Due to the requirement to have a Metal compatible graphics card to install Mojave, many users upgraded their graphics cards to PC cards that do not have EFI firmware and therefore cannot display the Startup Manager (also known as Boot Screen).
Many Mac Pro users usually install Windows in dual boot using Boot Camp or in EFI mode, and even some install even Linux. Due to the lack of boot screen, it is very difficult to switch between operating systems, although there is the possibility of using "Startup Disk" from "System Preferences", but does not always work well (usually does not work with Windows installed in EFI mode) or does not detect all operating systems correctly (as is usually the case with Linux).
There are other options and alternatives to the "Startup Disk" option, such as BootChamp and QuickBoot, however both applications are discontinued, without support, updates and hardly work in new versions of macOS.
Boot Manager is an alternative to all the options described above, is completely free, is open source and works with the latest versions of macOS. Boot Manager is an application based on QuickBoot, with updated code to run on recent versions of macOS and with major improvements over its predecessor, including support for Windows, macOS and Linux in both BIOS (Legacy) and EFI mode.
