You see this: xcodebuild prints Could not resolve host while it fetches WebDriverAgent’s source. Mobster shows Mobster couldn't download WebDriverAgent. Check your internet connection and build again.

Why it happens

The first build downloads WebDriverAgent. This Mac couldn’t reach the server, so nothing was built.

Fix

  1. Check that this Mac is online and that nothing on your network blocks the download.
  2. Build again from Mobster for Mac.

Check it worked

The build starts compiling instead of stopping at the download. Checked 26 Oct 2026 against Mobster 0.4.0. Back to Troubleshooting.
