I have recently installed Boot Runner and purchased a single license. I’ve been running into an issue where after selecting Windows in Boot Runner, it will always boot into Windows from then on, as if it has changed the default boot drive, until I reset the NVRAM to force the mac to boot back into macOS.
I have a Mac Pro 5,1 and use an SSD in for macOS High Sierra (APFS), and a HDD for Windows 10, both in SATA bays.
I believe I have installed everything correctly, but I’ll summarise my installation for you.
Installed the Boot Runner package, installed license, selected my Mac SSD as the default boot drive in System Preferences, ensured Auto Login was disabled, restarted in Recovery Mode and used terminal to execute " csrutil enable --without nvram " (note that I needed to use the " – " trick to return anything, a single " - " did not work).
Boot Runner then works beautifully to boot into macOS, and at first it works to boot into Windows. But when I either restart or shut down from Windows, it automatically boots back into Windows again! This kind of defeats the purpose of Boot Runner, as I then have to reset my NVRAM once again to get back into macOS, meaning I also have to disable SIP agian with the terminal command in Recovery Mode etc etc. and it all just takes ages to get it working again.
Could there be something I’m missing in the initial setup? Any advice would be greatly appreciated, as at this point I’d frankly find it easier to boot into windows using the macOS system prefs, and then boot back into macOS using NVRAM reset - it’s currently less work than the long workaround for Boot Runner’s quirk I’ve encountered.
