We’ve just released Observatory 1.6.2 on the Mac App Store, a minor update focused on bug fixes.
It resolves an issue with Quick Look on Apple silicon, and missing metadata for the Keck Observatory Archive in Virtual Observatory. The latter was caused by a change in the Keck Observatory Archive service, and it could also lead to an error when saving the library.
Initial tests of Observatory on the first beta of the next major macOS version that will be released this fall, macOS 12 Monterey, didn‘t uncover any issues, so unless Apple breaks something along the way, I am hopeful that this will be a good upgrade from macOS 11 Big Sur.
