Apple today released the third Studio Display 17 firmware beta version, two weeks after the release of the second beta version.
It’s worth mentioning that all Studio Displays will be able to receive the update, but this firmware update is limited to Mac computers currently running the new macOS Sonoma operating system.
In short, Studio Display users running macOS Sonoma can now go to System Preferences > Software Update to install the new firmware. Unfortunately, Apple has not yet provided any content related to this firmware update.
