A menu bar app for macOS
Keep your agents awake
Caffeinum keeps your Mac awake and sets the daily wake and sleep schedule. It does nothing else.
macOS 13 or later, Apple silicon
Or install with Homebrew
$ brew trust vojtechmares/tap$ brew install --cask vojtechmares/tap/caffeinumWhat it does
A thin, honest front end to two macOS tools
Keep-awake is a supervised caffeinate(8) process. The schedule is a
pmset(1) repeat power event. The flags Caffeinum passes are shown right in the UI.
-
One switch
Starts and stops caffeinate, the tool macOS already ships for preventing sleep. Four checkboxes map straight onto its flags. Run it indefinitely, for 15 minutes up to 5 hours, or until a time you pick - the time left shows next to the menu bar icon.
-
Daily schedule
Pick wake and sleep times and the days they apply on. Caffeinum turns them into a single pmset repeat power event. The schedule lives in the system, so it keeps working when the app is not running and survives a reboot.
-
Fails safe
caffeinate is started with -w and Caffeinum's process ID. If the app is force quit or crashes, the assertions are released instead of leaving your Mac awake forever.
-
Stays out of the way
Everything lives in one panel behind the menu bar icon. Launch at login, restore keep awake on launch, and a global shortcut (⌃⌥⌘C by default) that needs no Accessibility permission. No privileged helper stays installed - the admin password is asked for only when you change the schedule.
Try it
Every flag is on screen
No hidden magic. Tick a box and watch the exact command Caffeinum runs. With every box unchecked it falls back to
-i, which is what a bare caffeinate does anyway.
Pick wake and sleep times and days, and see the one pmset repeat event they become.
macOS only lets root set power events, so Caffeinum asks for permission at the moment you press
Apply schedule.
This is a demo of the real flags. Nothing runs on your Mac.

Good to know
- Apple silicon only. Intel Macs are not supported.
- macOS supports exactly one repeating wake event and one repeating sleep event system-wide, so applying a schedule replaces whatever was there - including one set in System Settings > Battery > Schedule.
- Builds are ad-hoc signed but not notarised, so the first launch of a zip downloaded from GitHub needs the usual right-click, Open. The Homebrew cask clears the quarantine flag for you.
