freemkv Homebrew tap

Install freemkv — rip and remux Blu-ray, UHD, DVD and HD DVD discs to MKV.

Desktop app + command line (macOS)

brew install --cask freemkv/tap/freemkv
freemkv --version

Installs freemkv.app and links the freemkv command from inside it.

Command line only

brew install freemkv/tap/freemkv-cli
freemkv --version

macOS, Linux, Apple Silicon and Intel. Same freemkv command, no app. Install one or the other, not both.

Renamed in 1.8.0: the cask was freemkv-app and the CLI formula was freemkv. Existing installs follow the rename on the next brew update / brew upgrade.

autorip

The unattended ripping daemon:

brew install freemkv/tap/autorip

Firmware tools

freemkv-flash (flash/dump drive firmware) and freemkv-fw (build/modify firmware images) — two tools, each shipping a CLI (formula) and a macOS desktop app (cask):

# flash — CLI + app
brew install freemkv/tap/freemkv-flash
brew install --cask freemkv/tap/freemkv-flash-gui

# modify — CLI + app
brew install freemkv/tap/freemkv-fw
brew install --cask freemkv/tap/freemkv-fw-gui

Why install this way

A binary downloaded in a browser gets macOS's com.apple.quarantine attribute, and freemkv is not notarized by Apple — so the download is refused with "Apple could not verify freemkv is free of malware". On macOS 15 Sequoia the old right-click → Open bypass no longer exists; the only route is System Settings → Privacy & Security → Open Anyway, per download.

Homebrew fetches with curl, which never sets that attribute, so the formula installs and runs with nothing to click through. The cask sets quarantine false for the same reason.

That is a real trade, not a trick: it moves the trust decision from Apple's notary service to this tap. What you get instead of a notarization ticket is a sha256 pinned in this repository and verified on every install, against release assets built in public by a workflow you can read. If you would rather have Apple's guarantee, there is none to be had yet: no freemkv download is notarized, and a copy from the releases page has to be allowed once in System Settings.

Keys

freemkv ships no key database. Decrypting a commercial disc needs one, or a key service:

freemkv update-keys

Updating

This tap is updated automatically by the freemkv and freemkv-firmware release workflows (update.sh) — the versions and checksums here are written when a release is published, not by hand.
