README
OneLake Explorer for macOS
**Browse Microsoft Fabric OneLake from Finder.** Like OneDrive or Google Drive — but for your data lake. Multiple accounts in multiple tenants, side by side, with a single Homebrew install.
> Pre-release, under active development.
📖 **Documentation, screenshots and walkthroughs: [ofem.debruyn.dev](https://ofem.debruyn.dev)**
## Install
```bash
brew install --cask sdebruyn/ofem/ofem
```
Requires macOS 14 Sonoma or later on Apple Silicon. No system-level changes, no extra dependencies, no admin password.
[Full install guide →](https://ofem.debruyn.dev/install/)
## What you get
- Multiple OneLake accounts across multiple Microsoft Entra tenants visible side by side in Finder.
- Online-only placeholders by default — files stream on demand, cached locally for instant reopen.
- Drag, drop, double-click, save in any app. Spotlight indexing and Quick Look work out of the box.
- One Finder sidebar entry per account (`OneLake — work`, `OneLake — client-a`, …) so workspaces from different tenants never collide. macOS places each one under `~/Library/CloudStorage/OneLake-/`, the same way OneDrive and Google Drive do.
## What's not here
Things managed by Microsoft Fabric and not exposed through the file system: creating or renaming workspaces, managing permissions, changing the schema of Delta tables. Those still go through the Fabric portal.
## Strict tenant? Bring your own App Registration
OFEM ships with a multi-tenant Entra App Registration that works for most users. Tenants that block third-party multi-tenant apps can supply their own client ID in *Add Account → Advanced* — see [Custom App Registration](https://ofem.debruyn.dev/custom-app-registration/) for the exact registration settings.
