macOS 26 Tahoe has released with a brand new UI design called Liquid Glass. While the latest version of Mitti and Vezér appears to run without issues on the new OS, we strongly recommend not rushing to upgrade critical systems until Apple ships at least the first maintenance update.
As always, please make a full backup before upgrading, and double-check that all of your software and hardware components are fully compatible with the new OS.
It’s also worth noting that Apple has confirmed macOS 26 Tahoe will be the final release to support Intel-based Macs - and even then, only four (!) Intel configurations are officially supported.
Unfortunately we weren’t able to test every possible hardware and software combinations, so if you are running into any issues, please don't hesitate to contact us!
