I currently have Sierra + Windows on separate SSD drives since 2016. What would be the process for installing Mojave on a third internal SSD. I tried installing mojave to an external SSD but I could not finish the install process as the bootloader does not show the Mojave SSD after restarting even though it seemed to be installing and I believe the EFI for the Mojave SSD is empty after mounting it on Sierra. Tried this method on other macbook and mojave installed on the external SSD & booted. What gives.
