# PowerLab macOS dev-mode installer.
#
# Usage:
#   curl -fsSL https://raw.githubusercontent.com/neochaotic/powerlab/main/install-mac.sh | bash
#
# What it does:
#   1. Verifies you're on macOS with Apple Silicon.
#   2. Checks prerequisites (Homebrew, git, go, node, Docker).
#   3. Clones the PowerLab repo to ~/Documents/powerlab (or PWLAB_HOME).
#   4. Hands off to ./dev.sh — the standard developer entry point.
#
# Why "dev mode"? PowerLab in production is a Linux-only systemd panel.
# On macOS we run the same SvelteKit + Go stack via `dev.sh` so you can
# use the panel locally for development, demos, or experimentation —
# but the file manager (which depends on Linux fuse + xattr) is disabled,
# and there is no auto-start at boot. For a real production install,
# point a Pi or mini-PC at install.sh.
