Requirements
- Apple-silicon Mac with macOS 15 or later.
- Microphone permission when microphone input is selected.
- System Audio Recording permission when system audio is selected.
- Internet access for GPT Realtime, Gemini Live Translate, custom remote endpoints and initial model downloads.
- Additional free storage and unified memory for optional Qwen models.
- A running local Ollama installation only when using an Ollama model or the Add local model catalogue.
Audio permission problems
Open System Settings → Privacy & Security, then confirm the permission required by the selected input. Restart Übersetz after changing permission if macOS does not immediately expose the new state.
System Audio Recording permission lets the app receive audio through a Core Audio tap. Übersetz does not create a screen-capture stream and does not receive screen pixels.
GPT Realtime does not start
Confirm that your own OpenAI API key is present in Settings, that the OpenAI account can use the selected API and that billing or usage limits have not blocked the request. The key is stored in macOS Keychain; never include it in a support message.
Gemini Live Translate does not start
Confirm that a Google Gemini API key - not an OpenAI key - is present in Settings, accept the provider disclosure, and select a supported target language. Check that the Google project can access the Preview model and has sufficient quota or billing. Gemini may be unavailable because of project, region or Preview-model restrictions; Übersetz does not silently fall back to another provider.
A local model is unavailable
For one of the four managed Qwen models, check free disk space and memory guidance, then retry the resumable download; Übersetz verifies expected size and SHA-256 before installation. For an Ollama model, confirm Ollama is installed and running, refresh the list, and verify the exact tag in Ollama. Catalogue inclusion means runtime compatibility review, not guaranteed translation quality.
