System requirements

Everything Digr 0.1.0-alpha.3 needs, and everything it doesn't run on yet. This page describes the current build — where something is planned rather than absent, it says so and points at the roadmap.

The machine

  • macOS 11 Big Sur or later. This is what the app bundle declares as its minimum system version.
  • Apple silicon. The release is built for aarch64-apple-darwin. There is no Intel or universal build, and none currently planned.
  • Disk space for the index and artwork cache, not for your music — Digr never copies your files. A large library's index and cached covers are measured in tens of megabytes, not gigabytes.
  • No network required to run, scan or play. A local network is needed only to cast.
  • No account. There is no sign-in and no user record, and there is no plan for Digr Free to need one. The current alpha also has no licence key of any kind — that is a statement about this build, not a permanent commercial promise: Digr Pro is priced, and a paid tier will eventually need some way to prove you paid for it.

Audio formats

Two different lists, because indexing a file and decoding it are two different jobs.

  • Indexed with full metadata: MP3, FLAC, ALAC, M4A, AAC, WAV, OGG. Tags, artwork and duration are read and the track is filed into your library whatever your machine can play.
  • Plays locally on macOS: MP3, FLAC, ALAC, M4A, AAC, WAV. Decoding is the operating system's job in this build, so OGG depends on your machine's codecs. When a file can't be decoded, Digr says so on that track rather than skipping it in silence. A native decoder that lifts this limit is on the roadmap.
  • Cast: whatever plays locally is streamed to the device as the original file. No transcoding step, silent or otherwise.

Casting

  • Google Cast — Chromecast, Google Home speakers and Cast speaker groups. It is the only protocol implemented today.
  • Same network. Discovery uses mDNS and the device fetches audio from a server running on your Mac, so both need to be on the same LAN. Client isolation on a guest network will prevent it.
  • No AirPlay, DLNA/UPnP or OpenHome today. All three are on the roadmap rather than ruled out — they are simply not in this build.

Not supported today — but planned

Digr is a Tauri application, so these are buildable. What none of them has yet is a build that has been packaged, signed and tested against real audio hardware, and until that exists this page will not claim support for it.

  • Windows. A planned future production platform. Not built or tested yet.
  • Linux. Planned after Windows.
  • AirPlay, DLNA/UPnP and OpenHome. Future network-audio work; Google Cast is what ships now.
  • Metadata and tag editing. Digr reads your files and never writes to them in this build. Explicit, reviewable, undoable tag editing is planned.

Not planned

  • Intel Macs. The release workflow targets Apple silicon. A universal binary is possible but not currently planned.
  • iOS and iPadOS. Not on the roadmap.
  • Streaming services and cloud libraries. Not an omission — the point.
  • Network-attached libraries unmounted mid-scan. A share that disappears during a scan is handled safely rather than supported: the root is preserved, not pruned. Proper NAS reconnection is on the roadmap.

The full picture — what is implemented, what is planned at each horizon, and what is genuinely ruled out — lives on the features and roadmap page.
