ipynb-quicklook

The plugin provides a macOS Quick Look generator that renders Jupyter and IPython notebook files directly in the Finder preview pane. When a *.ipynb* file is selected and the space bar is pressed, the generator uses nbviewer.js to produce an on‑the‑fly HTML rendering of the notebook’s contents, allowing users to inspect code, markdown, and outputs without opening the notebook in an editor.

Installation requires downloading the compiled `ipynb-quicklook.qlgenerator` bundle, removing Apple’s quarantine attribute on recent macOS versions, and placing the bundle in the system‑wide `/Library/QuickLook` directory. After resetting the Quick Look server with `qlmanage -r`, the preview becomes available for any notebook file on the machine.

The project is distributed under the MIT license, is considered stable, and has been superseded by the native Jupyter Notebook Viewer macOS app, which is the recommended method for installing the Quick Look functionality.
