Commit Message Guidelines

Short (72 chars or less) summary

More detailed explanatory text. Wrap it to 72 characters. The blank
line separating the summary from the body is critical (unless you omit
the body entirely).

Write your commit message in the imperative: "Fix bug" and not "Fixed
bug" or "Fixes bug." This convention matches up with commit messages

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/ .
