I could install Steam and get to work in Grand Theft Auto or Battlefield, or run Office or any Windows-only application that I like. There can be a few oddities – the trackpad functions far less well in Windows and Wi-Fi failed to work until I found the relevant drivers on Apple's Help site – but for all intents and purposes my MacBook is now a dual-booting PC, running the best of Microsoft and Apple. When booted, the Mac behaves like a Windows PC – it becomes, in effect, a Windows PC. Once I had this sussed, I restarted my Mac, held down the 'alt' key (from where I assumed the Mac had switched off, although I'm not sure how accurate you need to be within the Restart), selected the drive entitled 'Windows' and my copy of Windows 8.1 booted up perfectly, even speedily. Windows 8.1 boots up quickly Speedy Windows
