macOS Native App
StemDeck is now available as a native macOS application (.dmg) for both Apple Silicon and Intel Macs.

-
Native macOS app

Apple Silicon acceleration (MPS)
Stem separation uses Metal Performance Shaders on M1 and newer Macs for significantly improved performance. -
arm64 + x64 builds
Separate native builds are available for both Apple Silicon and Intel architectures. -
Backend watchdog
The Python backend process is automatically terminated if the desktop shell exits unexpectedly.
