Wasn’t it Sequoia that introduced a new QuickLook framework that was supported by Dorico from a 5.x point-release sometime in Autumn 2024, after the previous QuickLook framework was deprecated by Apple

You’re correct.

Seee this statement from Daniel

Dorico and macOS 15.0 (Sequoia)

We have been testing on developer betas of Sequoia, and we will provide an official statement about compatibility when (or shortly after) Sequoia is released next week. As Ben says, Dorico’s existing Quick Look generator will no longer work in Sequoia because the old deprecated framework has now been removed. We already have a new Quick Look app extension in Dorico for iPad, which we can port to macOS, but there are some complications with how app extensions are provisioned. We’re not yet sure …
