How To Restore or Reinstall Firmware for Macbookpro11,1?
I have a MacBook Pro 11,1 and wish to restore and/or re-install a fresh copy of the firmware. There used to be a Restoration CD to do this, but one has not been publish by Apple since Macbookpro5,1.
Any help in understanding how to do this?
Thank you
