X11 wire protocol capture, replay, and decode for macOS

Download

Download macXcapture for macOS — signed, notarized, ready to run.

MacXCapture for macOS No release yet — first build pending

System requirements: macOS 14.0 (Sonoma) or later. Universal binary — runs natively on Apple Silicon and Intel.

Install

  1. Click the download button above.
  2. macOS unzips the download automatically. (If it didn’t, double-click the .zip in your Downloads folder.)
  3. Drag MacXCapture.app to your Applications folder.
  4. Open it from Applications (or right-click → Open the first time, but you shouldn’t have to — the build is signed and Apple-notarized, so first launch is clean).

That’s it. No installer, no helper daemons, no kernel extensions. The whole thing is just an .app bundle.

What’s in the download

  • The macXcapture GUI app (record / open / replay).
  • The macxcapture CLI tool bundled inside the .app at MacXCapture.app/Contents/MacOS/macxcapture. Symlink it into your $PATH if you want to scriptize captures (the GUI uses the same binary under the hood).
