FAQ

Common questions and solutions for installation, use, and troubleshooting.

General use

Can't find a podcast?

Check your network. Search uses the iTunes API; if it's unstable, try another country/region or use the link method.

Model download is slow?

Models are downloaded from Hugging Face by default. If download is slow, check your network or try again later.

Transcription is slow?

Try the tiny or base model first; close other CPU-heavy apps. GPU support may come in a later version.

Python environment error?

Transcription requires Python 3.8+ on your system. See the "Python" section below to install it.

macOS: "App is damaged and can't be opened"

The macOS build of CastLoom Pro is not notarized by Apple (distributed outside the App Store), so Gatekeeper may block it and show "damaged" or "can't be opened" on first launch. Remove the quarantine attribute using the steps below, then the app will open normally.

  1. Open Terminal: go to Applications → Utilities → Terminal, or press Command + Space and search for "Terminal".
  2. In Terminal, type this command (there is a space at the end; do not press Enter yet): sudo xattr -r -d com.apple.quarantine
  3. Open the Applications folder and drag the CastLoom Pro.app icon into the Terminal window. The line will then look like: sudo xattr -r -d com.apple.quarantine /Applications/CastLoom\ Pro.app
  4. Press Enter, enter your Mac login password when prompted (nothing will show as you type), then press Enter again. After that, open CastLoom Pro as usual.

Python (required for transcription)

CastLoom Pro's local transcription requires Python 3.8 or newer installed on your system. If Python is not installed, transcription will not work; please install it first.

Official downloads (Python 3.14 or latest recommended):

During installation, we recommend checking "Add Python to PATH" (Windows). After installing, if the app still reports missing Python, restart CastLoom Pro or ensure python3 is on your system PATH.
