The macOS build is Developer ID signed and notarized by Apple. The Windows build is portable: no installer, no admin rights. Mounting a vault as a drive needs a file system component, described below.
macOSVersion 1.2.0 · Apple Silicon
- macOS 26 and later: nothing else to install. The built-in file system extension mounts vaults; switch it on once in System Settings.
- macOS 13 to 15: install macFUSE to mount vaults as a drive.
- Without mounting you can still import, export and preview files in the built-in browser. Intel Macs are not supported yet.

WindowsVersion 1.2.0 · x64 and ARM64
- Windows 10 (2004+) and 11. Single-file portable .exe: double-click and go, no installer, no admin rights.
- To mount vaults as a drive letter, install WinFsp (open source). Without it the built-in file browser still works.
- Native x64 and ARM64 builds. Vault files are interchangeable with macOS. An MSIX installer will follow once we have a code-signing certificate.

SealDisk does not bundle, auto-download or auto-install macFUSE or WinFsp; their licenses require you to get them from the official sites. SealDisk has no auto-update and makes no network requests; come back here for new versions.
