Actually… It depends on what you want your USB installer to do. If you want a bootable USB installer then you need to use one of the applications that will make a bootable one or use the technique available on the web to use the makeinstallmedia command from terminal. If you just want to put the installer itself on the USB drive, stick it into another Mac booted from it’s internal drive and use the installer on the USB to do an in-place upgrade…that will also work; doesn’t need to be a bootable USB for that.
I’ve done it both ways over the years…albeit not with High Sierra. > On Nov 11, 2017, at 11:06 PM, Carl Hoefs <[email protected]> > wrote: > > >> kay, I guess I was given bum advice.
