DTGP is a basic patch you have to add to the DSDT, maniac. In the DSDTEditor.app patches folder (it comes with the app), there's a DTGP.txt. Just go to the menu patch, select open, browse until find the DTGP.txt and apply it. :)

Thank you...


Now I have following errors:


_HID suffix must be all hex digits




Name already exists in scope (_PRW)


Could you please help me with that?

Use the "fix errors" from the DSDTE.app. The first error - hex digits - you can solve just deleting the line. the second is a distinct indication you did something wrong and maybe should start over.
