Bootable USB Installer for older macOS versions on Apple Silicon
Sometimes it is necessary that you want to install an older version of macOS and therefore need a bootable USB flash drive. If you use a recent Mac with Apple Silicon CPU, this can be a bit tricky, because the disk images offered by Apple for the versions from Lion to Sierra contain an installer that you would first have to run to create a bootable USB installer with the well-known command ‘createinstallmedia‘. However, exactly this installer does not run Apple Silicon. Anyway, for versions from Lion to Sierra, there is a simple solution.
