MKVToolNix 99.0 — macOS (v99.0-b2026.05.1)

Unofficial macOS builds of MKVToolNix 99.0.

First launch: drag to Applications and open it. The first time, macOS blocks it — open System Settings → Privacy & Security and click Open Anyway (not "Move to Trash"). It opens normally after that.

Prefer Terminal?

Run xattr -cr /Applications/MKVToolNix.app to clear the quarantine flag in one shot.

Downloaded the wrong architecture?

If you get a "bad CPU type" error, check Apple menu > About This Mac.
"Apple M_" = Apple Silicon DMG. "Intel Core" = Intel DMG.

Verify download integrity

Each DMG has a matching .sha256 file in the assets. Download both, then:

shasum -a 256 -c MKVToolNix-99.0-macos-apple-silicon.dmg.sha256
# -> MKVToolNix-99.0-macos-apple-silicon.dmg: OK

[RETRACTED] MKVToolNix 98.0 — macOS (b2026.04.1)

⚠️ RETRACTED — this build crashes on launch unless specific Homebrew packages are present (double-conversion, pcre2, zstd, libpng, md4c, freetype). Use the latest release. The RETRACTED.txt asset has the full root cause.

Original DMGs have been removed. Tag preserved for historical reference (referenced in PATCHES.md and CHANGELOG.md).
