We are excited to announce that Observatory 2.1 is fully compatible with macOS 15 Sequoia, which Apple is releasing today. Apple always introduces regressions in new major macOS releases, and this one is no different, but after testing Observatory 2.1 with the release candidate we found no more issues with it or its Quick Look and Spotlight extensions.

Observatory 2 requires an Observatory 2 license in order for it to run on macOS Sequoia. Observatory 1 is not supported.
