Good evening,
I'm following this procedure from nikey22, but I can't figure out how to load the ROM onto my GPU.
How do I edit AppleBacklight.kext?
I'm installing the GPU on a 2011 iMac.
I've already replaced the CPU with an i7 2700k 3.5 GHz, 32 GB of RAM.
I just purchased a Nivida k4100M
4 GB, but I need your help installing it.
Thanks.
Sorry for the translation, I'm Italian.
