Installing one

  1. 1

    Buy it

    Click "Add to cart" — each screensaver is $1 — then check out whenever you're ready. No account needed.

  2. 2

    Open the .saver file

    Safari unzips it automatically — find it in your Downloads folder (or the browser's download tray) and double-click it. Everything here is signed with a Developer ID certificate and notarized by Apple, so Gatekeeper won't show any "unidentified developer" warning.

  3. 3

    It installs itself

    Double-clicking installs it to ~/Library/Screen Savers and opens System Settings straight to the Screen Saver pane with it already selected.

Why you can trust these downloads

Everything on this page is built and signed by me, Ryan Clayton, under my own Apple Developer ID (Team ID AWLLM3Q8GW). Each is also notarized: Apple independently scanned the exact binary you're downloading and issued it a ticket, which is stapled to the file so Gatekeeper can verify it offline. You don't have to take my word for any of that — check it yourself after downloading:

spctl -a -vv -t install ~/Downloads/<Name>.saver

That should print source=Notarized Developer ID and origin=Developer ID Application: Ryan Clayton (AWLLM3Q8GW). If it doesn't say exactly that, don't run it. The source is also public if you'd rather read the code than trust a signature:

Photosensitivity warning: these patterns include rapid flashing, strobing, and high-contrast pulsing — especially Bloom, Hypno, and Shatter. If you or anyone in your household has photosensitive epilepsy or a seizure disorder, use caution or skip these.
