Still no support for the Sony A7RV camera RAW files. Ventura now does, but still nothing for Monterey. As a Sony photographer, this s very frustrating.
Thanks for the feedback. Hard to believe that they will add new functionality during this security fixing updates. Older macOS generations won’t get any enhancements besides security patches. You’ll have to be to the current version to get the enhancements. If your Mac isn’t compatible with Ventura you’re forced to upgrade it…
