# Installs the AI Hub as a macOS menu-bar app: ~/Applications/AI Hub.app.
#
#   bash tools/aihub/install-mac.sh          (from anywhere; it finds the repository by its own path)
#
# 1. cargo build --release -p makepad-app-aihub (the native build, this Mac's default features),
# 2. assembles "AI Hub.app" under target/aihub-install/: Contents/MacOS/makepad-app-aihub,
#    Info.plist (nl.makepad.aihub, LSUIElement: a menu-bar app, no Dock icon, no menu bar),
#    icon.icns made from apps/aihub/resources/icon_1024.png with the system's sips + iconutil,
# 3. ad-hoc signs it with the stable identifier nl.makepad.aihub,
# 4. stops the installed copy (by the pid it recorded in ~/.makepad/ai-hub/app.pid, and only
#    when that pid really runs the installed executable), replaces ~/Applications/AI Hub.app,
# 5. prints how to start it.
#
# The AI Hub reads the Claude login from the keychain like the headless hub always did; macOS
# may ask once to allow it for this new program (click "Always Allow").
