In macOS 15 Sequoia, support for deprecated Quick Look Generator plugins (e.g., DTITK_QuickLookPlugin.qlgenerator) has been removed, resulting in broken Quick Look previews for custom file types.

Please migrate to the new Quick Look Preview Extension and Thumbnail Extension APIs to restore Quick Look functionality. These APIs provide information for handling previews and thumbnails for custom file formats.

The FR[AI]ME looks quite polished.  

Not sure if this is allowed, but for anyone looking for a free alternative, I've put together an open source tool for doing this: https://github.com/pmolfese/NIfTIViewQL

Hi Dianne and all,

Apple had decided to completely revamp its internal Quicklook plugin framework in macOS Sequoia.  As a result, to support DTI-TK Quicklook plugin for Sequoia would require a major investment in time and effort that I do not have.

The good news is that AINOSTICS, a UK-based SME in the AI healthcare space, has agreed to put its resources into the development and support of bringing the plugin into the post-Sequoia macOS world.

The result is FR[AI]ME now available on Apple Mac App Store:

https://apps.apple.com/gb/app/fr-ai-me/id6751278949

To allow the company to recoup some of its investment, FR[AI]ME will be available on a subscription basis with a small annual fee.

Hope you enjoy using FR[AI]ME.

Thank you in advance for anything you can do, I am lost without this tool on my mac ; (

Hi,

I would be willing to contribute to the migration to the new APIs. But as far as I can see the source code for the current, deprecated Quicklook Plugin is not included in the DTI-TK repository. Is that correct?

Thanks!

Hi,

I'd like to push this issue, as the depreciation of the quicklook generator breaks a very convenient and time-saving workflow.

Thanks!
