I'm away from home this week, I'll try next week and keep you update thanks

I had to select manually "Macintosh HD" in OC screen on the first reboot ;)

Your mobo needs NVRAM support for a fresh install. Does your have it ? FYI @TheBloke invented a method (in this thread) to install on Unsupported NVRAM Mobos ;)

I vote for Opt. 2. Keep the more powerful GPU and you bought with the correct price!

Hello Thank you !! How did you modified the BIOS ? I'm interested Correct me if I'm wrong : with your custom SSDTs you can skip Lilu.kext ? if you can manage to your the built-in bluetooth, I want to know ;) What about the support of the NVRAM ? can you use Startup disk Prefpan natively ?

many thanks
