Well, I have Catalina installed, but I have few USB issues. I decided to try a fresh install on a fresh SSD following this sites guide on Mojave using my new AMD Mac.
However, I am stuck here on this section of the guide:-
kb.amd-osx.com
[email protected] /Volumes % diskutil mount /dev/disk4s1
Volume EFI on /dev/disk4s1 mounted
cd: no such file or directory: /Volumes/OS X Base System/System/Library
[email protected] /Volumes % cd /Volumes/OS\ X\ Base\ System/System/Library
Where xxx is my name.
