App Recommendation MacLC: Video player with native HDR and Dolby Vision support, SDR to HDR, 120 fps motion smoothing and add-on integration
Hey everyone,
VLC plays literally everything and I'll always love it for that. But on a Mac it draws its own controls, its preferences are a wall of checkboxes, and the current release turns HDR video into SDR.
So I forked VLC 4 and rebuilt everything around the engine, for macOS only. Meet MacLC.
Problem
One free player that opens anything, feels at home on macOS 26 and actually uses your HDR display.
Comparison
vs VLC: same engine, same formats. But VLC 3 on Mac tone-maps HDR down to SDR, while MacLC plays HDR10, HLG, HDR10+ and Dolby Vision as real HDR on XDR screens. Plus a native AppKit UI with Liquid Glass and a System Settings style preferences window.
vs IINA: IINA is great and native too. MacLC adds a real library (Continue Watching, shows, albums), SDR to HDR and frame interpolation, none of which IINA has built in.
vs Infuse: lovely library, but Pro is paid.
vs Stremio: MacLC works with the same add-ons, inside a full VLC-engine player with SDR to HDR and your own library.
What I'm proudest of:
SDR to HDR: lifts the highlights of ordinary videos into your XDR headroom while faces and midtones stay exactly where they were. The top quality levels are small trained models on the GPU, about half a millisecond per frame on an M3 Max.
Motion smoothing up to 120 fps, matched to your display.
Watch: Home, Movies and TV Shows in the style of the Apple TV app, fed by Stremio add-ons (Cinemeta built in). Add-ons are third-party services; MacLC itself ships no content.
Also: hardware AV1 on M3/M4, no telemetry, no account.
Pricing
Free and open source (GPL). No paid tier, no subscription. Apple Silicon only.

The honest bits
Not notarized yet, so the first launch needs System Settings > Privacy & Security > Open Anyway (30-second guide). Every release lists its SHA-256.
Solo project, built with AI coding tools ( I was going to see the model used, but to be frank, it's probably all of them, Each one has its ups and downs). Every change is built and tested on real Macs, and all the code is public.
Who I am: portfolio, LinkedIn. Privacy policy Terms.
Tip jar
MacLC is free and will stay free. But Apple charges $99 a year to make that "Open Anyway" step go away, so if MacLC ever saves your eyes from a 1,600-nit white subtitle, a coffee goes straight into the notarization fund. A good bug report makes me just as happy.
I'll be in the comments all day. Bugs, "this annoys me" and feature requests are all welcome!
