Browse your Microsoft Fabric OneLake data lake from Finder, the same way OneDrive or Google Drive integrate. Multiple accounts in multiple tenants, side by side, with a single Homebrew install.
Microsoft ships a OneLake File Explorer for Windows only. There is no native macOS equivalent. This project fills that gap as an open-source .app distributed through Homebrew, with these explicit improvements:
- Multi-account, multi-tenant simultaneously visible side by side.
- macOS-native UX through a File Provider Extension — Finder sidebar, online-only placeholders, on-demand download, Spotlight integration.
- No system-level changes required from the user (no kernel extensions, no Recovery Mode tweaks).
- Single-command install via Homebrew.
