erase-install.sh
==============================================================================
by Graham Pugh
WARNING. This is a self-destruct script. Do not try it out on your own device!
See README.md and the GitHub repo's Wiki for details on use.
It is recommended to use the package installer of this script. It contains
swiftDialog and mist, which are required for most of the use-cases of this script.
This script can, however, also be run standalone.
It will download and install swiftDialog if needed and not found.
It will also download mist if it is not found.
Suppress the downloads with the --no-curl option.
Requirements:
- macOS 11+ (for use on older versions of macOS, download version 27.3 of erase-install.sh)
- Device file system is APFS
