**OpenSuperWhisper installation errors typically stem from missing macOS development dependencies, incorrect Rust toolchains, or code signing issues that can be resolved by verifying your Xcode command-line tools, Homebrew libraries, and running the build script with proper environment settings.**

OpenSuperWhisper is a macOS-native transcription application that integrates Whisper-cpp, FluidAudio, and Swift UI components through a complex build pipeline. When installation fails, the error usually originates from one of four layers: the Homebrew formula distribution, the local build script compilation, the model management system, or the Xcode code signing process. Understanding how these components interact according to the Starmel/OpenSuperWhisper source code helps you diagnose failures quickly.

## Understanding the OpenSuperWhisper Build Architecture

OpenSuperWhisper consists of multiple native layers that must compile and link correctly. Knowing which layer produces an error is the first step toward resolution.

The **Brew formula** layer distributes pre-built binaries via `brew install opensuperwhisper`, pulling releases from the GitHub releases page as documented in [`Readme.md`](https://github.com/Starmel/OpenSuperWhisper/blob/main/Readme.md).

The **local build script** ([`run.sh`](https://github.com/Starmel/OpenSuperWhisper/blob/main/run.sh)) orchestrates the entire compilation process. It executes CMake for `libwhisper`, builds the `autocorrect-swift` Rust crate, copies `libomp.dylib`, signs binaries, and invokes `xcodebuild`.

The **Whisper model manager** ([`WhisperModelManager.swift`](https://github.com/Starmel/OpenSuperWhisper/blob/main/WhisperModelManager.swift)) handles model storage in `~/Library/Application Support/ru.starmel.OpenSuperWhisper/whisper-models`, copying bundled defaults and managing async downloads with progress callbacks.

The **app entry point** ([`OpenSuperWhisperApp.swift`](https://github.com/Starmel/OpenSuperWhisper/blob/main/OpenSuperWhisperApp.swift)) constructs the UI, registers the status-bar item, and launches the `TranscriptionQueue`.

The **CI workflow** ([`.github/workflows/build.yml`](https://github.com/Starmel/OpenSuperWhisper/blob/main/.github/workflows/build.yml)) validates the build on clean macOS runners, ensuring the steps work in isolated environments.

## Common OpenSuperWhisper Installation Errors and Solutions

### Homebrew Formula Failures

When `brew install opensuperwhisper` aborts with formula not found errors, the tap may be outdated or the formula URL changed.

Verify the installation source by running `brew info opensuperwhisper`. If the formula is unavailable, download the `.app` bundle directly from the GitHub **Releases** page instead of using Homebrew.

### CMake Configuration Errors (libwhisper)

If [`run.sh`](https://github.com/Starmel/OpenSuperWhisper/blob/main/run.sh) prints "Configuring libwhisper… CMake configuration failed!", you likely lack Xcode command-line tools or use an incompatible CMake version.

Verify your development environment:

```bash
xcode-select -p
cmake --version

```

Install the latest Xcode from the App Store and update Homebrew CMake:

```bash
brew install cmake

```

### Rust/Cargo Build Failures

Cargo failures indicating "cannot find crate `autocorrect-swift`" signal a missing or incorrectly targeted Rust toolchain.

Check your Rust installation:

```bash
rustup show
cargo --version

```

Install the Apple Silicon target and ensure `cargo` is in your PATH:

```bash
rustup target add aarch64-apple-darwin

```

### OpenMP Library Issues (libomp.dylib)

The build fails when copying `libomp.dylib` if OpenMP is not installed or resides in a non-standard location.

Verify installation:

```bash
brew list libomp

```

If missing, install it:

```bash
brew install libomp

```

If installed in a custom Homebrew prefix, adjust the copy path in [`run.sh`](https://github.com/Starmel/OpenSuperWhisper/blob/main/run.sh) to match your system.

### Code Signing and Notarization Errors

When `codesign` returns "no identity" errors, your machine lacks a developer certificate or the signing identity is misconfigured.

For local testing without notarization, [`run.sh`](https://github.com/Starmel/OpenSuperWhisper/blob/main/run.sh) sets `CODE_SIGN_IDENTITY=` to disable signing. For distribution, ensure you have a valid Apple Developer certificate and run [`notarize_app.sh`](https://github.com/Starmel/OpenSuperWhisper/blob/main/notarize_app.sh) with your identity.

### Xcode Build Failures

"BUILD FAILED" messages indicate missing linked libraries or Swift compile errors.

Inspect the build log by running the Xcode command without `xcpretty` filtering:

```bash
xcodebuild -scheme OpenSuperWhisper -configuration Debug -destination 'platform=macOS,arch=arm64' CODE_SIGN_IDENTITY="" CODE_SIGNING_REQUIRED=NO

```

Ensure `libomp.dylib` and `libautocorrect_swift.dylib` exist in the `build/` directory with correct `@rpath` identifiers, as configured by the `install_name_tool` commands in [`run.sh`](https://github.com/Starmel/OpenSuperWhisper/blob/main/run.sh).

### Missing Whisper Models

If the app crashes on launch with "Model not found", the bundled default model (`ggml-tiny.en.bin`) is missing from the app bundle or the app cannot write to Application Support.

Check Console.app for messages from `WhisperModelManager`. Verify the model exists at `OpenSuperWhisper/Resources/ggml-tiny.en.bin` and that the app has write permissions to `~/Library/Application Support/ru.starmel.OpenSuperWhisper/whisper-models`.

## Step-by-Step Troubleshooting Workflow

Follow this diagnostic sequence to isolate the failure point.

First, verify Homebrew dependencies:

```bash
brew update
brew install cmake libomp rust ruby

```

Clone the repository with submodules:

```bash
git clone --recursive https://github.com/Starmel/OpenSuperWhisper.git
cd OpenSuperWhisper

```

Prepare the build script:

```bash
chmod +x ./run.sh

```

Execute a clean build:

```bash
./run.sh build

```

If the script fails at a specific stage, debug accordingly:

- **CMake step**: Run the configuration manually and inspect `libwhisper/build/CMakeFiles/CMakeError.log` for detailed errors.
- **Cargo step**: Build the Rust crate independently to isolate toolchain issues:

```bash
cargo build -p autocorrect-swift --release --target aarch64-apple-darwin

```

- **Library verification**: After each copy operation, verify dylib files exist and check their signatures:

```bash
codesign -v -d build/libautocorrect_swift.dylib

```

- **Model directory inspection**: Open the models directory directly to verify permissions:

```bash
open "$(swift -e 'import Foundation; print(FileManager.default.urls(for: .applicationSupportDirectory, in: .userDomainMask).first!.path)')/ru.starmel.OpenSuperWhisper/whisper-models"

```

## Essential Source Files for Debugging

When troubleshooting OpenSuperWhisper installation errors, consult these specific source files:

- **[`run.sh`](https://github.com/Starmel/OpenSuperWhisper/blob/main/run.sh)** – The primary build orchestrator containing CMake configurations, Cargo builds, library copying, and code signing steps.
- **[`WhisperModelManager.swift`](https://github.com/Starmel/OpenSuperWhisper/blob/main/WhisperModelManager.swift)** – Handles model directory creation, default model fallback logic, and download error handling via `WhisperDownloadDelegate.validationError`.
- **[`OpenSuperWhisperApp.swift`](https://github.com/Starmel/OpenSuperWhisper/blob/main/OpenSuperWhisperApp.swift)** – The application entry point that initializes shortcuts, microphone services, and the transcription queue.
- **[`.github/workflows/build.yml`](https://github.com/Starmel/OpenSuperWhisper/blob/main/.github/workflows/build.yml)** – The CI configuration that mirrors local build steps; compare your environment against the GitHub Actions runner setup.
- **[`Readme.md`](https://github.com/Starmel/OpenSuperWhisper/blob/main/Readme.md)** – Contains the official Homebrew formula references and installation overview.

## Summary

- OpenSuperWhisper installation requires macOS-specific dependencies including Xcode command-line tools, CMake, Rust, and OpenMP.
- The [`run.sh`](https://github.com/Starmel/OpenSuperWhisper/blob/main/run.sh) build script coordinates compilation of C++ (Whisper), Rust (autocorrect), and Swift components; failures typically surface as CMake, Cargo, or code signing errors.
- Model-related crashes originate in [`WhisperModelManager.swift`](https://github.com/Starmel/OpenSuperWhisper/blob/main/WhisperModelManager.swift) when the app cannot access `~/Library/Application Support/ru.starmel.OpenSuperWhisper/whisper-models`.
- Debugging isolated build stages manually—running CMake, Cargo, or `xcodebuild` separately—reveals the specific error obscured by the orchestration script.

## Frequently Asked Questions

### Why does OpenSuperWhisper require macOS-specific dependencies?

OpenSuperWhisper is a native macOS application that combines Swift UI, Whisper-cpp (C++), and FluidAudio with a Rust-based autocorrect library. According to the source code in [`run.sh`](https://github.com/Starmel/OpenSuperWhisper/blob/main/run.sh), these components require platform-specific toolchains: Xcode for Swift/C++, Rust for the `autocorrect-swift` crate, and Homebrew libraries like `libomp` for parallel processing. The app also integrates with macOS-specific APIs for microphone access and Application Support directories.

### How do I fix "CMake configuration failed" when building OpenSuperWhisper?

This error in [`run.sh`](https://github.com/Starmel/OpenSuperWhisper/blob/main/run.sh) indicates missing Xcode command-line tools or an outdated CMake installation. Run `xcode-select -p` to verify your developer directory points to Xcode, then install or update CMake via `brew install cmake`. If the error persists, manually run the CMake configuration command from [`run.sh`](https://github.com/Starmel/OpenSuperWhisper/blob/main/run.sh) and check `libwhisper/build/CMakeFiles/CMakeError.log` for missing headers or library paths.

### What causes the "Model not found" error on first launch?

This occurs when [`WhisperModelManager.swift`](https://github.com/Starmel/OpenSuperWhisper/blob/main/WhisperModelManager.swift) cannot locate the bundled `ggml-tiny.en.bin` model or lacks write permissions to create `~/Library/Application Support/ru.starmel.OpenSuperWhisper/whisper-models`. Verify the model file exists in your build's Resources directory, or manually copy it there. Check Console.app for specific permission errors from `WhisperModelManager`, and ensure the app has full disk access if running from a restricted location.

### Can I build OpenSuperWhisper without a developer certificate?

Yes. The [`run.sh`](https://github.com/Starmel/OpenSuperWhisper/blob/main/run.sh) script sets `CODE_SIGN_IDENTITY=""` to disable code signing for local development builds. This allows you to compile and run the app without an Apple Developer account, though you won't be able to distribute or notarize the application. For unsigned local builds, you may need to right-click the app and select "Open" the first time to bypass Gatekeeper warnings.
