# angel — one-line installer for mac. removes the gatekeeper friction
# of an unsigned alpha build by clearing the quarantine bit after copy.
#
# usage:
#   curl -sSL https://angel.stephenhung.me/install.sh | bash
#
# what it does:
#   1. downloads the latest .dmg from github releases (arm64 only)
#   2. mounts the disk image with hdiutil
#   3. copies Angel.app into /Applications (replacing any existing copy)
#   4. removes the com.apple.quarantine xattr so first-launch doesn't bounce
#   5. ejects the dmg + cleans up
#   6. opens the app
#
# tested on macOS 14+ apple silicon. intel mac + windows builds coming soon.
