SIRIUSX STUDIO · WINDOWS & MAC PREVIEW
Get SiriusX Studio for Windows or the Mac Preview.
Windows x64 and a new macOS Preview for Apple Silicon. Both packages are unsigned while distribution checks finish; Free exploration works without an account.

Open the DMG and drag SiriusX Studio to Applications. It is not yet signed by Apple: on first launch use System Settings → Privacy & Security → Open Anyway. Projects are saved in your Library folder. Isolated repository test runs are Windows-only for now.
Stop the app, back up saved projects using the instructions in your current package, and keep the old installation until you have verified the upgrade.
Windows x64, and macOS 11 or later on Apple Silicon (Preview). Linux and Windows on ARM builds are not offered.
