Create bootable USB installer
I'm following this guide here and after entering the Terminal command, at step 6 it asks me this question:
"To continue we need to erase the disk at /Volumes/Macintosh HD."
"If you wish to continue type (Y) then press return:"
Does that mean that it will erase the current disk that I'm using on the current computer? because that's not what I want.
