- 2012 and older models only support legacy BIOS Mode. There is varying degree of 'EFI'ness in these, but they are not UEFI-compliant.
- Late 2013-2014 models support both EFI and BIOS, and default is BIOS. These are the first models which are UEFI.
- 2015 and later models only support EFI and UEFI-compliant.
Exe On Mac Osx
Apr 18, 2020 Is it possible to install Windows on entire Mac Air's SSD? I am switching to Windows and every MB of space is important for me. If it is possible, does it go like this? Installing Windows using BootCamp. Using Disk Utility in Windows 10 to remove MacOS partition and reallocating the space for Windows partition. May 30, 2016 On rMBP 15' late 2013, however, you can't install Windows 7 from installation USB created by Boot Camp or Rufus because when you boot in non-EFI mode without Boot Camp Assistant help no input devices work so you end up with being unable to press Next.
BC Assistant knows all this. It is highly recommended that you use BC Assistant only, to install Windows on Macs. Using Alt/Option to interrupt the default installation process is not recommended, unless you know what you want.
On a 2012 MBP, you need to use BIOS mode, because CSM-BIOS exports the Cirrus devices correctly but EFI does not.
