If you use the Nebula software with your Air glasses to emulate free floating monitors, you should be aware that the latest MacOS update is not compatible. The glasses will connect and work as a single display. Launching the software results in a black screen.
The developer is aware of the issue according to comments in several Reddit threads and their own community forums. They are working on a fix, for now the only option is to downgrade to a version prior to 13.3. https://community.nreal.ai/t/nebula-fail-to-work-after-macos-upgrade-ventura-13-3/3778/2
