@Etresoft I think you misunderstood what I meant by local solution: I mean stuff like annotations, polylines, polygons (which in would be the user's data) are rendered locally on the map view.

@DTS Engineer This exact issue was actually reported almost 2 years ago, when MapKit support in Quick Look suddenly stopped working with the release of macOS Sequoia. You've said: this use case should be reconsidered. I want to be clear, this is not a bug or oversight, but a deliberate security boundary, However, MapKit in Quick Look was working fine all along (I've started implementing this around the time of macOS 10.15 / macOS 11), until Sequoia came along. It was a supported use case. It is a bug. I've initially filed it via a DTS TSI with Case ID: 9543658. Please attach FB15634383 (https://developer.apple.com/forums/thread/766615) along with this. Very unfortunate that this has dragged on for years without a fix.

Been almost a year. Any updates on this issue? Will it be fixed in Tahoe?

Facing the same issue; have filed report.
