Works to erase Macs running macOS versions v10.13 High Sierra and newer and up to macOS v11.x Big Sur.
Uses erase-install.sh --update to fetch latest macOS version to install with rather than keeping the same major version using --sameOS.
Includes release 0.19.0 of erase-install.sh. For Silicon Macs, this version ensures the authorising account for startosinstall --eraseinstall is admin. Also running diskutil apfs updatePreboot for Silicon Macs is handled there instead of in the auto-erase-install wrapper script.
Building customised / forked versions is made easier with the automated build.zsh script, now in its first working version.
