Hi everyone,
I have a really particular problem
I’m using a macpro 5,1 being a triple boot : Mojave, mountain lion, windows 10
each on their own ssd
At the beginning, during my tests, everything was working fine
Since I used the startup function on the os’s, I lost the ability to start the computer with the option key engaged in order to change the startup os… if I do it, the computer freezes
So my main goal is to still have my triple boot system, with the ability to choose my os at the startup.
I don’t want to upgrade the os (at least for now) just use my setup and be able to switch to one os to another without hassle
So please forgive my candid question but is it possible to achieve that with open core, without having to completely reinstall everything and have the startup screen of open core at every power up of the computer ?
if yes, how do I do it ?
Many thanks for your answers
