Warning!: Since I wrote this article it has been discovered that Windows when installed in EFI mode is corrupting the Mac Pro’s firmware by signing it with multiple x509 certificates. However, it appears the firmware is being corrupted when Windows is installed in legacy mode as well since at least one user has reported a bricked machine. Therefore it is not recommended to install Windows on the Mac Pro! No boot screen? No problem. There are a few nifty programs that allow you to dual boot Windows and MacOS easily. There's a free one called BootChamp by Kevin Wojniak. It's a simple program that places a Windows icon on the menu bar. To boot Windows simply click the icon and then select Restart into Windows. There's another one called QuickBoot that is like a mini Startup Disk preference pane that also works from the menu bar like BootChamp. It gives you control over your macOS startup disks in addition to your Boot Camp disk. Then there is a paid program called Boot Runner by Twocanoes. It basically does the same thing as BootChamp but instead of placing an icon on the menu bar it gives you a fancy customizable boot menu that overlays the login screen. It has advanced options and is useful if you have multiple OS installations including Linux. These programs make a temporary change in NVRAM to select the startup disk so that part of System Integrety Protection must be disabled. To do that start your computer in Recovery Mode by holding command + R at startup. Open Terminal from the Utilities menu and type “csrutil enable --without nvram” and then restart the computer. BootChamp can be downloaded from https://www.kainjow.com/. QuickBoot can be downloaded from https://buttered-cat.com/product/quickboot/. Boot Runner can be found at https://twocanoes.com/products/mac/boot-runner/. There is a 14-day free trial available to new users.
