# The baseline settings every new Mac starts from: Finder, Dock, keyboard,
# trackpad, menu-bar clock, Spotlight. Run it once, when setting a Mac up:
#
# ~/src/soarez/dot/macos-defaults.sh
#
# A private layer's bootstrap may run it on a new Mac; install.sh points to it
# otherwise. Nothing runs it on its own, and nothing should: it
# replaces the Dock with the three apps below and restarts Finder and the Dock.
# A Mac is free to drift from these afterwards; this is where it starts, not a
# state kept in sync. Asks for sudo, for the Spotlight setting.
