Install Nap.

Two ways, both about a minute. Nap needs macOS 13 or later, and runs on Apple silicon and Intel.

Terminal

No warnings.

Paste this into Terminal and press Return. It downloads Nap, checks it against the published checksum, and puts it in your Applications folder.

curl -fsSL https://trynap.app/install.sh | bash

macOS only questions apps a browser downloaded, so installing this way opens Nap without a single prompt. The script is plain text you can read first: trynap.app/install.sh.

Download

The familiar way.

Drag Nap to Applications, as with any Mac app. macOS asks you to confirm the first time you open it. The three steps below show exactly what you'll see.

Download Nap for Mac

Nap is signed by Scanner Techs but not notarised by Apple, so macOS asks you to confirm it once, by hand. Nothing else changes.

If you downloaded it

Three steps, once. Skip this if you used the Terminal line.

  1. Drag Nap to Applications

    Open the downloaded Nap.dmg and drag Nap onto the Applications folder, then eject the Nap disk from Finder's sidebar.

  2. Open it once. macOS will stop it.

    Open Nap from Applications. macOS says it can't verify the developer and offers two buttons: Done and Move to Trash (Move to Bin in British English). Click Done, thenopen System Settings to allow it — that's step 3.

    This dialog has no Open Anyway button; since macOS 15 that lives in System Settings. Apple only vouches for apps it has notarised, which needs a developer account Nap doesn't have.

  3. Click Open Anyway

    Open System Settings → Privacy & Security, scroll toSecurity, and next to “Nap” was blockedclick Open Anyway. Confirm with Touch ID or your password.

    The button only appears for about an hour after step 2. If it isn't there, open Nap again and come back.

Then open Nap

The app does the rest. Same for both ways of installing.

  1. Press Install

    Nap puts the screensavers where macOS keeps them, and tells you whether they're installed and selected.

  2. Choose it in System Settings

    Press Open Screen Saver Settings and Nap takes you to the right pane. macOS files other people's screensavers under Others — press Show All if you don't see Nap.

  3. Walk away

    It starts when your Mac goes idle. Your free trial runs from the first time Nap opens; after that it needs a key.

Questions

Why does macOS warn me at all?
Apple notarises apps for developers enrolled in its program. Nap is signed by Scanner Techs so macOS can tell every version apart, but it isn't notarised, so the first open needs your say-so. Installing from Terminal skips the warning because macOS only questions browser downloads.
Is it safe to pipe a script into bash?
Read it first — that's the honest answer for any such line. Ours is at trynap.app/install.sh: it downloads one file, checks it against its published SHA-256, refuses it if they don't match, and copies Nap to Applications. It never asks forsudo.
How do I update?
Nap tells you when there's a new version and updates itself, so new screensavers just turn up. You can also run the Terminal line again, which replaces the copy you have.
How do I remove it?
curl -fsSL https://trynap.app/uninstall.sh | bashremoves Nap, the screensaver and your settings. It keeps your licence, so reinstalling doesn't ask for the key again.
Will I lose my licence if I reinstall?
No. The key is recorded for the Mac, not for the app, so removing and reinstalling Nap keeps it. Moving to a different Mac is in support.
