I accidentally DELETED my "EFI" partition after uninstalling the Bootcamp Partition…. Now it won't let me update my 1.8 Firmware and OSX!! HELP PLEASE
I have a macbook 15 inch 2012 mid, i tried Windows bootcamp and decided i didn't really like it. So i turned back to MAC, and in DiskUtil i erased the Bootcamp partitions, and accidently deleted the EFI Partition that had like only 27 mb on it. I didn't think it was notthing but i did some more research on it....
MacBook Pro, MBP91.00D3. Pro Mid 2012, 15 inch.
