CoreVideo v0.1.45-beta.1

macOS pre-release, Apple Silicon only. Windows users: stay on v0.1.44.

Install

macOS installer replaced September 6, 2026: The original macOS downloads were withdrawn due to signature errors. Download the replacement .pkg below, even if you downloaded this version previously. It was built locally from PR #251 (commit e96b15ba0c0389c7a6255a6f767294d74fcefb5c), signed with Developer ID certificates, notarized and stapled. Installer validation, installation, and a runtime test passed on the maintainer’s Mac. The old ZIP is no longer provided.

Easiest — double-click CoreVideo-Setup-v0.1.45-beta.1.pkg. It installs to your own user account, so it will not ask for an admin password. Restart OBS afterwards.

This is the first notarized macOS build

Earlier macOS betas were ad-hoc signed, so macOS quarantined them and you had to clear the attribute by hand before OBS would load the plugin. That step is gone. This build is signed with a Developer ID, notarized by Apple and stapled — it installs like any other signed Mac software and works offline on first launch.

What to expect on first run

• One round of permission prompts — keychain, camera and microphone. Choose Always Allow for keychain items; they won't come back.
• Starting the engine asks the host for recording permission. Zoom requires local-recording rights before raw video and audio can start, so the first attempt requests it. Once the host grants it, start the engine again. This is normal, not an error.

Requirements

• Apple Silicon Mac (M1 or later). Intel is not supported.
• OBS Studio 30 or later.
• A Zoom account, and a meeting host who will grant recording permission.

What's in this build

This is the first macOS build carrying the whole v0.1.33–v0.1.44 line of audio and recording work — the previous macOS beta (v0.1.32-beta.1, 1 August) predates all of it. Audio ring rework, silence-resume fade, drift correction, FFmpeg preload, ISO recording timing, and the colour-range fix are all new to macOS here.

Also fixed in this release:

• Tiles works on macOS. Its shader was never being copied into the bundle, so the feature was dead on every previous macOS install.
• The record-permission step no longer pops an error dialog. It's a notice that tells you what to do and clears itself once media starts.

Known limitations

• Talkback is Windows-only. The Talkback dock appears on macOS but is inert and says so — the engine-side port is in progress.
• To capture your own screen, use OBS's native macOS Screen Capture source. The CoreVideo share source carries other participants' shares.
• The download is ~270 MB because the Zoom SDK ships inside it. The plugin itself is about 2 MB.

Feedback

This is a test build — please report anything odd. The OBS log (Help → Log Files → Show Log Files) is the most useful thing to include.
