# Requirements

## macOS Menu Bar App

* **macOS 13.0** (Ventura) or later
* **DaVinci Resolve Studio** — Version 19 or later

{% hint style="warning" %}
The free version of DaVinci Resolve is not supported. **DaVinci Resolve Studio** is required for the menu bar app's automated capture workflow.
{% endhint %}

### Enable Local Scripting

DaVinci Resolve must have local scripting enabled for Nobe LutBake to communicate with it. Open **DaVinci Resolve > Preferences > General** and set **External scripting using** to **Local**.

### Python Interpreter

The app communicates with DaVinci Resolve via a Python scripting API. By default, it uses **System python3** (install via Homebrew or python.org).

An optional **Use fuscript (advanced)** toggle is available in **Settings > General > Python Interpreter** when you need Resolve's bundled interpreter for compatibility troubleshooting.

## OFX Plugin

The OFX plugin runs inside DaVinci Resolve on both platforms:

| Platform  | Architecture                      | GPU Backend |
| --------- | --------------------------------- | ----------- |
| **macOS** | Universal (Apple Silicon + Intel) | Metal       |

### Minimum Image Resolution

The source image resolution must be at least as large as the HALD pattern dimensions:

| HALD Level | Pattern Size  | Minimum Resolution | Native LUT Size |
| ---------- | ------------- | ------------------ | --------------- |
| 4          | 64 x 64       | 64 x 64            | 16³             |
| 8          | 512 x 512     | 512 x 512          | 64³             |
| 10         | 1,000 x 1,000 | 1,000 x 1,000      | 100³            |
| 12         | 1,728 x 1,728 | 1,728 x 1,728      | 144³            |
| 16         | 4,096 x 4,096 | 4,096 x 4,096      | 256³            |

{% hint style="info" %}
HALD level 8 is the recommended default. It works with any HD or higher resolution footage.
{% endhint %}
