Supported, but it’s completely possible though not quite easy.Īnother challenge is that macOS Mojave 10.14 now implies using Metal-capable GPU while most of them are not able toĭisplay Apple boot menu (which you normally see holding the Option key) required to boot into Windows. Installing Windows is no longer officially It’s prettyĭisappointing considering how capable and upgradable these machines still are. After that, reboot the computer into Windows 7 and install the Boot Camp software.Classic Mac Pro 5,1 (or simply cMP, also 4,1 upgraded to 5,1) is now considered by Apple as vintage. To make Windows 7 work properly, you'll need to boot into the Mac OS and copy the 'Windows Support' folder that was downloaded earlier onto a thumbdrive. Once the installation is done, you can boot into either of the OSes by holding down the Option key during the boot process. In my experience, it was superfast to install Windows 7 on the MacBook Air from an USB drive, taking just about seven minutes. You can easily fix this by making the installer reformat this partition. Windows 7, however, will not install on a FAT32 partition. Pick the option to boot of the USB thumbdrive.įrom now on, the installation is self-explanatory, except for just one little issue: the partition created by Boot Camp Assistant, named 'Boot Camp,' which is the partition you need to install Windows 7 on, is formatted in FAT32. You can move between the different options by using the arrow keys and pick one by pressing Enter. Here you will find the option to boot from the thumbdrive, which is represented by a Microsoft flag with a little icon of an external hard drive at its corner (see screenshot above). If you have done step B correctly, you will see a little photo of a hard drive with the letters 'rEFIt' underneath press Enter and you will be greeted with the all-new rEFIt start-up options.

As soon as the computer restarts, press and hold the Option key.

Now, insert the Windows 7 installation thumbdrive into the MacBook Air's USB port and restart the machine.
