So I thought everything was fine,. But after doing kext repair/permissions I boot with or with out -v. It starts to boot then the screen dims and goes black and it does the same thing when booting from the USB drive,. I can only boot back to the installer

 

I can boot into safe mode but not sure what to do,. I thought it was a text but that doesn't seem to be the case. I have reinstalled about 5 time trying different things but as soon as I do kext repair the system fades to black.

DW1560 is M.2 connection. You need DW1550

Have you tried connecting to an external monitor?

What version of Bios are you on?

Perhaps try exporting a DSDT/SSDT for patching.

 

For now, try booting without the DSDT, see if it makes a difference.
