Hello,

 

I accidentally deleted applehpet.kext from my 2009 mbp running mavericks.  So far, I have booted from a Mavericks USB stick and opened Terminal.

 

I would like to know what commands are necessary to copy the kext file from my usb drive and paste into S/L/E.

 

Additionally, if there are repair disk/utility permissions needed please include those.

 

Thanks in advance.

Hi,

First you have to mount hdd with read and write access.

 

mount -u -w /Volumes/namehdd

 

You will find terminal command for that, when you launch terminal from USB pen.

 

Second you have to copy kext:

 

 

cp /Volumes/nameUsb/System/Library/Extentions/name kext.kext /Volumes/nameHdd/S/L/E ...

 

Then

 

touch /Volumes/nameHdd/S/L/E

 

Reboot

 

naturally instead of S/L/E you should use /System/Library/Extentions
