# What it does, in order:
#   1. checks macOS (12 or later) and picks the right build: Apple silicon or Intel;
#   2. asks the Fiscoo website for the download link using your firm's personal code;
#   3. downloads Fiscoo and checks its SHA-256 fingerprint (if it doesn't match, it stops and installs nothing);
#   4. copies it to Applications (replacing an older version: your firm's data is not touched) and opens it.
# It doesn't ask for a password, doesn't use sudo and doesn't change any Mac settings. Downloaded this way, Fiscoo
# opens without the "Open Anyway" step in System Settings.
