Hi there.

I tried to install Sonoma in my MacPro 5. These are what I wrote in Terminal:

diskutil list
diskutil mount disk(+disk name from the list)
bless --mount /Volumes/EFI --setBoot --file /Volumes/EFI/System/Library/CoreServices/boot.efi

I think it was ok. These codes were mentioned in dortania.github site with Sonoma installation.

Installation kind of went fine, until it stuck in error with Update Assistance tool.

I had two OS's installed in separate disks, High Sierra and Mojave, I erased one with HS and decided to try install Sonoma in it.
Now I can't boot in Mojave, only option is Sonoma installations two choices which stuck both.
I would like to return in previous state somehow, what to write in Terminal to cancel what I wrote before?

I'm sorry but I don't handle or understand this code almost at all to actually know what I'm doing, but I'm willing to try learn something and would appreciate very much your help with this.

And which newer OS you would prefer for this MacPro, with better results?
