Today i installed Maverick with the same Method,used the Maverick Bootpack.I delete all ATI,AMD,Geforce and Nvidia Kexts,and every Kext i install from Raven i also delete in S/L/E. First time boot i unplugged all USB from Laptop,boot im SafeMode and use Chamäleon Wizard to fix USB.Now it works Perfekt.Copied the DSDT.aml from Ravens Pack in Extra Folder
