@ryabov - @byron.jones We are looking to support Mac OS 26 in the next patch, and if not possible for next patch, to reintroduce v1 access until v2 is supported. For now, you can install Photo AI v4.0.4 from your Account page/Legacy section, so you have it as a separate app to use Remove V1. You can also revert to Topaz Photo v1.1.1 here.
