Compatibility

Installation

  1. Click here to download the latest release
  2. Open Predator.saver (double click)
  3. "Predator.saver" can't be opened because it is from an unidentified developer will appear, press OK
  4. Open Preferences
  5. Select Security & Privacy
  6. Select General
  7. On the bottom side, select Open Anyway

If you see an error message saying “This app is damaged and can’t be opened, you should move it to the trash”, download the file with Safari, to prevent macOS Gatekeeper from throwing that error. Note that some outdated unzip software may cause that issue too.

Important: If you haven’t quit System Preferences before installation and were upgrading from a previous version, I strongly recommend you quit the application after installation, then reopen it, as updated Swift screensavers aren’t loaded correctly in an active System Preferences session.
