MacOS26 Tahoe USB2 Class2 Interface issue with Mytek legacy DACs
We have received from the field, and confirmed in September 2025 an USB2 Class2 audio interface compatibility issue on certain Mac hardware when the Mac computer is updated to Tahoe. Mytek DACs is not detected as an audio device in Tahoe. Technically, all these DACs as well as Tahoe should be compatible with USB2 Class2 standard and working, but there appears to be some bug in the initialization data string which Mytek programmers are now working to identify and fix. The USB2 interface for legacy DACs has been developed by our former contract manufacturer , HEM Electronic of Poland, we stopped collaborating with in 2021, but now we have approached HEM for assistance with providing a quick solution to the issue. Please check this page every few days for updates and resolution. In meantime hold off with an update to Tahoe if possible. Mytek Tech Support.
