You will have to unplug and plug the USB cable back in after each reboot in order for apcupsd to be able to connect to the UPS. To load apcupsd at startup, activate the included Launch Daemon: sudo cp $HOMEBREW_CELLAR/apcupsd/3.14.14/lib/Library/LaunchDaemons/org.apcupsd.apcupsd.plist /Library/LaunchDaemons sudo chmod 644 /Library/LaunchDaemons/org.apcupsd.apcupsd.plist sudo launchctl load -w /Library/LaunchDaemons/org.apcupsd.apcupsd.plist If this is an upgrade and you already have the Launch Daemon loaded, you have to unload the Launch Daemon before reinstalling it: sudo launchctl unload -w /Library/LaunchDaemons/org.apcupsd.apcupsd.plist sudo rm /Library/LaunchDaemons/org.apcupsd.apcupsd.plist - Bottle: available on arm64_big_sur, arm64_linux, arm64_monterey, arm64_sequoia, arm64_sonoma, arm64_tahoe, arm64_ventura, big_sur, catalina, monterey, sonoma, ventura ## Freshness - Page generated: 2026-07-08 - Package-manager version: 3.14.14 - Local data: ok - Upstream repository: http://www.apcupsd.org - info: No package-manager update timestamp was available. - info: Release/tag comparison is only available for GitHub repositories. ## Project history and usage apcupsd is a daemon and command-line toolset for monitoring and controlling APC UPS devices. It is one of those infrastructure packages that quietly matters because it can shut systems down cleanly when power fails. ### Project history The apcupsd project dates to the long-running Unix tradition of hardware daemons: small background services that translate a device protocol into system policy. Its official manual documents operation with APC UPS hardware, configuration through `apcupsd.conf`, status querying through `apcaccess`, and testing through `apctest`. The project has historically lived on SourceForge, with source control exposed through the official SourceForge project tree. That hosting history matches many mature system utilities that predate GitHub-centered development. ### Adoption history apcupsd's adoption is strongest in server, NAS, homelab, and workstation environments where APC UPS hardware is common and a lightweight local daemon is preferable to a larger management suite. The supplied package data shows broad Unix-like packaging: Alpine, Homebrew, Debian, Fedora/dnf, MacPorts, Nix, Arch/pacman, Ubuntu, and openSUSE/zypper. That breadth is the package-history signal: administrators expect it to be available from the native package manager on almost any Unix-like system. ### How it is used Typical usage is to configure `/etc/apcupsd/apcupsd.conf`, run the `apcupsd` daemon, inspect UPS state with `apcaccess`, and test device communication with `apctest`. Scripts and service managers then use the daemon's events to perform clean shutdowns or notifications. The package is hardware-facing, so installation alone is not the whole story. Correct cable/device selection, daemon privileges, and shutdown policy matter more than application-level credentials. ### Why package nerds care apcupsd is package-nerd significant because it represents the unglamorous layer where packaging meets physical infrastructure. A good package has to install a daemon, config file, service integration, helper commands, and documentation without hiding the hardware-specific knobs. It also illustrates why old system packages remain valuable: power events are rare, but when they happen the daemon must already be installed, configured, and boringly reliable. ### Timeline - 1990s: apcupsd emerges as a Unix daemon for APC UPS management. - 2000s: SourceForge hosting and distribution packaging make apcupsd a standard sysadmin utility. - 2010s: Linux, BSD, and macOS package ecosystems continue shipping apcupsd. - 2020s: The package remains available across mainstream Unix-like package managers. ### Related projects - Network UPS Tools is the most common neighboring UPS-monitoring project. - System service managers and shutdown tools are operationally adjacent because apcupsd's main job is to react safely to power events. ### Sources - - - source_facts.executables - source_facts.package-manager ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials.
