I need some help, it stuck when i get the install screen all i get is a grid screen, i can install mac with UB and everything is fine except a few problem with device like sound, centrino wireless card etc. i wouldn't be fine until i can accomplish this excellent guide. I'm trying to do an internal HDD installation i attached a pic with the grid screen.
if you are new for this community, and find a good result for your laptop, there are many stuff you need to know. For installing, i recommend you use chameleon to do it with internal hdd installing method, hd3000 GPU needs to set SMBIOS to MBP8.1 that you can find out in the first post attachment.
Wireless card isn't compatible with MAC OS, u need to replace with another like BCM43XX or BCM943225HMB( if you can buy this) is a good choice.
Other devices like sound, ethernet, camera, USB3.0(if you have) you can search forum.
