I start with 10.10, then update to 10.10.1 from AppStore
Use multi beast 7.1.1 for boot and System Definition 8.1
Install from USB, copy extra to HDD
Use multi beast to install Bootloader and System Definition
Bootloaders -> chimer
Customise -> System Definitions -> MacBook Pro 8,1
Build -> Select Install Drive -> Install
reboot -> Disk Utility -> repair disk permissions -> restart -> repair again disk permissions -> restart
Today i tested D630 nVidia, but 2,1GHz cpu. EDP can not download kexts . I use same EXTRA, but on HDD with System Definition 5.1.
