It appears that starting with macOS Sequoia, Quick Look Preview extension no longer loads MapKit maps correctly anymore. Map tiles do not appear, leaving users with a beige background.
Users report that polylines do render correctly, but annotations appears black.
This was previously working fine in prior macOS versions including Sonoma.
STEPS TO REPRODUCE
- Create a macOS app project, with an associated document.
- Ensure project has a Quick Look preview extension, with necessary basic setups.
- Ensure that the extension mentioned in (2) must have a MKMapView. Any other cosmetic changes, etc, does not need to be implemented to observe the base issue. Do note that it has been reported that in addition to the map tiles not loading, annotations don't render correctly as well.
