nbviewer-app Not rendering on macOS Sequoia

This may well be a usage mistake on my side (new to Jupyter notebooks): I installed the viewer via brew, removed it from the quarantine and can use it to view ipynb files by opening them. However, looking at them via quicklook only shows me the the unrendered code, not the rendered notebook. Am I doing something wrong or is this view not supported in quicklook? Many thanks for your help!

Quicklook extensions haven't worked for me for at least a couple years of macOS updates 😞

FWIW, Quicklook was working for me until I updated to Sequoia.

Same for me, the issue does not seem to occur in Sonoma, where the rendering is just fine.

Same here, after updating to Sequoia I have lost the ability to preview rendered notebooks!

Same here! I haven't found time to debug this. My guess is that macOS rejects unsigned QuickLook extensions starting with Sequoia.

From another site with similar issues: "From 2019, with the release of macOS Catalina (10.15), Apple introduced the new Quick Look Preview and Thumbnail Extensions, encouraging developers to migrate from the older Quick Look Generator plugins. This marked the start of a transitional phase where the legacy API was deprecated, but not yet removed, giving developers time to adapt their applications to the new framework. However, the formal announcement that the old Quick Look Generator plugins would be fully removed came in June 2024 during WWDC, when Apple unveiled macOS 15 Sequoia. This gave developers a clear deadline, as they were informed that starting with macOS Sequoia, which was released in September 2024, the deprecated Quick Look plugins would no longer function."
