Hi Sorry to ask, but I have been working 4 days to fix my macbook pro. I actually erased my drive to make it new. what was left was the new drive and the recovery. When reinstalling a new copy of os x it just let me login my apple id and says my apple id is used in US then redirected then nothing is happening. I tried also to make a bootable usb using transmac note that it is also gpt already and still nothing happens because my macbook does not see my bootable usb upon booting by holding the option key.
