Hi i have a problem with my mac
I just use a bootable Unibeast usb with sierra installation to my mac retina
I press alt and i boot from usb to installation menu and i just waiting to load the bar all good until
nothing happens then i just press off to close the mac from then until now nothing happens
The mac just opens in black back light no boot no sound no reseting no clearing nothing
I just made everything remove battery 24 hours remove ssd no boot
I thing that 90% the usb stick it goes to efi bios on my mac and write on it and destroy it
can anyone have any other option to make it back in life?

If you ask me why i load the usb to my mac the answer was because i didn't have and other machine to check if that usb works ok i have also a damaged z77 ud5h that it makes strange things so i choose to test it on my mac

I also search on ebay find many efi bios chip to replace them on my mac retina any other solution?
 
Thanks but i work on this all Resets over 2 days doing nothing just open the back light stay there four 5-10 minutes pressed all reset commands that i find on the net and then close back light with on off button
I thing the only button that is still working is on off no other keyboard keys are working also i take everything out of the case ssd battery wifi keyboard lcd all adapters leave it out on the dest 24 hours reconnect everything no working even with out ssd no booting even with out lcd no working even with out all the assessors wifi or ssd no working same this opens back light close back light i work about a week before posting .....

Try the Apple support forums - This site is for PC hardware not Mac.
 
i know that but the same will answer to the other site because i thing that someone from here will know what the Unibeast can do on pc? what files has to change the efi bios on a real mac !!
Also i make that to protect in the future someone not to try it at home on any mac computer !!
And as i searching on internet none has done that so i am the first !!!!! and it is so simple to put this usb on a mac computer and test it so WARNING!!!!
