it comes back to the loading spinning wheel screen.

as i told before, verbose shows these errors in a loop:
