You can probably get away allocating less than 30GB to Windows 7, but it will leave very little room to install anything in Windows. Anything newer means you have to use Windows 10. If you’re using an older version of OS X (macOS High Sierra version 10.13 and earlier) you can still install Windows 7. Boot Camp no longer supports Windows 7 and only works with a 64-bit version of Windows 10 Home edition or Windows 10 Professional edition. This guide will take you each and every step of the way through setting up and installing Windows 7 on your Mac using Boot Camp.Ģ021 Update: this is a bit more complicated now.
