Thank you sir, it worked !!
My screen is normal, not split again.
But, i get freeze on my start up when i boot from hard disk.
So, i follow the instruction which said to entry on single user mode (-s) and then move IntelHD kext to Backup folder.
It was succes to bring me entry the graphical environment.
But i am confused on changing SMBIOS.plist.
On my mac, it said if my mac is "imac"
I try to change it to MacBookPro8.1 using chameleon wizard,
Chameleon wizard said there is no SMBIOS.plist, so i generate one and save it on Document folder.
But, it not change my mac from imac to macbookpro..
I try to make Extra Folder on system, and put it there, but it also not work..
What i must do next?
Where i must put the SMBIOS.plist to make it work??
