Hello. I need a little help. I am presently running MacOS Sierra fine together with an Ubuntu installation on this system. The main OS for the system is Ubuntu, but Sierra is installed on a secondary partition and I use an old UniBeast High Sierra Installer USB that I had created when I thought to upgrade to High Sierra to boot up the MacOS. I am trying to upgrade MacOS to Catalina. I have successfully downloaded the "Install Catalina" app. I have downloaded UniBeast and MultiBeast for Catalina. I created the Catalina Install USB by using DiskUtils to erase a newly purchased 64BG USB Drive and then running UniBeast. I used the Legacy boot option because I have an old system, but for some reason, the USB does not boot. I must admit, I don't quite know what I am doing. All I would like to do at this point is to be able to create the installer USB and see that it does boot on this system. The rest I will try to resolve as I go. Can anyone help me to at least create a functioning bootable installer USB? I would really appreciate it. I really need to upgrade this system at this time.
