Version 0.2.0-alpha.62. What changed.

Generation, stem separation, and training run on an NVIDIA GPU. The installer is not code-signed, so Windows SmartScreen may warn on first install: choose More info, then Run anyway. Installed apps update themselves over signed releases.

What runs on which hardware: Models, hardware, and first run. Building it yourself: from source.

macOS Preview

Mac preview: please test and report bugs. Version 0.2.0-alpha.62, macOS 14 or later, Apple Silicon or Intel. It is built and tested on a virtual Mac in CI, but nobody has run it on a real Mac yet: you are the first testers. Expect rough edges and tell us what breaks.

Mac preview: Apple Silicon (M1 and later)

Installing (the app is not signed by Apple)

  1. Open the dmg and drag Iblis to Applications.
  2. Open Iblis. macOS says it cannot verify the developer: press Done (or Cancel).
  3. macOS 15 and later: System Settings, Privacy & Security, scroll to "Iblis was blocked", press Open Anyway, enter your password, then Open Anyway again. macOS 14: Control-click (right-click) Iblis in Applications, choose Open, then Open.
  4. Or in Terminal: xattr -dr com.apple.quarantine /Applications/Iblis.app, then open it normally.

Check a download with shasum -a 256 Iblis-*.dmg and compare it with the SHA-256 above. You only do steps 2 to 4 once per downloaded version.

Known not to work on Mac yet

  • Training your own styles needs Windows and an NVIDIA GPU. The Training page says so on a Mac.
  • No self-update. Download the new dmg from this page and replace the app; your library, styles, and settings stay in ~/Library/Application Support.
  • Generation and stem separation on Apple Silicon: install ACE-Step 1.5 and a Demucs stems pack from the Plugins page (Metal; if Metal fails, Iblis moves the engine to the CPU by itself). They need Iblis 0.2.0-alpha.62 or newer. Their speed on real Macs is not measured yet. Intel Macs get the app (library, player, cloud providers) but no local generation or stems engine yet.
  • macOS may ask for Keychain access again after an update (stored cloud keys), because the app is not signed.
