Which macOS version does Engineering Clock require?

macOS 13 (Ventura) or later. It ships as a universal binary for both Apple Silicon and Intel Macs.

How do I install the screen saver?

After purchase you get a private download link. Unzip it and double-click the .saver file, and macOS adds it to your Screen Saver settings.

Do I need an Apple Developer account to run it?

No. The bundle is ad-hoc signed, so on first launch macOS asks you to confirm: open System Settings, then Privacy & Security, and click Open Anyway, once.

Yes, updates are free forever. You can re-download the latest version any time from your purchase.

A Mac screensaver that makes time look good.
