There are known issues in the latest Lightroom Classic releases when running on Ventura: Here’s the official Adobe post on Adobe Apps and Ventura. Again, see our notes on these at the end of this post – we’ll update as fixes or new drivers are available. It’s not just Lightroom itself (and there are some issues, although these will be fixed), but we’re also awaiting feedback on compatibility of peripherals. As we hear of more, we’ll update the list. But at this point we’d recommend waiting. However, some issues are already known and are listed below. The short answer is – it’s too early to be sure of all the potential issues. It’s a good question, as the last thing anyone wants is to update their Operating System only to find critical apps either don’t work or don’t work properly. The big question is, do Lightroom and Lightroom Classic work? The newest Mac operating system, macOS 13 Ventura, goes live today.
