Apple today released a second Studio Display 17 firmware beta, with the update coming two weeks after the release of the first beta.
All Studio Display models are able to receive over-the-air firmware updates, but this firmware update is limited to Macs that are running the new macOS Sonoma operating system at the current time. Studio Display owners running macOS Sonoma can go to System Settings > Software Update to install the firmware.
Apple has not provided details on what’s included in the firmware update and no new features were found by those running the betas.
