Installing

  1. Open the download and drag Sponge to Applications. macOS asks once to confirm an app from the internet.
  2. Sign in with your Sponge account, the same one as the web library. A passkey works.
  3. Save a tab. The first time, macOS asks whether Sponge may see your browser’s front tab. Sponge only asks a browser that’s already open, and only reads its address and title.
  4. Keep sponge running on one computer. A saved link waits in your queue until a computer running sponge captures it. That can be this Mac; the Mac guide sets it up.

Sponge checks for updates daily and verifies each against its signing key before installing. Firefox, Zen, and Orion can’t share their tab; use Share or Save URL (⌘L) there.
