I am an IT director at a small Ace Hardware store located in a small town in Pennsylvania. We use Boot Camp to run Windows on Macs. We do not use Mac OS X, in fact I only install Windows When we get them. as Mac OS X is Completely open to prying eyes and a huge security risk. Apple's early EFI implementation was only compatible with EFI 1.1X and Apple has no intention of updating this firmware. Windows 8's UEFI implementation requires UEFI 2.X making them already incompatible, as well as apple's EFI not being able to load 64-Bit .efi files. We are planning on upgrading to Windows 8.1 Enterprise 64-Bit as all of our computers are capable of running this as they all have Core 2 Duo or better processors. We have Many iMacs, a few Mac minis and a MacBook used to solve problems on the go Most of which suffer from the problem of being old ( Apple only officially supports 10.7 Lion on these Devices ) We Have newer Completely Uni-body iMacs that are capable of UEFI 2.x and work just fine with windows 8's UEFI implementation. How possible would it be to flash a modded Firmware to one of these devices that would support UEFI 2.x? Most bios modding tools are able to dump it and read the modules contained inside it.
