Are there plans for an Apple Silicon native version of Cubit?

No, unfortunately, there will be no Apple Silicon native version of Coreform Cubit; in fact, the opposite. Due to a key component supplier of Coreform Cubit dropping support for Mac, we will discontinue development of Coreform Cubit on the Mac entirely after January 1, 2025.
