Unfortunately i do not have installed it from dosdudes patcher. I had 10.14.0 before i updated, because it was said somewhere, that it should be safe to install any further updates.
Plus, i do not have an usb installer no more, but I can create a new usb installer with my friends macbook, that would be no problem i think. But we can handle that by tomorrow, thats why i had some hope, if i could do anything else for now.
You need the patcher (USB drive) to fix your OS.
