macOS 14 Sonoma is out already, and although the latest version of Mitti and Vezér runs fine on it, there is no reason to rush upgrading primary systems until Apple releases at least the first dot release.
Mitti 2.5.3 and previous versions has compatibility problems with macOS 14 Sonoma, so make sure you are using at least Mitti 2.5.4 on the new operating system.
Unfortunately we were not able to test every possible hardware and software combinations, so if you are running into any issues, please don't hesitate to contact us!
