BootChamp is an macOS menu bar app that makes it easy to boot into your Boot Camp Windows partition. Instead of using Startup Disk in System Preferences or holding down the Option key at startup, just select "Restart into Windows" and BootChamp will do the rest.
This software requires macOS's System Integrity Protection to be disabled. Disabling SIP makes your system more vulnerable in terms of security. If you want to use this software regardless of security problems, USE THIS SOFTWARE AT YOUR OWN RISK.
There are still many people using old MacPro(a.k.a. tower mac) like me. The problem is that if you install third-party GPU on a tower mac, you cannot see EFI screen when the system is booting. It means that you cannot use startup manager to select which OS to boot. To make the problem worse, Apple's Bootcamp driver doesn't recognize APFS partition so if you want to boot to macOS again, you need to enter recovery mode and then select macOS partition as boot device. That's why I needed a way to temporarily set what OS to boot. I found this application and added "hotkey" support so I can reboot the system into bootcamp with just a shortcut input. But still, I don't recommend using this software since you have to disable SIP.
