Keyboard Shortcuts to Sleep Your Mac Instantly

Walking away from your Mac shouldn't require mousing up to the Apple menu. macOS has three distinct keyboard moves here — sleep the whole machine, sleep just the screens, or lock without sleeping anything — and knowing which is which saves both battery and interrupted downloads.

Sleep the whole Mac: Option+Cmd+Power

Press Option+Cmd+Power and the Mac goes to sleep immediately — same effect as choosing Apple menu → Sleep. On a MacBook, the power button is the Touch ID key in the top-right corner of the keyboard; on older keyboards with a media eject key, Option+Cmd+Media Eject does the same job.

Full sleep suspends what the machine is doing: apps pause, network transfers stop, and on a desktop Mac the fans wind down. Waking takes a second or two and everything resumes exactly where it was — sleep costs you nothing but the download that didn't finish. It's the right move when you're leaving for hours. (Careful with a bare long-press of the power button, by the way — held too long, it force-shuts-down the Mac rather than sleeping it.)

Sleep only the displays: Ctrl+Shift+Power

Ctrl+Shift+Power (or Ctrl+Shift+Media Eject) turns off the screens and nothing else. The Mac keeps running: downloads continue, a render finishes, music keeps playing, screen sharing stays up. This is the shortcut most people actually want during the workday — screens dark, work continuing.

Whether waking from display sleep demands your password depends on one setting: System Settings → Lock Screen → Require password after screen saver begins or display is turned off. Set it to Immediately and display sleep doubles as a lock.

Lock vs sleep — and the other routes

If your goal is “nobody touches this while I get coffee”, you don't need sleep at all:

• Ctrl+Cmd+Q — lock the screen instantly. The Mac keeps running and the login screen appears. This is the fastest walk-away shortcut on the platform.
• Hot corner — System Settings → Desktop & Dock → Hot Corners…, then assign Put Display to Sleep (or Lock Screen) to a corner. Flick the pointer there and it triggers — no keys at all. To undo, set the corner back to “–”.
• Close the lid — on a MacBook, still the one-motion classic for full sleep.
• Apple menu → Sleep — the mouse route, always available.

Quick decision guide: leaving for the day → Option+Cmd+Power. Stepping away but the Mac is mid-task → Ctrl+Shift+Power. Just don't want shoulder-surfers → Ctrl+Cmd+Q.

From the Terminal

Both flavors of sleep are also one command away, which is handy in scripts or over SSH:

# sleep the whole Mac right now
pmset sleepnow

# sleep just the displays
pmset displaysleepnow

These are actions, not settings — there's nothing to undo. Wake the Mac the normal way: press a key or click.

If the shortcuts don't seem to work

On MacBooks with Touch ID, a quick tap of the power key can be easy to miss in the combo — press it deliberately along with the modifiers. And if the Mac wakes the instant it sleeps, something is talking to it: a jiggling mouse, a Bluetooth device, or network access. Unplug or turn off the suspect, or check System Settings → Battery → Options (laptops) / Energy settings (desktops) for wake-related options like Wake for network access.

Make sleep actually secure

A sleeping Mac without a password requirement is an open Mac. Check how to require a password on sleep to close the gap — it's one setting.
