what it's strange is I still got a ioreg.txt containing some hex data. I ran the modifiers in the shell script then the DSDT patcher dsdt.dat and it seemed to patched it. I'll try the generating DSDT or the ubuntu way, luckily I got one installed.

But the strangest is I couldn't kill the ioreg process, sudo killall -9 ioreg, sudo kill -9 pid, or using the activity monitor, nothing...

Edit: the ioreg generated file was wrong, the fixed files contains strange characters, but nothing like what it's supposed to have... I try other ways and keep you informed
