Shutdown provides an automated shutdown procedure for super-users to nicely notify users when the system is shutting down, saving them from system administrators, hackers, and gurus, who would otherwise not bother with such niceties.
How to configure native shutdown of Mac OS X Product Line/s: Smart-UPS Back-UPS Environment: Mac OS X attached to UPS via USB cable NOTE: According to Apple, Energy Saver options are not available for UPS on portable devices e.g. MacBook, MacBook Pro, MacBook Air. See Apple discussion thread 8398176. Cause: Installation information Solution. Few days ago I published on github a configuration/script able to be executed at boot/shutdown. Basically on Mac OS X you could/should use a System wide and per-user daemon/agent configuration file (plist) in conjunction with a bash script.
When a Mac starts up (including following a restart) or wakes from sleep, the reason for the previous shutdown (or initiation of a restart) or sleep is reported in the log. Unfortunately, Apple considers these reasons to be of no concern to the user or system administrator, so they are given as numbers, and Apple does not release information on. Turning off the power without shutting down your Mac properly is one of the worst things you can do to your poor Mac. Shutting down your Mac improperly can really screw up your hard or solid-state drive, scramble the contents of your most important files, or both. At shutdown time a message is written in the system log, containing the time of shutdown, who initiated the shutdown and the reason. A terminate signal is then sent to launchd to bring the system down to single-user state (depending on above options). A scheduled shutdown can be canceled by killing the shutdown process (a SIGTERM should suffice).
At intervals, becoming more frequent as apocalypse approaches and starting at ten hours before shutdown, warning messages are displayed on the terminals of all users logged in.
