    Hi,

    I have a MacBook Pro 13" 2014 EMC 2875 which just chimes and then restarts. I've tried about 6/7 different EFI's but not able to make it work properly. The closest i have go to is for it to start but it gets stuck on the Apple logo.

    Can someone fix the attached EFI please.

    Thanks

    The original bin file when the eDP is connected it chimes restarts, chime restarts continuously. Without eDP chimes ok but of course no display.

    I have tried another EFI file (working but hangs.bin) and it boots ok with eDP connected but logo hangs.
