                Notes on getting macOS Sierra running in Virtualbox on a Windows 10 host
              
          
    On Mac

Download, but don't run, the Sierra installer from the Mac App Store. This places the installer at
/Applications/Install\ macOS\ Sierra.app/.
Now run the following commands to build a suitable VM image from the installer:
git clone https://github.com/jonanh/osx-vm-templates
cd osx-vm-templates/packer

sudo ../prepare_iso/prepare_vdi.sh -D DISABLE_REMOTE_MANAGEMENT -o macOS_10.12.vdi /Applications/Install\ macOS\ Sierra.app/ .

  -h, --help     display this message
  -D, --decode   decodes input
  -b, --break    break encoded string into num character lines
  -i, --input    input file (default: "-" for stdin)

NOTES:

The PCRE engine (Perl Compatible Regular Expressions) is what BBEdit and TextWrangler use.

Items I'm unsure of are marked '# PCRE?'.  The list while fairly comprehensive is not complete.

# Rename the File if contain space
