Finally built like a Mac app. MacLC 1.4 beta, 2026. Website: [hazenstudio.com/maclc](https://www.hazenstudio.com/maclc/). Source code: [github.com/OZBM/MacLC](https://github.com/OZBM/MacLC). A macOS-only media player for Apple Silicon, forked from VLC 4.0.0-dev. It keeps libVLC's complete demuxing and decoding engine and rebuilds everything above it: SDR to HDR on Metal, which lifts highlights into the extra brightness of XDR displays, an HDR path that picks Dolby Vision, HDR10+ or HDR10 for the display, motion interpolation, web video and torrent streaming, a native AppKit interface with a media library, and a Watch section with Stremio-compatible add-ons, sound modes and TV casting. ### Measured results - 6.15× display headroom, measured on an M3 Max - 0.53 ms shader time per 1080p frame - 0.91 ms shader time per 4K frame - 120 fps motion interpolation on ProMotion displays ### Requirements - Apple Silicon (M1 or newer) - macOS 26 Tahoe or later - XDR or external HDR display for SDR to HDR - M3 or newer for hardware AV1 decode ### Licence GPL-2.0-or-later application on the LGPL-2.1-or-later libVLC engine. An independent open-source project, not affiliated with or endorsed by VideoLAN. ### What was built - **MacLC for Apple Silicon** (macOS app): The player itself. SDR to HDR, on Metal, lifts highlights into spare panel headroom while shadows and mid-tones hold still, with quality levels up to a small trained model; plus an HDR format advisor, motion interpolation, web video, torrent streaming, a native library, Watch browsing with add-ons, sound modes and casting to TV.
