Important

macOS first launch (no code signing yet). After dragging StemDeck to Applications, clear the Gatekeeper quarantine flag or macOS will say the app is damaged:

xattr -dr com.apple.quarantine /Applications/StemDeck.app

Upgrading from alpha.9 or earlier? If after installing you still see an old version or are missing recent features, clear the cached runtime once and relaunch:

rm -rf ~/Library/Application\ Support/StemDeck/runtime ~/Library/Application\ Support/StemDeck/runtime.old

What's new in 0.7.0 Alpha 16

GPU support

  • NVIDIA RTX 50-series (Blackwell) support. Cards with the sm_120 architecture (e.g. RTX 5060 Ti / 5070 / 5080 / 5090) now run stem extraction on the GPU. Previously they failed with CUDA error: no kernel image is available for execution on the device - StemDeck now installs a CUDA 12.8 / PyTorch 2.7 build on these cards while every other GPU keeps its existing setup. (#218, fixes #217)
  • Cleaner CPU fallback. If a GPU reports CUDA available but can't actually run kernels, StemDeck now detects it at setup and falls back to CPU instead of crashing mid-extraction. (#218)

Security

Installing

  • macOS: drop the .app into Applications and launch (run the xattr command above first).
  • Windows: unzip the downloaded .zip, then run StemDeck.exe from the extracted folder.

Artifact build

  • macOS arm64 and x64 DMGs and runtime packs were built and inspected on a macOS GitHub Actions runner before upload.
  • Windows portable packages were scanned with ClamAV in CI before upload.
