# Installs Desk Link as a regular macOS app: ~/Applications/Desk Link.app (Dock icon, menu bar,
# can be kept in the Dock).
#
#   bash tools/desklink/install-mac.sh          (from anywhere; it finds the repository by its own path)
#
# 1. cargo build --release -p makepad-app-desklink (the native build, this Mac's default features),
# 2. assembles "Desk Link.app" under target/desklink-install/: Contents/MacOS/makepad-app-desklink,
#    Info.plist (nl.makepad.desklink, a regular app: no LSUIElement), icon.icns made from
#    apps/desklink/resources/icon_1024.png (rendered from icon.svg by tools/app_icons/render.sh)
#    with the system's sips + iconutil,
# 3. ad-hoc signs it with the stable identifier nl.makepad.desklink,
# 4. stops the installed copy (by the pid it recorded in ~/.makepad/desklink/app.pid, and only
#    when that pid really runs the installed executable), replaces ~/Applications/Desk Link.app,
# 5. prints how to start it.
#
# Opening the app again (Dock, Finder, open) brings the running one to the front; closing its
# window hides it and the app stays in the Dock, a click on the Dock icon shows it again; Cmd+Q quits.
