This is a set of Packer templates and support scripts that will prepare an OS X installer media that performs an unattended install for use with Packer and VeeWee. These were originally developed for VeeWee, but support for the VeeWee template has not been maintained since Packer’s release and so it is only provided for historical purposes. I plan on removing VeeWee support from this repo soon, but VeeWee can still make use of the preparation script and the OS X template remains in the core VeeWee repo.
