If you still have a copy of "Install macOS Sierra.app" on any of your Macs, you can simply copy that or make a bootable installer from it: sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ macOS\ Sierra.app
If you can't locate a copy of Sierra, please let me know and I'll mail you a USB installer. |
