hi bro i got same model e6410, and got the lion 10.7.4 running perfect, but by following your guide after install finished it says ' install failed '
reboot anyway, by using -v model, the system stuck at ' pci configuration begin', replace with my 10.7.4 kext (applecpiplatform.kext, ioacpifamily.kext, iopcifamily.kext) but still failed, any idea ?
