# What it does, in order:
#   1. Checks you have an Apple silicon Mac with macOS 13 or later.
#   2. Downloads LidworksLab.zip from our GitHub Releases page into a temporary folder.
#   3. Puts "LidworksLab.app" in /Applications (or ~/Applications if you can't write there),
#      replacing an older copy if there is one.
#   4. Opens it.
# 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 "can't verify the developer" prompt.
# To remove it later: use "Delete App and Quit" at the end of the test, or drag it to the Trash.
