#
# What it does, in order:
#   1. Checks you have an Apple silicon Mac with macOS 13 or later.
#   2. Downloads the app's .zip from its GitHub Releases page (github.com/lidworks/<app>) into a temporary folder.
#   3. Puts the app in /Applications (or ~/Applications if you can't write there), replacing an older copy.
#   4. Opens it. The app then walks you through anything it needs.
# It asks for no password and changes no settings. Files downloaded by Terminal aren't marked
# "from the internet", so macOS opens the app without the "Apple could not verify" prompt.
# To remove an app later: quit it from its menu, then drag it from Applications to the Trash.
