you don't need to reinstall, just install your kexts properly in the proper location

should not be installed:
DirectHW.kext
HoRNDIS.kext

should not be patched:
AppleMobileDevice.kext
AppleGraphicsDevicePolicy.kext

No other suggestions for you then.

Seems likely your AppleHDA.kext is damaged, perhaps other system kexts/system files.

as my wifi intel 3160 drivers are not available i use this for usb tethering!

You might eliminate it during testing.
Use Ethernet.
Or install supported WiFi hardware as recommended in the FAQ.

should i delete this from S/L/E?
Click to expand...

No.
Restore to vanilla by running the macOS installer.
 
krishnapal said:
if i re-run the installer will my data be gone??
Click to expand...

No.
As long as you don't erase the partition prior to running the installer, the installer will simply refresh all system binaries.

But you should have a backup of your data for the case of human or other error.
Or for hardware failure.
