I have found this topic to be very helpfull, thank you for that! I have follow the D630 guide to create an installer and installed sierra succesfully, i did use the "Extra" folder that griftopia posted. I have almost fixed all issues exept for the fact that the CPU is running on one core.
About this mac displays that i am running a core 2 solo, and the total amount of cores is 1, how did you fix this?
MBP version is 7,1
CPU is a T9800, (will be upgrading to a X9100)
4GB of RAM
NVS 160M
